Image Logger for TT-2 Atomic Force Microscope – An overview!

The Image Logger for the TT-2 AFM features the ability to view forward and reverse images for six channels, display real time oscilloscope-data logger for 6 channels and visualize the spectrum of the 6 data channels.

Image Logger Features

• View forward and reverse images for six channels
• Display real time oscilloscope-data logger for 6 channels
• Visualize the spectrum of the 6 data channels

A great advantage of an atomic force microscope is that it can capture several types of images. Each type of image reveals critical information about the surface topography or physical parameters.

Software

It is possible to display up to six channels from the Z feedback control loop in an atomic force microscope. These include:

• Z Error
• Z Drive (topography)
• Z Sensor
• Phase
• L-R (friction)
• Amplitude

Additionally, these channels may be displayed in the forward and reverse scan directions. With the data logger it is possible to display all six channels of data in the forward and reverse direction. This capability allows real time visualization of all channels.

Image Logger

The image logger simultaneously displays six image channels in forward and reverse directions. During scanning, the palettes and the histogram can be updated. Once a scan is completed, all twelve channel imagescan be saved.

Real Time Oscilloscope

Software for Focus Assist is integrated with the AFMControl software used on the TT-2 AFM. Using the software is easy. Simply focus the optical microscope on the probe, and then on the sample. Once this registration is completed, you can use the software to move directly to the sample, to the probe, or you can even have the optic follow the probe during probe approach.

Spectrum Analyzer

The spectrum of one input data channels can be displayed. Several types of windows and averaging algorithms may be applied to the incoming data stream. Identifying sources of unwanted vibrationsis possible with the spectrum analyser function.

AFM accessories include focus assist and image loggers for AFMs, replacement scanners, probe holders, electronics, and stages, dunk and scan and environmental cell scanning options, and documentation packages for all AFMWorkshop atomic force microscope products. Customers can purchase a standalone AFM stage and customize it to their needs using various scanners and light levers. Environmental cells and dunk and scan packages allow AFM scanning for samples submerged in liquids and inert gas. For more details, please visit www.afmworkshop.com or call at 1 (888) 671-5539.

15 Micron Atomic Force Microscope Scanner for High-Resolution Scans

The 15-micron scanner is interchangeable with the 50-micron or 100-micron scanner in the TT-2 AFM or HR-AFM. Extremely high-resolution scans are made with the 15-micron scanner.

Description
The PS-2010, PS-2011 and PS-2019 piezoelectric scanners are designed for use with the AFMWorkshop TT-2 and HR-AFM Atomic Force Microscopes, and scan samples in the X, Y, and Z-axis. Both products use temperature compensated strain gauges for linearizing scans in the X and Y-axis. The PS-2010 and PS-2019 have temperature compensated strain gauges in the Z-axis, while the PS-2011 does not.All scanners use a modified tripod design for creating motion in the XY axis. Motion is generated through a lever arm. The lever arm in the 50 µm scanner is approximately 5:1, in the 100 µm scanner it’s 10:1 and in the 15 µm scanner, it is 1:1. Animations on the AFMWorkshop website illustrate how the scanners operate. Each scanner contains a PC board with circuits for measuring ceramic motion with the strain gauge, as well as a 20-pin ribbon cable connector. The scanners are attached to the XY manual positioner with three M6 socket head screws.

Sample Holding Stage
Mounted on standard AFM metal disks, samples are held on an aluminum metal plate with two magnets. As shipped, the sample holder is electronically grounded to the microscope stage to help eliminate unwanted effects from sample charging. Included with each scanner is a leveling sample puck. The puck enables samples to be leveled, reducing the AFM image background bow to less than a few nanometers. The leveling sample puck is magnetically held to the sample stage, and has three set screws to level the puck relative to the XY scan axis.

Interchangeable
The 15 µm, 50 µmand the 100µm scanners are interchangeable. The scanners are removed from the TT-2 AFM stage by simply unscrewing three M6 socket head screws and unplugging a 20-pin ribbon cable. It takes less than 5 minutes to remove one scanner and to replace it with another scanner. The 15 µm scanner is our recommendation for highest resolution scanning and lowest noise on the TT2-AFM and HR-AFM.

AFM accessories include focus assist and image loggers for AFMs, replacement scanners, probe holders, electronics, and stages, dunk and scan, and environmental cell scanning options, and documentation packages for all AFMWorkshop atomic force microscope products. Customers can purchase a standalone AFM stage and customize it to their needs using various scanners and light levers. Environmental cells and dunk and scan packages allow AFM scanning for samples submerged in liquids and inert gas. For more details, please visit www.afmworkshop.com or call at 1 (888) 671-5539.

How Atomic Force Microscopes Useful in The Study of Polymers

AFM is a powerful method for imaging polymers, polymer blends, and polymer composites with nanometer lateral resolution. For polymer applications, the AFM now resides alongside optical microscopy and electron microscopy (SEM – scanning electron microscopy and TEM – transmission electron microscopy) as essential tools for characterization. However, atomic force microscopy provides specific advantages over other microscopies because it provides mechanical interaction between the tip and sample. This mechanical source contrast often provides contrast in situations where electron or photon-based microscopies struggle or even fail.

The predominant mode for imaging polymers is phase imaging, which is associated with vibrating mode. In phase imaging, the AFM provides excellent contrast, sensitivity, and discrimination based on various material properties of the polymers.

Key Benefits of AFM

• Suitable for polymers, polymer blends, polymer composites
• Used to establish structure-property relationships
• Lateral resolution is ~10nm
• Information obtained includes morphology, dispersion, domain size, internal structure
• Sample preparation – cryo-microtoming – often needed to remove skin effects from molding, other processing methods
• Phase imaging is excellent method for contrast where contrast is based on material/mechanical properties such as stiffness and adhesion
• No post processing needed

Phase Imaging

The predominant mode for imaging polymers is phase imaging, which is associated with vibrating mode. In phase imaging, the AFM provides excellent contrast, sensitivity, and discrimination based on various material properties of the polymers including stiffness and adhesion.

Phase imaging is a channel collected in vibrating mode and requires no post processing. Phase imaging collects the information on the phase shift (Φ) induced in the cantilever vibration motion. The cantilever is driven at a resonant frequency and interacts with the sample at a given oscillation amplitude set by the user. The phase shift (Φ) is then induced by interacting with the sample and is mapped as a channel simultaneously with the topography channel while the tip raster scans over the surface. A variety of material properties can affect the tip-sample interaction and induce a phase shift including stiffness, adhesion, viscoelasticity, and capillary forces.

Sample Preparation

AFM imaging requires flat surfaces for imaging. However, polymer samples may require additional sample preparation beyond this. If there is a sample with a “skin”, or a sample that has been processed and only the inner bulk material needs to be imaged, it will need to be cryo-microtomed for AFM imaging. Cryo-microtoming is a process by which a very smooth surface is cut and prepared at cold temperatures on a cryomicrotome. Many samples such as thin films or spin-coated films can be imaged as is without this preparation.

A side from cryo-microtoming, no further sample preparation is required – i.e. no staining is required as is the case for electron microscopy-based methods such as scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

Our AFM Users Recent Polymer Reference Publications

AFMWorkshop’s TT-AFM provides all the major Atomic Force Microscopy (AFM) modes needed to characterize polymers, including vibrating mode for topography/morphology and force distance curves for mechanical properties such as adhesion and stiffness. A number of researchers have published their work on polymers using the TT-AFM, characterizing important properties such as size, shape, and dispersion.
