AFM for Polymer Research
Polymers are ubiquitous in materials science research as well as everyday life products. Polymer properties are varied and AFM is an excellent tool to study them on many levels. In addition to accurate measurement of polymer film topography, the wide range of AFM techniques available on Asylum Research instruments allows for study of diverse polymer properties ranging from molecular chain arrangement in crystallites to domain modulus and conductivity.
