Abstract

Polymer thin films and surfaces play a major role in the functionality of many components in the microelectronic and automotive industries. The characterization of their mechanical properties at a nanometer scale remains a technological challenge. Instrumented indentation testing with frequency-specific dynamic analysis provides access to viscoelastic measurement of near surface properties of polymeric materials. Development of biomaterials for tissue replacement raises the interest for testing polymers with storage modulus of less than 1 MPa. The development of specific testing methodologies with improved accuracy and precision for evaluating very soft polymeric materials are presented in this work. Results at various frequencies for polyurethane and polydimethylsilane using both Berkovich and Flat punch geometries are compared.
