Analyzing and Modeling Mechanical Properties of Aging Photothermally Cured Polydimethylsiloxane (PDMS)

Duncan McQueen

This study compares the aging tensile behavior of 0.1 weight percent carbon black PDMS thin films cured via oven, ambient, and laser-based methods using carbon black nanoparticles. Dynamic Mechanical Analysis reveals that Young’s Modulus increases over time for all methods, suggesting significant rising stiffness in short term aging. Toughness and ultimate tensile strength remain stable, suggesting crosslink density plays a role in the tensile changes observed.
