Abstract

In this project, we dispersed graphene nanoplatelets (GNPs) into a polydimethylsiloxane (PDMS) elastomer matrix to test the nanocomposite’s mechanical responses after being exposed to near-infrared light in five timed illumination cycles of on for 90 seconds and off for 50 seconds. Different concentration levels of GNP to PDMS (0.1-2 wt%) nanocomposites were fabricated and varying levels of pre-strain (3%-40%) were applied to each test sample before it underwent the 5 illumination cycles. Highly stretched test samples showed reversible contraction while lowly stretched test samples showed reversible expansion.
