Near-Infrared Light Induced Mechanical Responses in Single-to-Few Layer Graphene

Loomis J., King B., Panchapakesan B., University of Louisville, US

Layer dependent physical responses of graphene-based polymer composites to near-infrared (NIR) light are reported. Thin film polymer composites were fabricated and compared utilizing both single layer graphene and few layer graphene (~5 layers). NIR-induced axial [...]

Photomechanical Response in Graphene Nanoplatelet Composites

Loomis J., King B., Burkhead T., Xu P., Bessler N., Terentjev E., Panchapakesan B., University of Louisville, US

Large light-induced reversible and elastic responses of graphene nanoplatelet (GNP) polymer composites are reported. Homogeneous mixtures of GNP/polydimethylsiloxane (PDMS) composites (0.1–5 wt%) were prepared and their near-infrared (NIR) mechanical responses studied with increasing pre-strains. Using [...]

Carbon Based Dimensional Composites

Loomis J., King B., Panchapakesan B., University of Louisville, US

Dimensional dependence of mechanical response in carbon nanostructure composites to near-infrared (NIR) light are reported. Using polydimethylsiloxane, composites were fabricated with one-dimensional multi-wall carbon nanotubes (MWCNTs), two dimensional single-layer graphene, two and a half-dimensional graphene [...]
