3D Graphene Foam Reinforced Flexible Polymer Composites
Abstract
The proposed work will synthesize Polymer/GrF composite by dip coating and electrostatic spray deposition. Polymer/foam ratio will be varied over spatial densities to tailor the flexibility, strength, and conductivity. Studies will investigate the wetting behavior of the polymer matrices (polyethylene, polyurethane and silicone) over graphene foam to determine interfacial characteristics and interphase formation, if any. In-situ SEM analysis will be done within the chamber of a dual beam focused ion beam (FIB) to facilitate real time understanding of deformation mechanisms under tension, compression and bending. Nano DMA (micro Newton load) and conventional DMA (several Newton load) experiments will be conducted to evaluate effect of 3D Graphene foam on the shock absorption/damping behavior (Tan δ) of the composite. Electrical and thermal properties will be measured as a function of mechanical strain by 4-point probe and flash diffusivity respectively. Modeling of overall effective mechanical and thermal properties of composite will be done using object orient finite (OOF) element method.
