Graphene-Polymer Composites

Nanotube and Graphene Polymer Composites for Photonics and Optoelectronics

Polymer composites are an attractive near-term means to exploit the unique properties of single wall carbon nanotubes and graphene. This is particularly true for composites aimed at photonic and optoelectronic applications, where a number of devices have already been demonstrated. These include transparent conductors, saturable absorbers, electroluminescent and photovoltaic devices. Here, we pr...

Graphene and Polymer Composites for Supercapacitor Applications: a Review

Supercapacitors, as one of the energy storage devices, exhibit ultrahigh capacitance, high power density, and long cycle. High specific surface area, mechanical and chemical stability, and low cost are often required for supercapacitor materials. Graphene, as a new emerging carbon material, has attracted a lot of attention in energy storage field due to its intrinsic properties. Polymers are of...

Low percolation threshold of graphene/polymer composites prepared by solvothermal reduction of graphene oxide in the polymer solution

Graphene/polyvinylidene fluoride (PVDF) composites were prepared using in-situ solvothermal reduction of graphene oxide in the PVDF solution. The electrical conductivity of the composites was greatly improved by doping with graphene sheets. The percolation threshold of such composite was determined to be 0.31 vol.%, being much smaller than that of the composites prepared via blending reduced gr...

Polymer Microvascular Network Composites

Microvascular networks show promise for applications such as selfhealing, self-cooling, and structural damage sensing. Fluid-filled micro-scale channels have been investigated extensively in the field of microfluidics, but threedimensional networks in polymeric structural materials have been achieved only recently. The purpose of microvascular network integration is to provide a vehicle for the...
