Fabrication of polycaprolactone (PCL) graphene nanocomposites by solution intercalation

Polycaprolactone (PCL), a biodegradable polymer with poor properties, such as low glass transition temperature, low mechanical property and high permeability, restrict to use in wide range of applications. In this study, PCL hybrids with different weight percentage of graphene nanofiller by solution...
