Preparation and Characterization of Polycaprolactone / Graphene / Zinc Oxide Composites

Abstract:

Biodegradable composite from polycaprolactone (PCL) and Graphene/zinc oxide (Graphene/ZnO) is studied. The Graphene/ZnO content is at 0.5%, 1.5% in PCL. Neat PCL and composites were characterized by microstructure, mechanical properties and thermal properties. Scanning electron micrographs show that the additive has agglomerated in PCL/Graphene/ZnO. Agglomeration of the filler results in reduced tensile properties of the composite. The result from XRD indicates Graphene/ZnO can improve the crystallinity of PCL. According to the results of buried soil test and analysis, Graphene/ZnO can reduce the biodegradation rate of PCL and make the material more durable. This new biodegradable composite material can be used as a new environmentally friendly material.
