A Raman Spectroscopic Analysis of Polymer Membranes with Graphene Oxide and Reduced Graphene Oxide

Nowadays, despite significant advances in the field of biomaterials for tissue engineering applications, novel bone substituents still need refinement so they can be successfully implemented into medical treatment fractures. Generally, a scaffold made synthetic polymer blended with nanofillers was proven to very promising biomaterial engineering, however choice components said remains questionable. The objects presented study were composites consisting poly(ε-caprolactone) (PCL) and two types graphene materials: oxide (GO) partially reduced (rGO). technique choice, that used characterize obtained composites, Raman micro-spectroscopy. It revealed composite PCL/GO differs substantially from PCL/rGO composite. incorporation GO particles influenced structure organisation polymeric matrix more significantly than rGO. crystallinity parameters confirmed level is generally higher membrane comparison (and even raw PCL) leads conclusion acts as nucleation agent enhancing crystallization PCL. Interestingly, characteristics studied nanofillers, example: (D/G ratio) in-plane size nano-crystallites (La) almost do not differ. However, have an ability influence differently.
