Small angle neutron scattering studies on RGO incorporated PVB matrix nanocomposites

Abstract

Given the importance of PVB in laminates, it is imperative that research be carried out on the surface and structural properties of PVB and its composites. In this paper the authors are reporting the preparation and characterization of Reduced Graphene Oxide (RGO) reinforced Polyvinyl Butyral (PVB) Matrix based nanocomposites. Solution casting technique is used to prepare the Nanocomposite films in Teflon Petri dishes at ambient temperature. Small-angle neutron scattering (SANS) and transmission electron microscopy (TEM) were employed to study the surface and structural features of the samples. The scattering data shows power law behavior in the low Q region, suggesting the presence of surface fractal kind of structure. The radius of gyration Rg of pure PVB and RGO incorporated (0.5 wt% and 1.0 wt%) nanocomposites are measured to study the core shell structure formation among the RGO and PVB. The Dynamic light scattering (DLS) and Zeta potential studies are performed to find Hydrodynamic radius and Zeta potentials of individuals and Nanocomposites to know the information about the stability and core shell structure.
