Title Improved gas barrier properties of ionic liquid integrated graphene nanoplatelets/Bromobutyl rubber composites

Abstract In this present work rubber composites based on bromobutyl rubber (BIIR) and ionic liquid (IL) integrated graphene nanoplatelets (GnP) have been prepared by a melt mixing technique. The IL helps to delaminate the GnP particles in the rubber matrix. The elastomeric material thus obtained shows a considerable improvement of gas barrier properties. Addition of 5 phr GnP reduces the gas transmission rate by about ~64 %. The transmission electron microscopy shows a better dispersion of the GnP sheets in the BIIR-GnP-IL as compared to BIIR-GnP. The wide angle x-ray scattering experiment indicates a presence of a lower number of stacked GnP sheets in the BIIR-GnP composite.
