Abstract
|
In this work, rubber composites based on bromobutyl rubber (BIIR) and ionic liquid (IL) integrated graphene nanoplatelets (GnPs) were prepared by a melt mixing technique. The IL helps to delaminate the GnP particles in the rubber matrix. The lastomeric material thus obtained shows a considerable improvement in gas barrier properties. Addition of 5 phr GnPs reduces the gas transmission rate by about 64%. Transmission electron microscopy shows better dispersion of the GnP sheets in BIIR-GnP-IL composites compared with BIIR-GnP. Wide-angle X-ray scattering experiments indicate the presence of fewer stacked GnP sheets in the BIIR-GnP composite.
