High-performance fluoroelastomer-graphene nanocomposites for advanced sealing applications

High-performance sealing materials that can guard key components against high pressure gases and liquid chemicals while withstanding mechanical deformation are of utmost importance in a number industries. In this present work, graphene nanoplatelets (GNPs) were introduced into fluoroelastomer (FKM) matrix to improve its barrier properties test suitability for applications. Nanocomposites filled with different loadings GNPs prepared compared their counterparts loaded carbon black (CB). dispersed homogeneously degree in-plane alignment. The tensile the FKM improved significantly by addition GNPs. Micromechanical modelling based on shear-lag/rule-of-mixtures theory was used analyse reinforcing efficiency Upon GNPs, elastomer able swell anisotropically liquids, fact be tune swelling terms gas permeability, modification well-established Nielsen's CO2 permeability bulk composite samples. mechanical, thermal at relatively low filler loadings, reveal FKM/GNP nanocomposites produced very promising use advanced
