Abstract

In this work, we develop fluorosilicone elastomer (FSE) compounds with advanced properties by incorporating graphene oxides functionalized with vinyltrimethoxysilane (GO-V) and allyl isocyanate (GO-A). The morphology and structure of the graphene oxides were characterized confirming the successful functionalization, with contents of functional groups of 9.80 and 3.60% for GO-V and GO-A, respectively. The strong elastomer-graphene oxide interaction accelerates the crosslinking reaction and causes an important enhancement of the mechanical properties and thermal stability of composites. In addition, the swelling resistance to acid, base, and organic solvents is improved by more than 30%. These functional properties make FSE/GO composites a promising new class of advanced materials, expanding their potential application in edge technologies, spanning the manufacture of automotive components, aerospace and aviation parts, oil, gas, and petrochemical components, among others, particularly, seals, gaskets, valves and pipelines, or different components exposed to oil or solvent and high temperatures that require higher performance compared to conventional FSE products.
