Graphene-Reinforced Polymer Matrix Composites

​

Invention Summary:

Despite the increasing demand for low-cost, light weight and high-performance materials across various industries, most polymer materials lack these properties. Graphene offers a promising solution by enhancing the electrical and thermal conductivity property as well as mechanical strength when added to the polymer. However, existing methods for producing graphene-reinforced polymer matrix composites remain costly and lack scalability.   

Researchers at Rutgers have developed novel methods for fabricating polymer matrix composites reinforced with graphene through in situ exfoliation of graphite within a molten thermoplastic polymer. The process applies successive shear to exfoliate graphite into single- and multi-layer graphene nanosheets that can bond with the polymer, resulting in composites with improved stiffness, strength, electrical and thermal conductivity. This method can also easily integrate other materials, such as carbon fibers, during the melt processing process to create strong polymer-carbon fiber bonds, further enhancing the mechanical performance of the composites.
