Abstract

A method for continuously producing a composite material is disclosed. In some implementations, the method includes supplying a thermoplastic resin having an initial density, mixing polypropylene-graft-maleic anhydride (PPgMA) formed of a plurality of interconnected PPgMA molecules throughout the thermoplastic resin, distributing a plurality of carbon particles throughout the thermoplastic resin and the plurality of interconnected PPgMA molecules, and forming, by rotational molding, the composite material based on a combination of the thermoplastic resin, the PPgMA, and at least some of the plurality of carbon particles.
