Abstract: A continuous process for producing a surface-metalized polymer article, comprising: (a) continuously immersing a polymer article into a graphene dispersion comprising multiple graphene sheets dispersed in a liquid medium for a period of immersion time and then retreating the polymer article from the dispersion, enabling deposition of graphene sheets onto a surface of the polymer article to form a graphene-attached polymer article; (b) continuously moving the graphene-attached polymer article into a drying or heating zone to enable bonding of graphene sheets to said surface to form a graphene-covered polymer article; and (c) continuously moving the graphene-covered polymer article into a metallization zone where a layer of a metal is chemically, physically, electrochemically or electrolytically deposited onto a surface of the graphene-covered polymer article to form the surface-metalized polymer article. Step (a) may be preceded by a surface treatment of the polymer article.

Abstract: An integrated heat sink article composed of a heat collection member and at least one heat dissipation member integral to the heat collection member, wherein the heat collection member is configured to be in thermal contact with a heat source, collects heat from the heat source, and dissipates heat through the at least one heat dissipation member, and further wherein the heat sink is formed of a nano graphene platelet-reinforced composite having nano graphene platelets or sheets (NGPs) as a first reinforcement phase dispersed in a matrix material and the first reinforcement phase occupies a weight fraction of 1-90% based on the total composite weight. Preferably, these NGPs, alone or in combination with a second reinforcement phase, are bonded by an adhesive and constitute a continuous 3-D network of electron- and phonon-conducting paths.
