SURFACTANT-FREE SYNTHESIS AND FOAMING OF LIQUID BLOWING AGENT-CONTAINING ACTIVATED CARBON-NANO/MICROPARTICULATE POLYMER COMPOSITES

摘要

Exemplary embodiments of the present invention relate to polystyrene and/or thermoplastic polymer or polymer blend composite foam or a foamable polymeric material precursor, which contains activated carbon and/or at least one of 1 -dimensional, 2-dimensional, and 3-dimensional nano/micro-materials in polystyrene and/or thermoplastic polymer and/or polymer blend matrix to carry a co-blowing agent such as water without using any surfactant-like molecules and/or polymers, having or adapted to have the properties of low density, high-R value, good mechanical properties, and fire retardance thereof. Exemplary embodiments of the present invention include various manufacturing methods that may be employed including, but not limited to, extrusion, batch molding, and injection molding. One example includes synthesis and CO2 and water-based extruded foaming of such a material.
