Abstract:
1. A method for forming a polyvinyl chloride-nanoparticle composite, the method comprising steps: (a) heating particles of a polyvinyl chloride (PVC) polymer to a temperature at or above a fusion point of the PVC, thereby fusing the PVC particles to form fused PVC particles having a size less than 100 nm; (b) blending a filler comprising nanoparticles into the fused PVC particles; and, (c) heating and mixing the blend of the fused PVC particles and the filler until the fused PVC particles are eliminated, thereby forming the polyvinyl chloride-nanoparticle composite, the composite comprising (i) a matrix comprising the PVC polymer and (ii) the filler dispersed throughout the matrix.
