PVC nanocomposite manufacturing technology and applications

摘要

The present invention relates to a process and a product of forming polymer (especially PVC) nanocomposites with a variety of nanofillers. The present invention provides a method for forming a polymer nanocomposite, comprising powder mixing a composition comprising polymer resin, a nanofiller, and a coupling agent for a residence time of about 4 to about 8 minutes to form a dry blend and extruding the dry blend in an extrusion process. Additionally, the present invention relates to a polymer nanocomposite formed by a process, comprising powder mixing a polymer resin, a nanofiller, and a coupling agent for a residence time of about 4 to about 8 minutes to form a dry blend and extruding the dry blend in an extrusion process to achieve homogeneous dispersion of nanofillers in the polymer matrix.
