COMPATIBILIZATION OF POLYMER CLAY NANOCOMPOSITES

摘要

A polymer nanocomposite contains layered clay dispersed in a polymer matrix together with compatibilizers for the clay and polymer matrix. The compatibilizers are a combination of two or more graft polymers. One graft polymer has high functionality and short chain length and another graft polymer has low functionality and long chain length. Such polymer nanocomposites have improved dispersion and better strength and modulus, while maintaining good toughness and impact strength. The polymer nanocomposites are particularly useful in applications where good mechanical performance and light-weight are of importance.
