Polymerized Delamination of Clay in Polyolefins: From Efficient Intercalative Polymerization to Product-Retrievable Nanocomposite Preparation

摘要

Since the invention of nylon/clay (mostly montmorillonite,MMT) nanocomposites by Toyota researchers in the 1990s,1 the study of MMT-reinforced polymer nanocomposites has been one of the most interesting subjects in both polymer and material research fields.2 This is because the introduction of a few weight percent of nanometer-scale laminated silicate layers into a polymer matrix can drastically improve many of the polymer properties,such as modulus,strength,heat resistance,anti-flammability and anti-gas permeability,which are usually very difficult to access by traditional micrometer-scale inorganic fillers.3
