Abstract

Na-MMT/Poly-Vinyl acetate-Acrylate (PVA) nanocomposite emulsion was prepared by in situ emulsion polymerization in the presence of exfoliated Na-MMT suspension. Effect Na-MMT content on the polymerization process and stability of the emulsion was studied. The water-proofing, thermal stability and anti-aging properties of the prepared Na-MMT/PVA composite polymer films were studied by water absorption ratio, thermo-gravimetric analysis (TGA) and anti-ultraviolet aging test. The results show that stable Na-MMT/PVA nanocomposite emulsion is obtained when the Na-MMT content is lower than 2.0wt%. TEM(Transmission electron microscopy) observation indicates that the Na-MMT/PVA composite latex has a layer-sphere combined structure. The composite polymer film presents much better water-proofing, thermal stability and anti-aging properties than the pure PVA polymer film.
