Sulphur prevulcanised natural rubber latex (PVNRL) nanocomposite was produced by mixing dispersions of layered silicates with prevulcanised latex. In this study layered silicates such as bentonite (natural) and fluorohectorite (synthetic) were used in addition to a non-layered amorphous filler (English Indian clay) as reference material. After compounding the layered silicate dispersions with PVNRL, films were prepared by casting. The vulcanised films of PVNRL nanocomposites were subjected to mechanical, swelling, X-ray diffraction and transmission electron microscopic studies. In all respects, layered silicate nanocomposites registered superior properties compared to the reference material. This was explained to be due to the intercalation/exfoliation of the silicate layers by natural rubber. It was found that the fine silicate layers formed a skeleton network structure (house of cards) in the vulcanisate.
