Abstract: Layered silicate clay has attracted great attention in improving the properties of silicone rubber due to its unique nano-layered structure, resourceful, low-cost and pollution-free characteristics. Recent advances in the mechanism and properties of silicone rubber nanocomposite materials modified with layered silicate clay including 2∶1 structure such as montmorillonite, attapulgite and 1∶1 structure such as kaolinite and halloysite are reviewed. In this article, the emphasis of the recent studies is pointed out to be the improvement of the performance of silicone rubber. And uniform dispersion of the layered silicate clay particles into silicone rubber matrix is crucial and challenging due to the disparity in hydrophilic and hydrophobic character of the layered silicate clay and the rubber matrix. The development of layered silicate clay/silicone rubber nanocomposites is prospected in order to provide reference for the deep-digging of the modified layered silicate clay and silicone rubber nanocomposites with high performance.

Key words: layered silicate clay, silicone rubber, nanocomposite, dispersion, montmorillonite, attapulgite, kaolinite, halloysite
