Abstract - Reinforcement, especially nano-reinforcement, is very important for rubber matrixes [1-3]. In such a case, the dispersion of nano-filler in rubber matrix and interfacial interaction between filler and rubber are two critical factors to affect the final performance of composites. It is always an interesting field to develop novel techniques to achieve fine dispersion of nano-filler and strong interfacial interaction. Recently, an universal method of preparing rubber nanocomposites has been developed in our laboratory, i.e. co-coagulating rubber latex and target filler aqueous suspension (namely LCM). In this paper, rubber-clay nanocomposites, rubber-attapulgite (AT) nanocomposites, rubber-starch nanocomposites, rubber-graphite nanocomposites, rubber-graphene nanocomposites and rubber-silica nanocomposites were prepared by LCM and their structures and properties are investigated. Compared with direct blend method, LCM can remarkably improve the filler dispersion. In addition, the designed interfacial interaction can be obtained through the in-situ modification during latex compounding. As a result, the composites prepared by LCM exhibit excellent mechanical properties. LCM is proved to be a very effective way to prepare rubber nanocomposites with many advantages, such as low cost and low pollution, etc.
