Characterization and Preparation of Epoxy Resin/Zeolite Nanocomposite

This paper proposes a new method to synthesize the epoxy resin/zeolite nanocomposite. In this method, zeolite was previously treated with sodium nitrate, and organized with ceyltrimethyl ammonium bromide. Epoxy resin was interposed in the cavity of zeolite and polymerized in situ. Then, the polymer mixtures were solidified by pp' diaphenyl methane to prepare for nanocomposite. The synthesis condition such as mixing temperature, mixing time and concentrations are discussed extensively, and the epoxy resin/zeolite nanocomposite was characterized by XRD and TEM. This composite is found to be formed by the nanometer aggregated particles, ranging from 50 to 60 nm in diameter based on the analysis of the TEM image. The epoxy resin/zeolite nanocomposite exhibits dramatic increases in their mechanical properties, which can be used in engineering plastic and high quality adhesive.
