%X A novel epoxyresin/MCM-41 nanocomposite modified by coupling agent was prepared by solution blending. The influences of the amount of coupling agent and the medium modification on the disperse properties and mechanical properties were investigated. The results showed that the novel nanonetwork composite with the monodisperse, nanosized mesoporous MCM-41 particle strenghened is prepared at the suitable amount of coupling agent and the suitable medium. -(CH2)3-NH2 group of silane coupling agent not only gets into the modified inner wall of mesoporous MCM-41,but also makes MCM-41 remain its ordered pore structure. Because the chain of epoxy resin links with the inner and outer of the modified MCM-41 through chemical bond, MCM-41 particle can disperse evenly in the matrix. Compared with the matrix, the tensile strength and the Young's modulus of the composites are improved by 69% and 90%, respectively,
