Novel light reinforced material is prepared by surface modified alumina and poly (methyl methacrylate) (PMMA). The composite has a stacking structure with inorganic and organic materials each other like brick and mortar model. Moreover, the surface modified alumina has a strong interaction with organic material due to an increase in matrix wetting and matrix adhesion. The surface modification of alumina is prepared by various silane coupling agents (SCAs) in order to provide stable chemical interactions between organic and inorganic materials. The alkoxy silane on the other side of SCA reacts with inorganic material. In addition, SCAs with different terminal functional groups are employed in the surface modification of alumina, and the functional group reacts with an organic material. Through the pretreatment process generate more hydroxyl group on the surface of Al2O3 and it can make easily forming silanol with epoxy silane coupling agent. The silane coupling agent on the Al2O3 platelets were good interact with organic filler material (PMMA) and it effect to increasing mechanical strength.
