Insitu dispersion of modified nano alumina in tetra glycidil / epoxy resin

Surface organic modification of nanosized alumina particles and insitu polymerization is an effective way to improve its dispersion in polymer and to enhance the mechanical properties of polymer nanocomposites. Different alumina nanoparticles were incorporated in insitu polymerization of tetra functional epoxy resin. The SEM analysis showed the positive effect of silane modification of alumina nanoparticles in dispersion into polymeric matrix, with little effect on polymerization efficiency.the measurement on EEW showed about 5% enhancement after addation on each alumina nanoparticless
