摘要: Highly filled dielectric polymer nanocomposites with high constant nanoparticles (e.g., BaTiO3) have promising application in many fields such as energy storage. The effectiveness of these to increase the and density resulting has already been demonstrated. However, role interface between matrix on thermal expansion, storage breakdown strength-the three parameters that are important for practical nanocomposites, not systematically documented. In this contribution, we investigated effect six kinds nanoparticle surface chemistry processing, coefficient strength highly epoxy/BaTiO3 nanocomposites. It was found all aspects, particular processability associated chemistry. Combining processability, conclude functionalized by silane coupling agents terminal groups capable reacting epoxy more suitable preparing
