两种硅烷偶联剂（SCA）用于处理氧化铝纳米粒子，以改善纳米粒子分散到聚合物基体中。[3-（2-氨基乙氨基）-丙基]-三甲氧基硅烷[反应性硅烷偶联剂（RSCA）]能够与增强剂（氧化铝纳米颗粒）和环氧树脂基体形成共价键，而甲基丙烯酸3-（三甲氧基甲硅烷基）丙酯（非反应性SCA）不能与环氧树脂共价相互作用。通过共价键的填料-基质相互作用的加强导致改善的弯曲强度，应变，特别是，耐磨性。的磨损率和重量损失的RSCA处理的氧化铝纳米颗粒复合材料是最好的复合材料样品中的调查和等于这些净环氧树脂基体。这种改进是由于更好的纳米颗粒分散，这是氧化铝纳米颗粒的SCA处理的结果。© 2006 Wiley Periodicals，Inc.应用聚合物科学杂志101：4410-4417，2006
Two silane coupling agents (SCAs) were used to treat alumina nanoparticles to improve nanoparticle dispersion into the polymer matrix. [3-(2-Aminoethylamino)-propyl]-trimethoxysilane [a reactive silane coupling agent (RSCA)] was able to form covalent bonds with both the reinforcing agent (alumina nanoparticles) and the epoxy matrix, whereas 3-(trimethoxysilyl) propyl methacrylate (a nonreactive SCA) could not covalently interact with the epoxy resin. The strengthening of the filler–matrix interactions by means of covalent bonds resulted in improved flexural strength, strain, and especially, wear resistance. The wear rate and the weight loss of the RSCA-treated alumina nanoparticle composite were the best among the investigated composite samples and equal to these of the neat epoxy matrix. This improvement was due to better nanoparticle dispersion, a result of the SCA treatment of the alumina nanoparticles. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 101: 4410–4417, 2006
