二氧化硅填充的甲基丙烯酸酯复合材料的动态机械性能作为温度的函数进行测量。机械性能的变化，特别是损耗角正切值的变化，与硅烷偶联剂 γ-MPS 吸附行为的变化相关。结果表明，随着硅烷覆盖率的增加，变化很小，直到化学吸附的硅烷量达到饱和并且硅烷开始物理吸附。由于增强作用，物理吸附硅烷的存在导致了巨大的差异。还表明，对于所有检查的情况，硅烷并未分散在整个基质中，因此大部分硅烷停留在界面附近。
The dynamic mechanical properties of a silica filled methacrylate compositeas measured as a function of temperature. Changes in mechanical properties, particularly in tan delta, were correlated with changes in the adsorption behavior of the silane coupling agent, γ-MPS. It was shown that there was little change with increasing silane coverage until the amount of chemisorbed silane became saturated and the silane began to physisorb. The presence of physisorbed silane caused dramatic differences, due to reinforcement. It was also shown that for all cases examined, the silane was not dispersed throughout the matrix and therefore the majority of the silane stayed in the vicinity of the interphase.
