本研究研究了锂皂石与单烷氧基硅烷（二甲基辛基甲氧基硅烷）的边缘改性。研究了超声波、老化时间和硅烷浓度对所得材料的影响。甲硅烷基化粘土通过 XRD、IES、TGA 和 Si NMR 进行表征。通过增加硅烷与粘土的比例、对反应混合物进行超声处理以及将反应混合物老化不超过24小时来增加接枝硅烷的量，以避免由于平衡效应而去除接枝硅烷。 (c) 2008 Elsevier Inc. 保留所有权利。
This study examines the edge modification of laponite, with a monoalkoxy silane, dimethyl-octylmethoxysilane. The influence of ultrasonics, aging time and silane concentration on the resultant materials is examined. The silylated clays are characterized by XRD, IES, TGA, and Si NMR. The amount of grafted silane was increased by increasing the ratio of silane to clay, sonication of the reaction mixture and ageing the reaction mixture for no more than 24 h to avoid removal of grafted silane due to equilibrium effects.
