摘　　要：利用不锈钢高压釜产生压力,实现了DMSO快速插层高岭土,相比常规方法,缩短了反应时间。室温外电场作用下,高岭土-DMSO插层复合物表现了铁电性,自发极化强度(Ps)约为0.14μC/cm2,偶极反转可能来自DMSO分子在层间的相对位移。By means of autoclave improving reaction system pressure, the kaolinite - DMSO intercalated compound was syn- thesized in 6 hours, which takes much shorter time than other common ones. This intercalated compound appears typical ferroelec- tric at room temperature and the spontaneous polarization （Ps） is roughly estimated as 0.14μ C/cm2. It is possible dipole reversal of DMSO molecules by way of the orientation reversal of DMSO molecules under ac electric field.
