研究十六烷基三甲基溴化铵(CTMAB)、十四烷基三甲基溴化铵(TTAB)、十二烷基三甲基溴化铵(DTMAB)等不同碳链长度的季铵盐对所制备的有机膨润土(001)面层间距的影响,同时研究CTMAB不同掺量对所制备的有机膨润土(001)面层间距的影响.通过X射线衍射(XRD)、热重(TG)、红外光谱(IR)等测试手段对有机改性膨润土进行结构和性能的表征.实验结果表明,季铵盐碳链长度的增加和掺量的增大都可以使得膨润土(001)面层间距增大,确定了有机改性剂的最佳掺量和碳链长度.制备的有机膨润土由于其层间较长的烷基链的存在,完成了膨润土的层间由亲水性向亲油性的转变,为有机膨润土在相变储能建筑材料、油漆、涂料等领域的应用奠定了基础.
