基于凹凸棒土对有机物的良好吸附性能,以凹凸棒土为吸附介质、石蜡为吸附对象,制备有机/无机复合相变材料.由于有机相变材料被吸附到微孔中,使其相变在固定的空间内进行,从而避免了材料在液相状态下的流动和渗漏问题.试验结果显示,坡缕石占80%的凹凸棒土吸附石蜡的最优质量比为2:1.DSC的测试显示,复合相变材料的焓变值与凹凸棒土和石蜡的吸附比例相关,凹凸棒土中坡缕石的含量越高,凹凸棒土的吸附能力就越强,复合相变材料的焓变值也就越大.温度循环试验的结果显示,复合相变材料具有良好的储(放)热性能,在环境温度上升和下降的过程中,能够储存和释放热量,这不仅增加了环境温度的惰性,也使能量能够在不同的时间和空间进行迁移,从而达到一定的节能效果.
