| 摘 要： | 利用真空吸附法制备了有机无机复合相变材料,采用差示扫描量热仪(DSC)和扫描电镜进行测试,结果表明,此复合材料调温功能稳定,有机相变材料被无机多孔材料吸附到孔道中,并且相变材料在孔道中分布均匀.经热重法分析,此真空吸附方法制备的复合相变材料在100℃以下相变性能稳定,不会对环境造成污染.

| Abstract: | Organic/inorganic composite phase change material(PCM)is prepared using the method of vacuum absorption and tested by means of differential scanning calormetry(DSC)and scanning electron microscopy(SEM).The testing results show that organic PCM is absorbed into the holes of inorganic carriers completely and distributed evenly with stable performances.It is concluded that the composite PCM has steady temperature-adjust function and the preparation method is acceptable. |
