| 摘 要： | 本文通过将纳米氧化锌（ZnO）颗粒加入熔融的石蜡（PW）并进行搅拌和超声制备了一种纳米ZnO／PW复合相变储能材料。为使纳米氧化锌在基体物质中分散均匀，在制备过程中使用了搅拌和超声以制备均匀的复合材料。使用扫描电镜观察其微观结构表明氧化锌在石蜡中分散良好。对所得ZnO／PW复合相变材料的相变温度、相变焓及导热系数等热物...

| Abstract: | Paraffin wax(PW) based phase change composites were prepared by adding ZnO nanoparticles into melting PW with intensive sonication.The composites appear homogeneous in the SEM images.The composites have substantially higher phase change temperature and latent heat than the matrix does.The thermal conductivity of the composites did not change significantly with the increasing temperature away from the phase change temperature.The composites enhance the thermal conductivities compared to pure PW in both solid... |
