摘要
以木质素为原材料和介孔分子筛(SBA-15)为模板制备木质素基有序多孔碳(MC),采用真空浸渍法负载相变材料聚乙二醇(PEG),制备出木质素基有序多孔碳复合相变材料(MC/PEG)。通过SEM、XRD、FT-IR以及DSC等方法对其结构表征及性能测试。结果表明,MC的最大负载量可达75%,其相变焓值为89.7 J·g^(-1)。在负载量为60%时,MC/PEG复合相变的热导率可达0.5029 W/mK,较纯PEG提升了50.3%。将MC/PEG复合相变材料利用涂层法制备了相变调温棉织物,经过红外热成像分析后可以发现相较棉织物,相变调温棉织物拥有良好的调温性能。
Lignin-based ordered porous carbon(MC)was prepared using lignin as the raw material and mesoporous molecular sieve(SBA-15)as the template.The lignin-based ordered porous carbon composite MC/PEG was prepared by vacuum impregnation with polyethylene glycol(PEG).Its structure and properties were characterized by SEM,XRD,FT-IR and DSC methods.The results showed that the maximum loading of MC was up to 75%and the enthalpy of phase change was 89.7 J/g.When the loading was 60%,the thermal conductivity of MC/PEG was up to 0.5029 W/mK,which was 50.3%higher than that of pure PEG.The composite phase change material coated cotton fabric was prepared by the MC/PEG coating method.After infrared thermography analysis,it can be found that the coated cotton fabric had good temperature regulation performance compared with the cotton fabric.
