负载相变微胶囊的纸基复合材料降温性能研究
Study on the Cooling Performance of Paper-based Composites Containing Phase Change Microcapsules
摘要
Abstract
In this study,a novel paper-based composites containing phase change microcapsules(C-PCM)was fabricated for the cooling segment of heat not burn(HNB)cigarettes.Using paper as the substrate,a coating solution was prepared by dispersing phase change mi-crocapsules(PCM)in a polyvinyl alcohol(PVA)solution,which was then applied onto the paper.Through optimization of PVA concentra-tion,phase change temperature,and coating parameters,the coating solution optimal preparation conditions were determined as:PVA solu-tion mass fraction was 5%,PCM phase change temperature was 45℃,coating solution solid content was 20%.The C-PCM prepared under this condition reduced the maximum temperature of the cigarette filter to 37.4℃,significantly outperforming commercially available HNB cigarette filters.The phase change enthalpy of C-PCM reached 120.3 J/g at this coating condition,confirming excellent heat absorption ca-pability.Additionally,C-PCM exhibits favorable tensile index(57.4 N·m/g),hydrophilicity(water contact angle 44.2°),and oil resistance.When maintaining the cooling performance of C-PCM as much as possible,adding an appropriate amount of CaCO3 thermal conductive fill-er could replace an appropriate amount of phase change microcapsules to save costs.关键词
