同轴静电喷雾技术制备相变微胶囊及其性能研究
Preparation and Properties of Phase Change Microcapsules by Coaxial Electrostatic Spray Technology
摘要
Abstract
The technology of energy storage and heat energy utilization is of great significance to human sur-vival and development,and has been widely concerned by researchers.The preparation of heat-storage and tem-perature-regulated textile materials by the combination of phase change microcapsules and fabrics has become a research hotspot in recent years,but the efficient preparation methods and application technology of microcapsules still need to be further developed and optimized.In this paper,n-octadecane and polyurethane were selected as phase change and coating materials respectively and coaxial electrostatic spray technology was adopted to prepare the phase change microcapsules with excellent heat storage and temperature regulation properties.The effects of different wall material concentrations,electric field intensities and core wall ratios on the structure and properties of microcapsules were investigated to optimize the preparation technology.The results show that under the condi-tions of PU concentration of 5%wt,wall material concentration of 7.5%wt,voltage of 10 kV,core wall extru-sion rate ratio of 1∶5,the prepared phase change microcapsules have complete structure,uniform size and good dispersion.The average particle size is 620 μm and the yield is 60.33%.The enthalpies of melting and crystal-lization are 91.25 J/g and 95.28 J/g respectively,and the phase change microcapsule has better heat storage properties,which is suitable for the development of heat-storage and temperature-regulated textile.关键词
