Ultra Fast Microwave Assisted Synthesis of Phase Change Energy Storage Nanocapsules
In recent years,how to effectively improve energy utilization efficiency and the development of new energy storage materials have become current research hotspots.Based on microwave assisted polymerization,by introducing microwave sensitizers and using orthogonal experiments,ultra fast polymerization of phase change energy storage nanocapsules was achieved.The polymerization time was shortened to within 5 min,and the reaction temperature was reduced to 40~60℃,achieving low-cost and ultra fast green preparation of phase change energy storage nanocapsules.By utilizing DLS,SEM,DSC,and TGA characterization,it was found that the optimal conditions were as follows:ultrasound power 40%,ultrasound time 1 min,and microwave speed 400 r·min-1.The resulting nanocapsules were spherical in shape with an average particle size between 70 nm and 307 nm,exhibiting good thermal properties,crystallization behavior,thermal stability,and the coverage rate of 64.69%,providing favorable conditions for their large-scale production.
