纳米银负载三聚氰胺泡沫基相变复合材料的一步法制备及结构与性能
Structure and Properties of One-step Prepared Nano-silver Supported Melamine Foam Based Phase Change Composites
摘要
Abstract
The lightweight and flexible melamine foam(MF)served as the matrix was placed in a reaction solution consisting of ethylene glycol(EG),silver nitrate(AgNO3),polyvinylpyrrolidone(PVP),and copper chloride(CuCl2).Under high temperature conditions,a redox reaction occurred,resulting in the formation of nano-silver(Ag)on the foam skeleton.Subsequently,the phase change composites were fabricated by encapsulating lauric acid(LA)in foam matrix through vacuum impregnation method.The morphology,structure,and thermal properties of the phase change composites were investigated by scanning electron microscope(SEM),X-ray diffractometer(XRD),differential scanning calorimeter(DSC),and infrared thermal imager,respectively.The results indicated that when the concentration of AgNO3 was 4 mg/mL,nano-Ag was uniformly and densely deposited on the surface of the MF skeleton,and there were two forms of Ag,nanoparticles(AgNPs)and Ag nanowires(AgNWs),presented simultaneously.The latent heat of phase change composites could reach up to 144.0 J/g,and the thermal efficiency exceeded 80 % ,demonstrating superior temperature regulation and heat storage capability.This paper provides a novel strategy for the fabrication of phase change composites with outstanding comprehensive property,thereby being in favor of broadening their potential applications.关键词
