n-C20@TiO2-x相变微胶囊及其调温羽绒的制备与性能
Preparation and Properties of n-C20@TiO2-x Phase Change Microcapsules and Thermoregulated Down Feather
摘要
Abstract
The phase change microcapsule of n-C20@TiO2 with titanium dioxide(TiO2)as shell and n-eicosane(n-C20)as core was prepared through sol-gel method.The microcapsule of n-C20@TiO2-x was obtained by reduction reaction on TiO2 shell with hydrazine hydrate(N2H4·H2O)solution.Then,down feather(DF)with thermal storage and temperature regulation(n-C20@TiO2-x/DF)was fabricated by combining with n-C20@TiO2-x using waterborne polyurethane(WPU)as medium.The structural morphology and thermal properties of microencapsulated phase change materials(MEPCMs)and n-C20@TiO2-x/DF were characterized by Fourier transform infrared spectroscopy(FTIR),field emission scanning electron microscopy(FESEM),X-ray diffractometer(XRD),X-ray photoelectron spectroscopy(XPS)and differential scanning calorimetry(DSC),etc..The results showed that the particle size of n-C20@TiO2-x was about 309 nm,and heat enthalpy was increased from 80.2 J/g(n-C20@TiO2)before modification to 106.1 J/g,which exhibited good thermal stability.The heat enthalpy of obtained thermoregulated DF with 30%n-C20@TiO2-x was ca.18.7 J/g,and could still reach 10.6 J/g after 5 times of washing.It provided a strategy for the investigation of microcapsule modification and functional down feather materials,which was conducive to broaden the application of phase change materials in the traditional textile field.关键词
