摘要
Abstract
Polystyrene/paraffin phase-change composite foam(EPSPW)was prepared through encapsulating paraffin into the pores of the foam using an emulsion-templating method.SEM observation indicated that the porosity of EPSPW ranged from 85 to 92 vol%and the pore size ranged from 3.5 to 10 μm with a narrow distribution.When the paraffin con-tent was 30 wt%,EPSPW exhibited excellent shape stability without any leakage of paraffin,and its loading of paraffin was 33 times as great as its own mass.The leaching test results indicated that the mass loss rate of the sample was only 3 wt%at temperatures above the melting point of paraffin.EPSPW presented a melting enthalpy of 32 J/g,which was much higher than that of directly foamed phase-change foam materials(mostly around 15～20 J/g).In addition,EP-SPW exhibited good cycle stability over 50 heating/cooling cycles.关键词
