【摘要】 <正>A series of novel polyethylene glycol-silver nanowire/expanded vermiculite shape-stabilized composite phase change materials(PEG-Ag/EVM ss-CPCMs)were prepared by physical blending and impregnation method to overcome liquid leakage during phase transition and enhance the thermal conductivity of PEG.In these PEG-Ag/EVM ss-CPCMs,PEG served as the phase change material for thermal更多还原
