    • The invention relates to a preparation method of a polymeric phase-change material, comprising: using 1, 2 or 3 of (meth)acrylate poly(ethylene glycol) n-alkyl ether ester as a raw material, wherein the (meth)acrylate poly(ethylene glycol) n-alkyl ether ester has a structural general formula of CH2═C(CH3)—COO(CH2O)mCnH2+1 or CH2═CH—COO(CH2CH2O)mCnH2+1, m=1 to 100, and n=10 to 50; washing the raw material with a solution of sodium hydroxide, potassium hydroxide, sodium carbonate or potassium carbonate having a mass percentage of 1% to 10% to remove a polymerization inhibitor, and subjecting reduced-pressure distillation, and then to a polymerization reaction by adopting one of the following process; 1. polymerization reaction initiated by irradiation; 2. polymerization reaction initiated by an initiator; 3. polymerization reaction in a solvent; after the polymerization reaction is completed, adding a precipitating agent to precipitate the polymeric phase-change material from the solution, and then washing with deionized water and dried, to obtain a polymeric phase-change material as a powder to block.
    • 本发明涉及聚合相变材料的制备方法,其包括:使用1,2或3种(甲基)丙烯酸酯聚(乙二醇)正烷基醚酯作为原料,其中(甲基)丙烯酸酯聚 (乙二醇)正烷基醚酯具有CH 2 = C(CH 3)-COO(CH 2 O)m C n H 2 + 1或CH 2 = CH-COO(CH 2 CH 2 O)m C n H 2 + 1,m = 1〜100的结构通式,n = 10〜50; 用质量百分比为1%至10%的氢氧化钠,氢氧化钾,碳酸钠或碳酸钾的溶液洗涤原料以除去阻聚剂,进行减压蒸馏,然后通过采用聚合反应 以下过程之一; 1.通过照射引发聚合反应; 由引发剂引发的聚合反应; 3.在溶剂中进行聚合反应; 聚合反应完成后,加入沉淀剂从溶液中沉淀聚合物相变材料,然后用去离子水洗涤并干燥,得到聚合物相变材料,以粉末形式封闭。
