Microencapsulation of n-eicosane as Energy Storage Material Synthesized by Interfacial Polymerization;
界面聚合法制备正二十烷微胶囊化相变储热材料(英文)
Polyurea microcapsules containing a phase change material,n-eicosane,were synthesized by means of interfacial polymerization method with toluene-2,4-diisocyanate(TDI) and 1,6-hexane diamine(HDA) as the monomers in an emulsion system.
用界面聚合的方法,以甲苯-2,4-二异氰酸酯(TDI)和己二胺(HDA)为反应单体,非离子表面活性剂聚乙二醇壬基苯基醚(OP)为乳化剂,合成了正二十烷为相变材料的聚脲包覆微胶囊。
Stable icosahedral Zn_(60)Mg_(30)Y_(10) quasicrystals was prepared by as-cast method.
实验结果发现:Mg Zn Y三元合金在室温冷却过程中,准晶相直接从液相形核、长大;当合金成分为Mg74Zn25Y1时,凝固组织为MgZn基体相、析出相为α Mg固溶体及二十面体Mg30Zn60Y10准晶相;当x(Y)为2%、3%时,合金中出现共析组织。
