| 英文摘要 | for heat energy storage application, polyurea microcapsules containing phase change material, n-eicosane, were synthesized by interfacial polymerization method with toluene -2,4-diisocyanate (tdi) and ethylene diamine (eda) as monomers in an emulsion system. poly (ethylene glycol) octyl-phenyl ether (op), a nonionic surfactant, was the emulsifier for the system. the experiments indicated that tdi was reacted with eda in a mass ratio of 1.9 to 1. the sizes of microcapsules were analyzed with tem and laser particle analyzer, which showed the empty microcapsules were about 0.2 mu m and those containing n-eicosane were 2-6 mu m. ftir spectra proved the formation of wall material, polyurea, from the two monomers, tdi and eda. encapsulation efficiency of n-eicosane was about 75%. microcapsules of n-eicosane melted at a temperature close to that of n-eicosane, while its stored heat energy varied with the amount of core material n-eicosane. thermogravimetric analysis revealed that the core material n-eicosane, micro-n-eicosane, and wall material polyurea could withstand temperatures up to 130 degrees c, 170 degrees c, and 270 degrees c, respectively. |
