Microencapsulation of phase-change materials has been studied for application to thermal energy fields such as heating and air conditioning of buildings, thermal insulation materials, thermal adaptable fibers. The functions and characteristics of microcapsules depend on the properties of the shell. So we can control the release and protection of the core materials by varying the characteristics of polymerized shell. Microcapsules containing phase-change material for thermal adaptable fiber application were synthesized and characterized. The microcapsules of about 1μm in diameter were prepared using an interfacial polycondensation method with toluene-2,4-diisocyanate (TDI) and diethylenetriamine (DETA) as monomers in an emulsion system. Octadecane was used as a phase-change material and NP-10 which is nonionic surfactant, was used as an emulsifier. |
