论文摘要
Micro-encapsulated phase-change materials（micro PCMs） with Na2HPO4·12 H2 O encapsulated in poly（lactic acid）（PLA） shell were prepared by a solvent evaporation–precipitation method that involves the use of a coaxial needle. The effects of PLA concentration, stirring speed, injection rate of core and shell solutions, and polyvinyl alcohol（PVA） concentration on phase change properties were investigated. The thermal properties of microP CMs were characterized by differential scanning calorimetry（DSC）. The capsules prepared under the optimal conditions are about 2 mm in diameter and show a latent heat of up to 122.2 J·g-1.
