摘      要：Cold chain transportation is currently a hot research *** the traditional refrigeration methods lead to the consumption of large amounts of energy,the search for new energy storage materials is a major *** the present contribution,n-dodecane/PMMA microencapsulated phase change materials were prepared by suspension polymerization for ice-temperature cold chain transportation and their preparation parameters were explored using the encapsulation ratio as optimization *** results show that the n-dodecane-containing microcapsules have a maximum encapsulation ratio of 93.2%when using a core-to-wall ratio of 3:1,5%of emulsifier,30%of crosslinker,and 2000 rpm of emulsification *** phase transition temperature and enthalpy are-2℃and 195.9 kJ/kg,*** microcapsules prepared with the optimized process parameters have good microscopic morphology,high energy storage efficiency,uniform particle size and good thermal stability,making them ideal materials for cold chain transportation.
