A kind of heat energy storage microcapsule was prepared using melamine formaldehyde resin as shell material and the compactibility of the shell was investigated.The core is a phase change material,which melts at 24 ℃ and the phase transition heat of which is 225.5 J/g.The surface morphological structure was examined by means of scanning electron microscopy.The penetrability of the microcapsule was characterized in ethyl alcohol (ρ=0.97 g/mL) by means of 722 spectrophotometer.The strength of shell was evalua...
