A microcapsule with intelligent photochromic and energy storage temperature adjustment function has been prepared with melamine‐formaldehyde as wall material via an in situ polymerization method ,and the pho‐tosensitive color material which has been dissolved in phase change materials of fatty acid ester was chosen as the core material .DSC ,TGA ,SEM ,particle size analysis and color measurement were used to characterize the prepared microcapsules .The results indicate that the microcapsules had good formation with smooth and com‐pact spherical surfaces ,and their particle size was centralized in 3‐4μm .Moreover ,the microcapsules exhibited excellent performance on photochromic energy storage and temperature adjustment .The rise and cooling phase transition temperature were found to be 27 0. and 20 2. ℃ ,and the molten phase transition enthalpy and solidifi‐cation phase change enthalpy were calculated to be 68 1. and 86 2. J/g ,respectively .
