In recent years, it is important to develop efficient multifunctional construction materials under building energy consumption increased continuously. In this study, paraffin/ polyimide aerogel composite phase change materials (CPCMs) with excellent thermal management and hydrophobic thermal insulation by simple melt impregnation method were prepared. Among them, P-P75O25 (n(BPDA-PPD):n(BPDA-ODA)=75:25) CPCM shows excellent comprehensive performance. Its latent heats are 100.98 J/g and 96.21 J/g and enthalpy efficiency are 93.52% and 92.31% during melting and freezing process, respectively. After 200 thermal cycles, the enthalpy loss rate of melting and freezing are 4.25% and 0.73%. At the same time, superior hydrophobic and antimicrobial resistance are verified. All results indicate that P-P75O25 has great potential as a green construction material.
