1-Octadecanol@hierarchical porous polymer composite as a novel shape-stability phase change material for latent heat thermal energy storage

A hierarchical porous polymer (HPP), which was prepared by the imine condensation between pararosaniline base and 1,4-phthalaldehyde, has been used as the supporting material for novel shape-stability phase change materials (ssPCMs). With high porosity (91.9%), the hierarchical pores in the HPP supply sufficient space to adsorb 1-octadecanol, which is restricted in pores by the weak interactions such as hydrogen bonding, surface tension and...
