- •
Four crosslinking β-CD/MDI/PEG copolymers were synthesized as solid–solid PCMs.
- •
The copolymers have spherocrystal morphology with smaller size than that of PEG.
- •
The crosslinking density of the copolymers effects their phase change properties.
- •
The copolymers have high phase change enthalpy and good thermal reliability.
