Graphene oxide/polyurethane-based solid–solid phase change materials with enhanced mechanical properties

Graphene oxide (GO) crosslinked Polyurethane-based phase change materials were synthesized in-situ polymerization. The system exhibited excellent form-stability owing to the synergistic effect of GO and polyisocyanate. The crystallization temperature of the system increases with the incorporation of GO as the heterogeneous nucleation effect. The mechanical properties have been greatly enhanced.
