Controlled heat release of new thermal storage materials: the case of polyethylene glycol intercalated into graphene oxide paper

[摘要]：Brick-and-mortar microstructures of graphene oxide-polyethylene glycol (PEG) composite papers were easily prepared with large area. The freezing point of the PEG intercalated into the shaped composite paper could be successively decreased down to room temperature, while the melting point was kept constant with that of bulk PEG, which means controlled heat release was thus achieved.
