Polyethylene glycol (PEG) and laponite were prepared together as PCM and a multi-layer composite containing this PCM was developed, consisting of a PCM loaded layer, a nano barrier layer and a protective layer. SEM was used to observe the structure of multi-layer composites containing PCM, with better adhesion observed between the PCM loaded layer, the nano barrier layer and the protective layer. DSC revealed the melting temperature, the cooling temperature and the enthalpy of PEG and laponite as PCM. The multi-layer composite containing PCM was obtained. Laponite functionalized as a nucleating agent to accelerate the crystallization of PEG and 15wt% LP in PCM resulted in a disordered PEG molecular. The composites with more laponite had the higher thermal insulation.
