Abstract:Phase change energy storage is an effective way to solve the current energy shortage. Phase change material（PCM） has large thermal energy storage capacity during the phase change process and with the potential thermal energy storage capacity in a state close to constant temperature. Nanocellulose is a kind of material with nanometer size， high thermal stability， abundant hydrophilic hydroxyl groups and active sites on the surface， which has broad application prospects as the substrate of composite PCM. In this paper， aiming at the problems of easy leakage and unstable shape of PCM in the process of phase change， the role of nanocellulose in composite PCM was discussed and the preparation methods of PCM from nanocellulose-based aerogels， nanocellulose-based microcapsules and other nanocellulose-based composite materials were reviewed. The future research directions of nanocellulose-based composite PCM were prospected.
