Abstract
. The reversible phase transition of polyethylene glycol (PEG) segments locked within the networks enables excellent smart shape memory features. Notably, the networks can undergo rearrangement through interesterification, thereby acquiring recyclability and self-healing properties. Additionally, the thermal conductivity of the matrix is enhanced through the addition of BN. It is further demonstrated that the thermally conductive PCMs retain high toughness, recyclability and shape memory features, while simultaneously exhibiting potential thermal management capabilities.
