Novel flexible polyurethane/MXene composites with sensitive solar thermal energy storage behavior

In this study, the novel flexible polyurethane/MXene solid–solid phase change materials (SSPCMs) with improved solar-to-thermal conversion efficiency and mechanical strength were constructed using polyethylene glycol (PEG)/MXene blends and hexamethylene diisocyanate trimer (HDIT) through an efficient polyurethane reaction. The obtained SSPCMs exhibit leakage-proof properties, which can be attributed to the formed three-dimensional crosslinking...
