Customer Service1. Introduction Phase change fibers, fibers that contain phase change materials (PCMs), can help create a comfortable microclimate with almost constant temperature through storing and releasing a large amount of thermal energy during the reversible phase-transition of PCMs [, , ].

To meet the demands of the global energy transition, photothermal phase change energy storage materials have emerged as an innovative solution. These materials, utilizing various photothermal conversion carriers, can passively store energy and respond to changes in light exposure, thereby enhancing the efficiency of energy systems.
