Recent Advances in Organic/Composite Phase Change Materials for Energy Storage

Abstract

Phase change materials (PCMs) store and release energy in the phase change processes. In recent years, PCMs have gained increasing attention due to their excellent properties such as high latent heat storage capacity, appropriate solid-liquid phase change temperature, thermal reliability, and low cost. Herein, classification, characteristics, and evaluation criteria of organic/composite PCMs are systematically illustrated, and some typical preparation methods are introduced, such as in-situ polymerization, interfacial polymerization, spray drying method, porous materials adsorption method, sol-gel method, meltimpregnated and mixing method, electrospinning method, vacuum infiltration and ultrasonic method are introduced. In addition, this review presents some applications of PCMs in the utilization of solar energy, building materials, air conditioning, industrial waste heat recovery, and military camouflage and stealth. Finally, the development tendency of PCMs is discussed.

Promoting healing progress in polymer composites based on Diels‐Alder reaction by constructing silver bridges

“…Polymer materials have been used widely in many fields, including energy storage and conversion, 1‐6 electromagnetic interference (EMI) shielding, 7 thermal management, 8,9 sensors, 10,11 cryogenic temperature, 12 carbon dioxide adsorption, 13 solar cell, 14 energy savings, 15 micro/nano‐manufacturing technology, 16 flame retardants, 17 injection molding, 18 coating, 16,19 biomedicine, 20,21 flexible electronics, 21 aerospace, 22 automotive, 22 and defense industries 22 and so forth, due to their lightweight, low cost, low density, easy processing and flexible. However, it is common fact for polymer materials that those composites are extremely easy to be damaged due to the internal or external factors of polymer materials in the process of actual working 23‐27 .…”

Smart Textiles for Visible and IR Camouflage Application: State-of-the-Art and Microfabrication Path Forward

“…Solid–solid PCMs with a reversible change between amorphous, semi-crystalline and crystalline phases have also been developed [ 47 ]. Solid–solid PCMs have the advantage of small volume changes and are leakage-free during phase changes [ 47 , 48 ], thus avoiding the need for microencapsulation [ 20 ].…”

Ti3C2Tx MXenes reinforced PAA/CS hydrogels with self‐healing function as flexible supercapacitor electrodes

“…3D network hydrogels have received considerable attention in flexible supercapacitor research as marvelous conductive hydrogels with large specific surface area, well‐defined porous structure, giant strength and swift mass, and charge transport kinetics. These befitting merits also make it a potential substitute for the construction of flexible supercapacitor electrodes 17,18 . However, the low electrical conductivity and impoverished mechanical strength of ECHs limit its practical application in flexible electronic equipment 19 .…”
