Abstract Phase change materials (PCMs) have drawn considerable attention in recent years due to their capability of storing and releasing thermal energy during phase transformation. However, traditional PCMs face challenges like limited conductivity, leakage while transformation from solid liquid, degradation, durability. Researchers concentrated on creating shape‐stabilized (SSPCMs) employing polymers as the supporting matrix overcome these difficulties incorporating highly thermally conductive additives improve conductivity. Compared conventional PCMs, polymer‐based SSPCMs are often more flexible, lightweight, durable may be easily customized according specific applications. Various factors PCM loading, cyclability, cost‐effectiveness environmental concerns must considered constructing SSPCMs. This review paper comprehensively explored various polymers, including polyurethane, polyacrylates, polyolefin, so on, promising for relatively high mechanical strength, compatibility with PCM, excellent stability, chemical resistance. Natural chitosan, cellulose, starch also eco‐friendly solutions. We discussed about properties each polymer, cost‐effectiveness, impact developing such guide researchers material selection. Applications solar storage, medical devices, building materials, electronics, transportation industry, waste heat recovery briefly discussed. Finally, some future development areas been attract new this field. The information provided will assist readers understanding SSPCM selecting desired polymer support diverse application methods.

A promising approach to prevent heat- and cold-related illnesses is the integration of zero-energy input control technology into personal thermal management (PTM) systems while reducing energy consumption. However, achieving optimal wearing comfort maintaining subambient metabolic temperatures using thermally regulating materials without an supply remains challenging. In this study, we provide a simple reliable methodology produce phase-changeable metafabric made thermoplastic polyurethane phase change capsule (PCC) particles with high moisture permeability comfort. This skillfully incorporates spray-formed PCC three-dimensional nanofibrous aggregate, forming stable self-entangled network structure in single step through simultaneous humidity-assisted electrospraying electrospinning processes. Additionally, demonstrates prominent water resistance superhydrophobicity, which are attributed nanofibers, resulting formation microporous/nanoporous resembling surface lotus leaf. As result, shows active passive performance, vapor transmittance rate 13.1 kg m
