Abstract

Abstract:

This paper reviews recent advances in composite phase change materials （PCMs） based on the thermoplastic elastomer styrene⁃ethylene⁃butylene⁃styrene （SEBS）. It systematically covers the structural design of SEBS⁃based PCMs and their resulting thermal， dielectric， and flexible properties. Furthermore， the paper outlines the application progress of SEBS⁃based PCMs in various fields， including thermal management of electronic components， building energy efficiency， and personal thermal management. Finally， the review provides a perspective on the future industrialization of high⁃performance， high⁃value⁃added SEBS⁃based PCMs.

Key words: thermoplastic elastomer, butadiene?butadiene?styrene block copolymer, composite phase change material, flexibility, heat storage property
