There is an emerging requirement of advanced functional materials for simultaneous thermal protection and electromagnetic wave‐transparent transmission applications. A novel polyimide (PI) aerogel‐based sandwich‐structural composite is developed to meet such a requirement in this study. This composite is based on a unidirectional fluorinated PI (FPI) aerogel as a lower layer, a nondirectional conventional PI aerogel as a middle layer, and a nondirectional FPI aerogel/paraffin phase‐change composite as an upper layer. The lower layer exhibits a unique unidirectional porous microstructure and an ultralow dielectric constant of 1.04. The upper layer possesses a dynamical temperature regulation capability thanks to its loaded paraffin having a high latent heat capacity of 242.7 J g−1. The presence of the nondirectional PI aerogel middle layer can effectively prevent against the leakage of paraffin from the upper layer to the surface of the composite. Through a rational integration of three functional layers, the developed sandwich‐structured composite not only can provide gradient thermal protection for hot objects over a long period but also exhibits an excellent wave‐transparent capability to establish communication between two electromagnetically shielded electronic devices. With such prominent thermal insulation and wave‐transparent functions, the sandwich‐structured composite exhibits great potential for specific applications in aircraft, spacecraft, radar systems, and satellite communication.

Battery thermal management system (BTMS) based on phase change materials (PCMs) is simple in structure while presenting outstanding performance, but the core bottleneck hindering the industrialization of which is the poor performance of PCMs’ pivotal properties. Apart from that, under extreme conditions, single passive phase change temperature‐control technology apparently could not meet the demands. Therefore, modification strategies to improve PCM's pivotal properties suitable for BTMS are thoroughly reviewed. Moreover, the optimization of as‐mentioned passive systems by integrating them with other active heating or cooling devices to obtain advanced active and passive full‐temperature responsive capability is also summarized. Profound opinions concerning about the prospect and challenges of PCM‐BTMS are given. It is expected to provide some innovative ideas for the advancement of such promising technology.
