With the development of electronic equipment and advancement environmental camouflage technology, higher requirements are placed on flexibility, thermal conductivity, heat storage capacity phase change films. This work fabricated a high-performance dual-encapsulation composite film through employment Pickering emulsion polymerization sol-gel techniques, incorporating n-octadecane (n-OD), liquid metal gallium (Ga), poly(p-phenylene benzobisoxazole) (PBO). Phase microcapsules (PM) serve to prevent leakage during changes, maintain high levels enthalpy, enhance dispersion n-OD in matrices, as well improve adhesion at interfaces. It is possible achieve excellent conductivity with only small amount modified Ga (MGa) by chitosan quaternary ammonium salt confined network since material has smaller size more uniform distribution. Owing its distinctive structural design modification strategy, (MGa/PM/PBO) manifests outstanding mechanical properties (featuring tensile strength 7.0 MPa), remarkable (9.4752 W m-1 K-1) in-plane), (100.9 J g-1). harbors significant potential for application management devices camouflage.

Abstract Solid–solid phase change materials (SSPCMs) have received great interest due to their exceptional thermal management and superior shape stability. However, traditional crosslinked structures predominantly rely on ester groups, which limits applicability under extreme conditions such as high humidity. Herein, a novel strategy is presented for preparing SSPCMs with excellent latent heat environmental robustness via thiolactone ring‐opening reactions. Easily synthesized copolymers provide abundant reactive sites are then functionalized alkyl amines acrylates grafted components. A small amount of polyetheramine employed crosslink the copolymer, forming robust network. The resulting exhibit tunable transition temperatures (44.7–61.0 °C) enthalpies (20.3–98.9 J g −1 ). Owing density can maintain stability mechanical properties, when immersed in water, acid, alkaline 2 h. In addition, films demonstrate reversible information encryption, memory infrared stealth properties. When integrated polydopamine nanoparticles, these also solar‐thermal stores/releases capacity. Collectively, unique features new insights ideas development next generation smart materials.
