The authors of this work propose the construction reversibly interlocked macromolecular networks (RILNs) at interface between immiscible polymers to address common challenge arising from compounding different together. proof-of-concept model system is made by stacking cross-linked polyether and styrene–butadiene block copolymer, which, respectively, contain reversible Schiff base Diels–Alder (DA) bonds. By taking advantage synergy topological rearrangement dynamic migration pre-embedded zinc ion catalyst, interdiffusion interlocking temporarily de-cross-linked chains can be purposely synchronized. Consequently, envisaged interfacial RILNs with decent mechanical properties are successfully prepared in solid state, which an advancement over traditional that have assistance solvent. resulting binding tight because massive chain entanglements region degradability as well. It anticipated methodology discussed paper would hopefully developed into a facile technique for fabrication high-performance polymer blends regardless miscibility raw materials.

The practical application of energetic materials, particularly 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20), is frequently impeded by phase transition challenges. In this study, we propose a novel strategy to enhance the stability CL-20 employing thermo-sensitive polymer, poly(N-isopropylacrylamide) (PNIPAM), modulate its transitions. Our approach involves use an in-situ polymerized polydopamine (PDA) shell as platform for surface grafting through atom transfer radical polymerization, yielding core-shell structured CL-20@PDA-PNIPAM. Through comprehensive characterization, successful PNIPAM confirmed, significantly enhanced CL-20. Notably, our structure exhibits 13 °C increase in temperature compared raw CL-20, thereby delaying ε→α over 80 min under combined thermal and solvent conditions. attributed hydrophobic nature above low critical solution water, which effectively shields crystal. These findings provide new insights into enhancing safety materials complex environments, highlighting potential molecular switch mechanism.
