Summary: A solid-state electrolyte film with high ionic conductivity, flexibility, and self-adhesive properties was developed based on a fluorinated, microphase-separated comb copolymer. The film showed excellent performance in solid supercapacitors, outperforming conventional electrolytes. This innovative electrolyte film eliminates the need for separators, adhesives, or packaging processes in supercapacitor fabrication.

Summary: This paper investigates the effects of HTPBs with different main-chain microstructures on their triblock copolymers and polyurethane properties. Three polyether-modified HTPB triblock copolymers were synthesized using three HTPBs with different microstructures prepared via different polymerization methods. The results showed that the triblock copolymers had lower viscosity and Tg values as the HTPB 1,2 structure content decreased, while the effect on the thermal decomposition temperature was not significant. The analysis of the polyurethane elastomers revealed that an increase in the content of the 1,2 structure in HTPB led to an increase in breaking strength and a decrease in elongation at break.

Summary: This study introduces a non-fluorinated volumetric superhydrophobic nanocomposite with excellent mechanochemical robustness. The water-repellency of the nanocomposites can be adjusted by changing the mass ratio of diatomaceous earth to fumed silica. Furthermore, the nanocomposite maintains high water contact angle and low contact angle hysteresis after undergoing various mechanical durability tests.

Summary: This paper investigates the self-assembly properties and aggregation behavior of amphiphilic water-dispersed polyester (WPET) with different sulfonate group contents. The effects of WPET concentration, temperature, and electrolytes on the aggregation behavior are systematically studied. The results show that high sulfonate group content leads to higher stability, while low sulfonate group content makes the dispersion sensitive to electrolytes. WPET concentration, temperature, and electrolytes play important roles in controlling the self-assembly and aggregation of WPET molecules.

Summary: Photocurable polymer with fast curable properties was utilized for 3D-printed propellants. The synthesis and characterization of photocurable fluorinated polyether-based reactive inks were outlined. Through esterification, acrylate-terminated poly-2-((2,2,3,3,3-pentafluoropropoxy)-methyl) ethylene oxide (P5F-AA) was obtained as a photocurable binder. UV radiation was used to prepare a new type of photocurable resin for additive manufacturing of energetic materials, which exhibited maximal mechanical strength and elongation at break due to the introduction of mono- and multifunctional diluents. The results from different techniques suggested that the photocurable reactive ink may serve as a reference and guiding importance for design of reactive inks for 3D-printed propellants.

Summary: The length of the corona in spherical micelles of block copolymers is determined by the molecular weight of the corona-forming block relative to that of the core block before assembly. By selectively extending the corona block using surface-initiated polymerization, it is possible to convert crew-cut micelles to hairy micelles while maintaining the spherical shape. This method allows for the creation of micelles with different corona lengths and shapes, providing insight into the packing problem in copolymer micelle assembly.

Summary: This study presents a method for preparing a polymer carrier for a boron delivery agent through a combination of experimental and computational studies. Micelles with (B12 + QP2VP)-core and PEO-corona were formed by the electrostatic association between QP2VP and B12. The micelles were then utilized as building blocks to construct layer-by-layer microparticles, which successfully delivered boron to cells. This research contributes to a fundamental understanding of self-assembled structures and provides a basis for further development of boron-containing polymer vehicles for boron neutron capture therapy.

Summary: A unique cyclic-hanging-multicyclic polymer topology was developed by a ring-opening metathesis polymerization (ROMP)-based grafting-through approach and ladderphane-mediated blocking-cyclization technique. The complex structure and chemical composition of the multicyclic polymer was characterized and confirmed. Importantly, the cyclic molecular topology could be directly visualized without the need for tedious post-modification processes.
