Constructing mechanically robust, efficient self‐healing, high‐energy, and recyclable energetic composites by hybrid dynamic lock strategy

SmartMat, Год журнала: 2024, Номер 5(5)

Опубликована: Янв. 31, 2024

Abstract It is still a huge challenge to introduce effective crack‐healing ability into energetic composites with high oxidizer content. In this article, poly(urea‐urethane) elastomer was prepared by the polycondensation reaction of glycidyl azido polymer (GAP), isophorone diisocyanate (IPDI), and 2‐aminophenyl disulfide (2‐APD). structure, hybrid dynamic lock, including multilevel H‐bonds bonds, not only provides abundant interactions promotes chain diffusion, but also enhances physical crosslinking density. Such unique design fabricated robust tensile strength (0.72 MPa), stretchability (1631%), outstanding toughness (8.95 MJ/m 3 ) in field polymers. Meanwhile, exhibited self‐healing efficiency (98.4% at 60 °C) heat release ( Q = 1750.46 J/g). Experimental theoretical results adequately explain mechanism, particularly role units. The high‐solid content (80 wt%) based on presented micro‐defect (97.8%) recycling without loss mechanical performance. development smart excellent recyclable meaningful way for wide range applications materials.

Photo-Cross-Linkable Hydrogel with Lubricating, Antimicrobial, and Antioxidant Properties for Bacteria-Infected Wound Healing

Chemistry of Materials, Год журнала: 2024, Номер 36(12), С. 6114 - 6129

Опубликована: Июнь 3, 2024

Wound healing is a prolonged physiological process involving series of complicated biological responses influenced by various factors, such as bacterial infection and oxidative damage. Existing treatments, while effective, have certain limitations in terms biocompatibility, responsiveness to the wound environment, efficacy promoting tissue regeneration. To address these shortcomings, bioinspired hydration lubrication mechanism articular cartilage, we successfully designed developed an injectable situ photo-cross-linkable hydrogel, which was synthesized via modifying aminated hyaluronic acid with polymer obtained free radical polymerization o-nitrobenzyl alcohol derivative (NB) 2-methoxyethyl phosphocholine (MPC). The hydrophilic layer formed around zwitterionic charges MPC endowed hydrogel enhanced antimicrobial effects, whereas hydroxymethyl group NB enabled ultraviolet light-induced cross-linking property. doped polydopamine nanoparticles, facilitated multifaceted photothermally responsive antibacterial, anti-inflammation, angiogenesis. Specifically, upon injection precursor solution into site exposure light, cross-linked adhered closely skin tissues, achieving hemostasis exudate absorption. Additionally, showed excellent reactive oxygen species scavenging property, reducing cellular stress meanwhile bactericidal effect near-infrared light irradiation. Furthermore, its networked porous structure, conducive cell adhesion proliferation, remarkably enhancing activity wound-healing performances were investigated both vitro vivo experiments, showcasing potential for treatment applications, offering promising improvement over current methods providing photothermal responsive, biocompatible, effective process.

Polydopamine (PDA), inspired by the adhesive mussel foot proteins, is widely applied in chemical, biological, medical, and material science due to its unique surface coating capability abundant active sites. Energetic materials (EMs) play an essential role both military civilian fields as a chemical energy source. Recently, PDA was introduced into EMs for modification of crystal phase stability interfacial bonding effect, and, result, enhance mechanical, thermal, safety performances. This mini-review summarizes representative works modified from three perspectives. Before that, self-polymerization mechanisms dopamine methods accelerating this process are briefly presented consideration researchers field. The future directions remaining issues field also discussed at last mini-review.
