This review focuses on gelatin-based hemostatic hydrogels, which exert hemostatic effects through multiple mechanisms: physical hemostasis, physiological hemostasis, and synergistic hemostasis. These mechanisms enhance hemostatic efficacy for cutaneous wounds via distinct pathways. The hydrogels are further categorized according to different cross-linking strategies, with a systematic review and synthesis of their hemostatic mechanisms, properties, and applications. In vitro studies demonstrate their remarkable hemostatic performance across a spectrum of bleeding models. However, inherent limitations-such as suboptimal mechanical strength and reliance on single hemostatic pathways-necessitate addressing through material modification and composite cross-linking strategies. Emerging opportunities in anti-cancer drug delivery, food science, bone regeneration, and tissue engineering are also discussed.

Competition between elastically effective cross-linkers and dangling side chains creates a unique environment where reaction kinetics and steric effects dictate network percolation. The evolving viscoelasticity of linear and bottlebrush networks with an equivalent number of cross-linkers to backbones is measured during a catalytic curing reaction using time-resolved rheology. The impact of reaction kinetics on network formation is addressed through the sol-gel transition by tuning catalyst concentration. Solidification falls into a rate-limited regime where the modulus growth rate increases with increasing catalyst. The network formation process remains independent of the cure rate in the bottlebrush and linear systems. Side chains significantly decrease the fractal dimension of the critical gel cluster despite a comparable number of cross-links. Time-cure superposition is applied to quantify dynamics in the pre- and post-gel states. The divergence of the shift factors around the gel point is independent of cure kinetics. The collapse of shift factors in the post-gel region further suggests the universality of the network formation process.

In this study, a novel microcapsule (PU1) design is introduced that incorporates dynamic disulfide bonds, endowing the microcapsule walls with self-healing properties. Additionally, a comparative analysis is performed with conventional microcapsules (PU2) synthesized using 1, 4-butanediol. The prepared PU1 microcapsules exhibited a typical shell-core structure, and the median particle size decreased with increasing stirring speed. The glass transition temperature (T_g) of the prepared PU1 microcapsule is -53.2 °C, while that of the PU2 microcapsules is -45.0 °C. Moreover, after being placed at 60 °C for 24 h, the damaged PU1 microcapsules effectively self-healed. In contrast, the PU2 microcapsules do not demonstrate significant self-healing properties. Furthermore, elastomer films with the same chemical composition are prepared, and the tensile strength and the elongation at break of the PU1 elastomer are 7.3 MPa and 1450%, respectively, demonstrating excellent mechanical properties.

This study investigates the functionalization of triethylene glycol dimethacrylate (TEGDMA) with (3-aminopropyl)triethoxysilane (APTES) via a Michael addition reaction. The primary objective is to monitor functionalization progress and quantify monomer conversion under varying conditions. The focus is on dental composite applications, where controlled functionalization is crucial for optimal polymerization. Additionally, the study aimed to establish a broader range of reaction conditions to achieve variable monomer conversion, beneficial for diverse applications. The study explored various silane-to-monomer ratios (1:4, 1:2, 1:1, 2:1) and reaction times (2 h to 7 days) to determine optimal conversion conditions. Two analytical techniques, NMR spectroscopy and size exclusion chromatography (SEC), are used to assess functionalization and conversion. While NMR provided structural confirmation and quantification, SEC proved efficient for both qualitative and quantitative monitoring. It differentiated between single and double functionalization and accurately estimated conversion degrees, and provided accurate conversion estimates, with conversion rates reaching up to 60%. The results demonstrate that SEC is highly effective for tracking the functionalization process, offering reliable data on conversion and reaction kinetics. These findings confirm that controlling silane-to-monomer ratios and reaction time allows precise tuning of functionalization degree, which is critical for optimizing polymer properties. These findings are essential for tailoring monomer functionalization for applications beyond dental composites. The results demonstrate that SEC offers a sensitive and rapid method to monitor functionalization kinetics, complementing traditional NMR analysis. This dual-analytical approach represents a novel strategy for precisely tailoring monomer functionalization, which can significantly reduce polymerization shrinkage in dental composites and has potential applicability in other polymer systems requiring controlled functionalization.</p>","PeriodicalId":205,"journal":{"name":"Macromolecular Rapid Communications","volume":" ","pages":"e2500217"},"PeriodicalIF":4.2,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144232787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
