The influence of PBT content on the structural evolution and properties of the blend system was systematically investigated. These results indicate that the PBT content significantly influences the extent of transesterification and compatibility, thereby dictating the mechanical behavior of the monofilaments. At a low PBT content of 2 wt%, transesterification was negligible. The monofilaments exhibited a uniform radial gradient orientation without a distinct skin-core structure, demonstrating optimal overall mechanical performance with markedly improved strength. Specifically, the tensile, loop, and knot strengths were 611, 421, and 443 MPa, respectively. When the PBT content exceeded 5 wt%, the flexible chain segments of PBT enhanced the molecular chain mobility in the blend chips, leading to an increase in crystallite size. However, intensified transesterification concurrently reduces the crystallizability and degrades the mechanical properties. At PBT contents above 15 wt%, SEM analysis revealed phase separation and pronounced heterogeneity in the radial gradient structure of the blend monofilaments, resulting in a significant deterioration of the mechanical properties. This study elucidates the pivotal role of blending ratio in governing the “composition-structure-property” relationship of PET/PBT-blended monofilaments, revealing the underlying mechanism of transesterification and gradient structure development. These findings provide a theoretical foundation for the design of high-performance PET monofilaments.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 8","pages":"2775 - 2786"},"PeriodicalIF":4.6,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ethylene–vinyl acetate (EVA) foams are lightweight, flexible, and highly flammable, which restricts their broader engineering applications. In this study, a multifunctional additive, silane-modified zinc ion–reinforced melamine phosphate (ZnMP), was developed <i>via in situ</i> ion complexation and surface grafting to overcome the incompatibility between flame retardancy and mechanical performance in conventional intumescent systems. Compared to pristine melamine phosphate (MPP), ZnMP forms a coordinated structure through Zn<sup>2+</sup> interactions with nitrogen- and phosphorus-containing groups. When incorporated into the EVA foams at 15 wt%, ZnMP acted as an efficient heterogeneous nucleating agent, generating a dense microporous structure. Meanwhile, the silane coupling agent enhanced the interfacial interaction between the ZnMP and the EVA matrix, enabling effective reinforcement. Consequently, the EVA/ZnMP foam exhibited significantly improved mechanical properties, including a 144.3% increase in storage modulus, 21.4% increase in energy adsorption, and 88.6% cyclic compression retention after 10 cycles (80% strain). In addition, Zn<sup>2+</sup> promoted the formation of a compact char layer during combustion, leading to excellent flame-retardant performance with a limiting oxygen index (LOI) of 25.3%, UL-94 V-0 rating, and a 41.0% reduction in the peak heat release rate. This ion-coordination and interfacial modification strategy offers a promising route for developing lightweight EVA foams with balanced mechanical reinforcements and flame-retardant properties for cushioning and protective applications.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 8","pages":"2758 - 2774"},"PeriodicalIF":4.6,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent innovations in nickel-based catalysts have radically altered olefin polymerization, facilitating precise regulation of the polymer microstructure and integration of polar monomers. This review addresses the recent developments in <i>α</i>-diimine nickel catalysts, SHOP-type systems, and iminopyridyl-based complexes, focusing on the impact of steric and electronic ligand alterations on thermal robustness, catalytic activity, and molecular weight control. To clarify its function in adjusting the mechanical and thermal characteristics, the chain-walking mechanism, which is essential for creating branched architectures, was broken down. Breakthroughs, including supramolecular shielding and fluorine effects, in addition to dinuclear architectures, have led to ultrahigh-molecular-weight polyethylenes (UHMWPEs), semicrystalline materials, and thermoplastic elastomers directly from ethylene. In addition, the resulting approaches for copolymerizing ethylene with polar monomers (acrylates, norbornene) or carbon monoxide have revealed routes to functionalized and photodegradable polyolefins. Despite these outcomes, challenges remain in accomplishing highly polar comonomer incorporation and commercial scalability. This review highlights nickel catalysts as an adaptable framework for sustainable polyolefin innovation, connecting academic research with applications in packaging, biomedicine, and recyclable materials.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 8","pages":"2453 - 2483"},"PeriodicalIF":4.6,"publicationDate":"2026-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In good solvents, increasing the particle concentration induces deswelling because of the enhanced crowding-induced osmotic compression. Increasing the molecular mass of the solvent could also enhance deswelling by suppressing solvent penetration into the nanoparticle network. Equilibrium relations derived from the osmotic-pressure balance are developed to describe these two mechanisms and are shown to capture the simulation results. A single unified framework can describe the deswelling over a broad range of solvent masses and particle concentrations. In addition, varying the solvent mass shifts the fragility transition observed experimentally in solutions of soft nanoparticles, thereby linking deswelling to changes in the glassy dynamics.

To overcome this limitation, we introduced an ultra-low loading of 5,10,15,20-tetra(4-aminophenyl) porphyrin (TAPP) as a multifunctional crosslinker into a polyimide (PI) matrix. TAPP simultaneously establishes covalent crosslinking and trap engineering, and its amino groups form a robust network with PI chains, whereas the porphyrin cycle acts as an efficient deep-level charge trap, effectively suppressing CTC formation and charge migration. The optimized PCPI films exhibited a tunable nonmonotonic dielectric constant while maintaining a low loss. The PCPI-0.1 sample shows a significantly enhanced breakdown strength and achieves high discharge energy densities of 8.78, 6.09, and 4.97 J·cm<sup>−3</sup> at 25, 150, 200 °C, respectively, while maintaining an efficiency above 85%. Remarkably, PCPI-0.1 delivered superior energy density compared to most high-temperature polymer dielectrics reported in the literature, coupled with excellent cycling stability and aging resistance.
