Statistical copolymers have been extensively used in chemical industries and our daily lives, owing to their ease of synthesis functionalization. However, self-assembly based on statistical has haunted by high interfacial energy, poor stability, low concentration. We proposed the copolymerization-induced (

The integration of supramolecular chemistry with polymerization-induced self-assembly (PISA) offers a promising avenue to advance the design and functionality nanomaterials. Here, we elucidate role sulfone bonding in aqueous block copolymer (BCP) by evaluating PISA behaviors sulfone-functionalized BCPs stimuli-responsive properties resulting assemblies. A series 2-(alkylsulfonyl)ethyl acrylamides were designed for PISA, which moiety not only enhances monomer water solubility but also stabilizes polymer assemblies through bonding. Systematic variation alkyl tail revealed distinct behaviors, where shorter tails favored sulfone-bond-dominated assembly, while longer introduced competitive hydrophobic interactions. This interplay between hydrophobicity enabled fabrication programmable ion-responsive morphology transitions. Our findings provide fundamental insights into interactions establish versatile strategy engineering adaptive

Polymerization-induced microphase separation strategy offers an effective approach for designing hydrogels with microphase-separated structure. In this study, a kind of was fabricated by copolymerizing histidine methacrylamide and methacrylic acid monomers. Spontaneous occurred during the polymerization process, which driven strong hydrogen bonding interactions between imidazole carboxyl groups, stabilizing hydrophobic methyl groups. The exhibited significantly enhanced mechanical properties, achieving stiffness 67 MPa, tensile strength 2.2 toughness 8.3 MJ/m3, fracture energy 7.0 kJ/m2, superior dissipation capabilities. These also remarkable antiswelling performance across broad pH range (pH 3-11). Notably, remained in glassy state at room temperature. Moreover, displayed excellent cytocompatibility. This study provides valuable insights into design hydrogels, paving way their practical applications biomedical engineering.

Mammals can rapidly form shear-resistant blood clots to plug vascular damage by gluing cells together. Inspired the mechanism of clotting, we proposed use polymerization-induced multivalent interactions as a general strategy for preparing colloidal hydrogels comprising strongly bonded soft micellar particles with high stretchability and toughness. Specifically, poly(methacrylic acid)-b-poly(isobornyl acrylate) spherical micelles were prepared mixed acrylamide, which formed monovalent hydrogen bonds corona micelles. The in situ polymerization acrylamide yielded polyacrylamide (PAM), physically cross-linking micelle hydrogel. formation hydrogel was confirmed attenuated total reflectance Fourier-transform infrared spectroscopy. mechanical properties tunable varying concentration hydrogen-bonding monomer, micelles, nanostructure universality this demonstrated designing various using different types monomers. be potential flexible strain sensor owing its This study provides new insights into design based on particles.
