“…[14][15][16][17] Hult et al 18 showed that hyperbranched and star-shaped acrylate polymers had the characteristics of lower viscosity, faster curing rate, higher hardness, lower shrinkage, and better chemical resistance after curing than traditional UV-curable resins under the same molecular weight. 19,20 Zhang et al 21 synthesized a group of hyperbranched poly (ethylenimine)-graft-poly (ethylene glycol) (bPEI-g-PEG) multi-arm star copolymers with different PEG grafting ratios. Then, the star-shaped PEG-based coating was prepared by fixing the corresponding copolymer on the substrate coated with poly dopamine (PDA).…”

UV‐curable coatings mainly include vinyl resin, active thinner, and photoinitiator, among which UV‐curable resin accounts for a large proportion and is the main factor that determines the film performance. Existing vinyl resins have the disadvantages of high viscosity, high cost, and low curable function. Herein, the polyol as the core, first reacted with anhydride to produce half ester, and then with glycolyl methacrylate ring opening to get vinyl star polyester. The molecular structure and molecular weight of UV‐curable star polyesters were analyzed using FTIR, 1H NMR, and GPC. The impact of the type and ratio of anhydride and small molecular polyols on the viscosity and coating properties of vinyl star polyester were investigated. The results indicated that the resin viscosity and film hardness increased as the hydroxyl function of small molecular polyols increased. It was also discovered that the inclusion of polyether polyol N210 in the reaction system reduced the viscosity of the resin to 2025 mPa s and improved the hardness of the film to 2H, as well as its impact toughness.

“…l -DOPA, being an in vivo instantly available catecholamine, oxidizes to polylevodopa (PDOPA). This reaction, proceeding under only the mechanical stirring regime, at the solid–liquid interface might form a controllable layer of excellent adhesiveness/affinity to numerous materials. − Such a biologically inspired functionalization, essential in the formation of mussels, could be “translated” into the surface modification of graphene with l -DOPA and the subsequent interface polymerization via the “grafting-from” mechanism. This route could be effective in preventing graphene from the excessive agglomeration in the polar solvents.…”

Water-based processing of graphene—typically considered as physicochemically incompatible with water in the macroscale—emerges as the key challenge among the central postulates of green nanotechnology. These problematic concerns are derived from the complex nature of graphene in the family of sp 2 -carbon nanoallotropes. Indeed, nanomaterials hidden under the common “graphene” signboard are very rich in morphological and physicochemical variants. In this work, inspired by the adhesion chemistry of mussel biomaterials, we have synthesized novel, water-processable graphene–polylevodopa (PDOPA) hybrids. Graphene and PDOPA were covalently amalgamated via the “growth-from” polymerization of l -DOPA ( l -3,4-dihydroxyphenylalanine) monomer in air, yielding homogeneously PDOPA-coated (23 wt %) (of thickness 10–20 nm) hydrophilic flakes. The hybrids formed >1 year stable and water-processable aqueous dispersions and further conveniently processable paints of viscosity 0.4 Pa·s at 20 s –1 and a low yield stress τ 0 up to 0.12 Pa, hence exhibiting long shelf-life stability and lacking sagging after application. Demonstrating their applicability, we have found them as surfactant-like nanoparticles stabilizing the larger, pristine graphene agglomerates in water in the optimized graphene/graphene–PDOPA weight ratio of 9:1. These characteristics enabled the manufacture of conveniently paintable coatings of low surface resistivity of 1.9 kΩ sq –1 (0.21 Ω·m) which, in turn, emerge as potentially applicable in textronics, radar-absorbing materials, or electromagnetic interference shielding.

Superamphiphilic TiO₂ Composite Surface for Protein Antifouling

Unwanted protein adsorption deteriorates fouling processes and reduces analytical device performance. Wettability plays an important role in protein adsorption by affecting interactions between proteins and surfaces. However, the principles of protein adsorption are not completely understood, and surface coatings that exhibit resistance to protein adsorption and long‐term stability still need to be developed. Here, a nanostructured superamphiphilic TiO2 composite (TiO2/SiO2) coating that can effectively prevent nonspecific protein adsorption on water/solid interfaces is reported. The confined water on the superamphiphilic surface enables a low adhesion force and the formation of an energy barrier that plays a key role in preventing protein adsorption. This adaptive design protects the capillary wall from fouling in a harsh environment during the bioanalysis of capillary electrophoresis and is further extended to applications in multifunctional microfluidics for liquid transportation. This facile approach is not only perfectly applied in channels with complicated configurations but may also offer significant insights into the design of advanced superwetting materials to control biomolecule adhesion in biomedical devices, microfluidics, and biological assays.
