“…20 Similarly, Liu et al added SiO 2 into polyacrylonitrile nanofibrous membranes, enhancing membrane durability. 21 Considering the cost-effectiveness and performance-enhancing advantages of SiO 2 , we chose it as the main filler to improve the mechanical properties of the PEG hydrogel. Employing the in situ polymerization method to synthesize SiO 2 isocyanate, we achieved good interface compatibility, thereby enhancing the bonding strength of the SiO 2 /PEG hydrogel.…”

Until now, traditional hydrogels have no long-term application in ship antifouling owing to their poor mechanical properties. Herein, the synergetic application strategy of nitrogen-doped carbon dots loaded silica (SiO 2 @N-CDs) nanoparticles to enhance polyethylene glycol (PEG) hydrogel membrane was proposed. The incorporation of SiO 2 @N-CDs improves the water retention and mechanical properties of the hydrogel. Importantly, the SiO 2 @N-CDs/PEG hydrogel exhibits remarkable antiadhesion capacity against bacteria, showing excellent antifouling performance. Fluorescence distribution analysis indicates alterations in the surface and fracture morphology of the hydrogel owing to SiO 2 @ N-CDs, with a "twill-fold" change in fracture. In addition, molecular dynamics simulations show that SiO 2 enhances the hydration layer of the hydrogel, contributing to its enhanced water retention effect. These findings provide avenues for the development of ship antifouling materials.
