Polyzwitterion (PZW) hydrogel has excellent marine anti-biofouling performance, but it is difficult to effectively work for a long time in natural seawater due its weak mechanical strength. In this study, new rubber (NR)-PZW composite been reported long-term by simply dispersing NR latex into the poly(sulfobetaine methacrylate) (PSBMA) network. First of all, owing PZW network having an anti-polyelectrolyte effect, NR-PZW can provide outstanding including broad-spectrum anti-bacteria, anti-algae, and anti-protein properties environments. Furthermore, composited nanoparticle with hydrophilic negatively charged outer protein membrane, which uniformly disperse significantly improve properties. Therefore, not only highly enhanced tensile strength (0.52 MPa) also ultra-high breaking elongation (738%), effectually resist harsh As result, achieve performance more than 3 months within real environment. This excellent, robust polyzwitterionic anti-biofouling, will inspire strategies materials.
