Smooth, durable, ultrathin antifouling layers are deposited onto commercial reverse osmosis membranes without damaging them and they exhibit a fouling reduction. A new synergistic approach to antifouling, by coupling surface modification and drinking-water-level chlorination is enabled by the films' unique resistance against chlorine degradation. This approach substantially enhances longer-term fouling resistance compared with surface modification or chlorination alone, and can reduce freshwater production cost and its collateral toxicity to marine biota.
光滑、耐用、超薄的防污层被沉积在商用反渗透膜上,且不会对其造成损害,这些防污层具有减少污垢的作用。通过将表面改性与饮用水级氯化相结合的一种新型协同防污方法,因这些薄膜对氯降解具有独特的抗性而得以实现。与单独的表面改性或氯化相比,这种方法显著增强了长期抗污能力,并且可以降低淡水生产成本及其对海洋生物群的附带毒性。
