　　有機污染物造成的水污染是人類和環(huán)境生態(tài)系統(tǒng)的嚴重問題�；瘖y品、紡織、塑料、造紙、食品加工等多個工廠使用大量的染料。由于染料不可生物降解的性質,染料向水圈(河流、湖泊、海洋等)的排放給人類社會帶來了許多挑戰(zhàn)。此外,非常低濃度的染料(<1 mg/L)對水體生態(tài)的影響也是顯著的。同樣,醫(yī)院中與醫(yī)療保健相關的感染對醫(yī)療保健系統(tǒng)造成嚴重的經濟后果。大多數諾氏菌感染是由耐藥或耐多藥細菌產生的,如大腸桿菌、金黃色葡萄球菌和β溶血性鏈球菌。新型抗菌材料的設計是制定控制醫(yī)療相關感染新戰(zhàn)略的最重要挑戰(zhàn)之一。此外,還特別關注抗氧化活性高的天然物質。事實上,由多種因素弓起的氧化應激是許多病理狀況產生的主要原因,如炎癥、癌癥、冠心病甚至皮膚老化。為了克服所有這些問題,設計新材料已成為研究人員應對現實世界中迫切需要的一大挑戰(zhàn)。為了達到這一目標,人們非常重視開發(fā)新的路線,以設計和合成具有理想性能的材料。因此,研究者已作出努力,以最低的生產成本研制多種卓越的功能化新復合材料。本論文研究致力于研究構建新型高效、優(yōu)異穩(wěn)定性和可重復使用性的雜化復合材料,并開展多種應用研究。以下是本文研究的內容:1、本文報道了一種使用...
