【摘要】：以6-O-乙烯基己二酸-D-吡喃型半乳糖(OVNGA)和溫敏性的二聚乙二醇單甲醚甲基丙烯酸甲酯(DEGMA)作為單體,采用酶促法、可逆加成-斷裂鏈轉(zhuǎn)移自由聚合法(RAFT)和"一鍋法"聯(lián)用,并與金納米粒子(AuNPs)復(fù)合,制備了具有溫敏性的含半乳糖基的PDEGMA-b-POVNGA@AuNPs復(fù)合物。通過1HNMR、FTIR和GPC對PDEGMA-b-POVNGA進(jìn)行了結(jié)構(gòu)表征,UV-Vis、TEM和DLS對AuNPs和PDEGMA-b-POVNGA@AuNPs進(jìn)行了性能測試,變溫UV-Vis對PDEGMA-b-POVNGA及PDEGMA-b-POVNGA@AuNPs復(fù)合物進(jìn)行了溫敏性考察。結(jié)果表明:PDEGMA-b-POVNGA@AuNPs復(fù)合物是由PDEGMA-b-POVNGA和AuNPs以S—Au鍵鍵合,將聚合物接枝到了AuNPs表面。PDEGMA-b-POVNGA的Mn和Mw分別為9.42×104和1.45×105。AuNPs平均粒徑為25 nm。PDEGMA-b-POVNGA和PDEGMA-b-POVNGA@AuNPs的低臨界溫度(LCST)分別約為35.0和34.5℃。
[Abstract]:The temperature sensitivity of PDEGMA - b - POVNGA and PDEGMA - b - POVNGA and PDEGMA - b - POVNGA - POVNGA and PDEGMA - b - POVNGA - POVNGA - POVNGA - POVNGA and PDEGMA - b - POVNGA - POVNGA - POVNGA - POVNGA and PDEGMA - b - POVNGA - POVNGA were investigated . The results showed that the PDEGMA - b - POVNGA - POVNGA and PDEGMA - b - POVNGA - POVNGA @ AuC were prepared by means of 1H NMR , FTIR and GPC . The results showed that the low critical temperature ( LCST ) of PDEGMA - b - POVNGA and PDEGMA - b - POVNGA and PDEGMA - b - POVNGA @ Aurea was about 35.0 and 34.5 鈩，
