| 摘 要： | 为开发具有良好抗菌性能的真丝内衣面料,采用原子转移自由基聚合法(ATRP),以真丝大分子制备引发剂,以CuBr/N,N,N′,N′′,N′′-五甲基二乙烯三胺(PMDETA)为催化体系,以水/乙醇为介质,将单体异丁酰酸-2-二乙氨基乙酯(DEAEMA)接枝到真丝织物上。X-线光电子能谱(XPS)检测Br以共价键方式固定到了真丝织物的表面,显示真丝大分子引发剂制备成功;衰减全反射红外光谱(ATR-FTIR)和差热扫描分析(DSC)均表明DEAEMA单体已接枝到真丝织物上,且织物的热稳定性能提高,热焓随接枝率的升高而降低;X-射线衍射图谱表明接枝反应主要发生在蚕丝纤维的无定形区,而结晶结构基本未改变。接枝后的真丝织物经季铵化处理后具有很好的抗菌性能,且抑菌率随接枝率增加而提高。

| Abstract: | In order to develop silk underwear fabric with good anti-bacterial property,the modified silk was prepared using 2-diethylaminoethyl methacrylate (DEAEMA) as monomer, CuBr/N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA) as catalyst system via atom transfer radical polymerization (ATRP) method in water/ethanol media. The result of X-ray photoelectron spectrum (XPS) showed that Br had been covalently bonded to the surface of silk fabric and silk macroinitiator was thus successfully prepared. The attenuated total reflectance-Fourier transfer infrared spectrum (ATR-FTIR) and differential scanning calorimetry (DSC) indicated that DEAEMA monomer had already been grafted on silk. The grafted silk had better thermostability and its enthalpy declined as grafting rate increased. X-ray diffraction curves showed that grafting mainly occurred at the amorphous region of silk fiber and structure of the crystal almost remained the same. The grafted silk had superior anti-bacterial property after quaternization. And the anti-bacterial rate increased with the grafting rate. |
