摘要:
 以2-溴异丁酰溴修饰过的真丝织物为大分子引发剂,CuBr/PMDETA为催化体系,在水介质体系中采用原子转移自由基聚合(ATRP)法,将甲基丙烯酸羟乙酯(HEMA)接枝在真丝织物表面。研究了单体及催化剂浓度、pH值、反应时间对实验影响,通过ATRFTIR、X-射线衍射和SEM等表征了接枝真丝织物的结构,并测试了其各项物理性能。结果表明,通过ATRP法成功将HEMA接枝到真丝表面,接枝反应主要发生在丝素的无定形区,接枝聚合物在真丝表面分布均匀,且接枝后织物抗皱性有较大提高。
Abstract:
Hydroxyethyl methacrylate (HEMA) was grafted onto silk surface using 2-bromoisobutyryl bromide (BriB-Br) modified silk as macroinitiator, and CuBr/N,N,N’,N",N"-pentamethyldiethylenetriamine (PMDETA) as catalyst system, in aqueous medium via atom transfer radical polymerization (ATRP) method. The effects of monomer concentration, catalyst concentration, pH value and reaction time on silk grafting were studied. The grafted silk was characterized by ATR-FTIR, X-ray diffraction and scanning electron microscope (SEM), and its physical properties were tested. The results showed that HEMA was successfully grafted onto silk surface via ATRP method; the grafting primarily happened at the amorphous region of silk fibroin and the grafted polymers uniformly distributed on the silk surface. The crease resistance of the grafted silk fabric was remarkably improved.
