| 摘 要： | 通过三元共聚将马来酸酐活性基团引入大分子链中,制备了两个系列的反应性高分子抗菌剂poly(DMAEMA-BC/AAm/MAn)和poly(DMAEMA-DB/AAm/MAn),并用FT-IR对合成的反应性高分子抗菌剂进行了结构表征,用酸碱滴定法测定了其酸值,通过平板活菌计数法测定了反应性高分子抗菌剂的抗菌活性,并表征了它们的抗菌活性对抗菌时间与浓度的依赖关系。通过热整理工艺将三元共聚物与棉织物反应,制得抗菌织物。之后,通过改良振荡烧瓶法测定了抗菌整理后棉织物的抗菌效果,并进一步考察了织物抗菌效果的耐洗性。研究结果表明,少量的马来酸酐(单体摩尔比5%)有助于提高共聚单体的反应活性,共聚物中含少量马来酸酐时,抗菌活性增强。用马来酸酐单体摩尔比5～35%的poly(DMAEMA-BC/AAm/MAn)或5～25%的poly(DMAEMA-DB/AAm/MAn)整理的抗菌织物均具有良好的抗菌效果,且前者经过100次水洗,后者经200次水洗后,仍表现良好的抗菌效果。

| Abstract: | Two series of reactive polymeric antibacterial reagents,poly(DMAEMA-BC/AAm/MAn) and poly(DMAEMA-DB/AAm/MAn),were synthesized by a three-block copolymerization including maleic anhydride monomer.The structures and acid values of these antibacterial copolymers were determined by FT-IR and NaOH titration,respectively.The antibacterial activities and their dependence on contact time and dosage of the copolymers were investigated by a viable cell counting method.Through a thermo-treatment process,the three-block... |
