摘要：

为赋予聚乳酸(PLA)纤维高效的抗菌性能,采用熔融共混纺丝法分别制备了不同质量配比的二氧化钛接枝银纳米介孔微球(TiO2-Ag)/PLA纳米复合纤维和一定组成的TiO2/PLA纳米复合纤维,并对2种纤维的结构、热性能和抗菌性能等进行表征和分析。结果表明:当TiO2-Ag和TiO2这2种纳米粒子添加质量分数不超过3%时,可在PLA基体中较均匀地分散;2种粒子的加入均不影响PLA的玻璃化转变温度和结晶结构,但会使其熔融温度和热稳定性下降,加入质量分数为3%的TiO2后,导致PLA的结晶温度略有下降;随着TiO2-Ag质量分数的增加, TiO2-Ag/PLA纳米复合纤维对金黄色葡萄球菌和大肠杆菌的抑菌率不断增加;添加相同量的2种纳米粒子时,TiO2-Ag/PLA复合纤维对2个菌种的抑制效果明显优于TiO2/PLA复合纤维。

Abstract:

In order to endow the efficient antibacterial properties for poly(lactic acid) (PLA) fiber, the various mass ratios of TiO2-Ag/PLA nano-composite fibers were prepared by melt spinning. Moreover, TiO2/PLA nano-composite fiber with the certain mass ratio was also prepared under the same conditions. The structure, thermal properties and antibacterial properties of the two kinds of the nano-composite fibers were investigated and contrasted. The results show that two kinds of nano-particles can uniformly dispersed in PLA matrix when the contents of the nanoparticles are no more than 3%. The addition of two nano-particles have almost no influence on the glass transition temperature and crystalline structure of PLA, whereas their cooperation in PLA matrix decreases the melting temperature and thermal stability of PLA. Furthermore, when TiO2 nano-particles with the mass content of 3% are added, the crystalline temperature of PLA slightly reduces. The antibacterial ratio against Staphylococcus aureus and Escherichia coil of TiO2-Ag/PLA nano-composite fibers enhances with the increasing in the content of TiO2-Ag. When two kinds of nano-particles with the same mass ratio are added, TiO2-Ag/PLA nano-composite fiber has the higher antibacterial ratio against the two bacteria compared with TiO2/PLA nano-composite fiber.

Key words: poly(lactic acid), TiO2-Ag nano-mesoporous microsphere particle, nano-composite fiber, antibacterial property
