摘要(Abstract)：

通过原位聚合法和共混法制备了系列不同含量氧化亚铜(Cu_2O)的PET/Cu_2O纳米复合树脂。采用红外光谱、扫描电子显微镜表征了Cu_2O的结构与尺寸,利用扫描电子显微镜、热重分析仪、差示扫描量热仪、X射线衍射仪、复丝强力仪等分别评价了纳米Cu_2O在复合纤维中的分散性以及复合纤维的热力学性能、结晶性能及力学性能。研究表明:相对于共混法复合纤维表面的纳米粒子团聚现象,原位聚合法制备的复合纤维的表面纳米Cu_2O分布均匀;原位聚合法制备的复合纤维的断裂强度比共混法提高了47%~72%。抗菌性测试发现:当纳米Cu_2O质量分数为0.2%时,复合纤维抗菌率可达到99.73%。
A series of PET/Cu_2O nano-composite resin with different contents of cuprous oxide were pre-pared by melt blending and in-situ polymerization method. The structure of composite resin, the dispersionof Cu_2O nano-particles in polymer matrix and the mechanical properties of corresponding fibers were char-acterized by infrared spectrum, scanning electron microscope and monofilament tensile strength tester, re-spectively. The results show that the distribution of Cu_2O nano-particles(200 nm) on the surface of the com-posite fiber is more uniform when they are prepared via in situ polymerization. The tensile fracture strengthof composite fiber prepared by in situ polymerization can reach about 3.8 c N/dtex which increases by 47%~72% than that prepared by melt blending method. Moreover, the obtained corresponding PET/Cu_2O nano-composite fiber exhibites good antibacterial properties and the antibacterial rate of which can reach 99.73%with the dosage of Cu_2O nano-particle at 0.2%.
