中文摘要：为了研究纳米铜对聚酰胺纤维化学结构、热学性能、晶体结构和力学性能的影响,采用扫描电子显微镜、傅里叶变换红外光谱仪、X-射线衍射仪、热重分析仪、差示扫描量热仪对纳米铜含量为0.5%的聚酰胺纤维和普通聚酰胺纤维进行了表征,并探究了纤维结构与纤维机械拉伸性能间的关系。结果表明:负载纳米铜不影响聚酰胺纤维化学结构;聚酰胺纤维中少量小分子物质可在纳米铜作用下加速分解;与普通聚酰胺纤维相比,纳米铜抗菌聚酰胺纤维主要分解起始温度较高,残炭含量较少,熔点、结晶温度和结晶度较高,晶粒尺寸较小,晶面间距较大,拉伸强力和断裂伸长率较高,但初始模量较低,且机械性能的变异系数较大。

外文摘要：In order to evaluate the effects of copper nanoparticles on the chemical structure,thermal properties,crystal structure and mechanical tensile properties of polyamide fibers,both the polyamide fibers containing 0.5%nano-copper and the ordinary polyamide fibers were characterized by scanning electron microscope,Fourier transform infrared spectrometer,X-ray diffraction,thermogravimetric analyzer and differential scanning calorimeter.And the relationship between structure and mechanical tensile properties was also explored.The results show that copper nanoparticles embedded in polyamide matrix did not affect the chemical structure of the fibers.The decomposition of a few small molecules in polyamide fiber can be accelerated by nano-copper.Compared with ordinary polyamide fibers,the primary decomposition of antibacterial polyamide fiber start at a higher temperature,and the residual carbon content is lower.The antibacterial polyamide fiber has higher melting point,crystallization temperature and crystallinity,smaller crystal size,larger crystal surface spacing,higher tensile strength and breaking elongation,while the initial modulus is lower,and the variable coefficients of mechanical properties are larger.
