抗菌黏胶纤维的制备及性能研究
|
摘要
利用原位合成的方法,将金纳米粒子与黏胶纤维结合得到具有抗菌性能的黏胶纤维。使用X射线衍射仪(XRD)、傅里叶变换红外光谱仪(FTIR)、扫面电子显微镜(SEM)、热重分析仪(TGA)对纤维的结构和性能进行了分析并测试其抗菌性能,结果证明利用原位合成的方法成功地在黏胶纤维表面原位生成了金纳米粒子。金纳米粒子的生成使得纤维的表面光滑度下降;随着金纳米粒子含量的增加,纤维的热稳定性能提高;抗菌性能测试表明金纳米粒子的生成使得黏胶纤维表现出优异的抗菌性能。
Gold nanoparticles were prepared by in-situ synthesis and combined with viscose fiber to prepare antibacterial viscose fiber.The structure and properties of antibacterial viscose fiber was investigated by X-ray diffractometer(XRD),Fourier transform photoelectron spectrometer(FTIR),scanning electron microscopy(SEM),thermogravimetric analysis(TGA).The antimicrobial properties were tested.The results indicated that gold nanoparticles were combined with viscose fibers by in situ synthesis.Because of the formation of gold nanoparticles,the smoothness of surface of fiber was decreased.The thermal stability of the fiber was improved with the increase of gold nanoparticles.Through the antibacterial performance test,it was found that the viscose fiber which combined with gold nanoparticles had excellent antibacterial properties.
