摘要
为制备一种可生物降解型抗菌纳米纤维膜,对PHBV与PBAT混纺纺丝液的质量分数和质量比以及加入抗菌剂纳米TiO_(2)的质量分数进行探究。通过扫描电子显微镜、傅立叶红外光谱、差示扫描量热分析、力学性能测试和亲水性能测试,结果表明,PHBV/PBAT质量比为50∶50、质量分数为13.0%时纳米纤维膜具有良好纤维形态并具备一定的力学性能和疏水性。其中添加1.0%的TiO_(2)的PHBV/PBAT/TiO_(2)纳米纤维膜的断裂伸长率由137.5%增加到203.1%,并且疏水性显著提高。抗菌结果表明,其具有优异的抗菌性能,对大肠杆菌和金黄色葡萄球菌的抑菌率高达98.0%以上。
In order to prepare a biodegradable antibacterial nanofiber membrane,the mass fraction and mass ratio of PHBV and PBAT blended spinning solution and the mass fraction of nano TiO_(2)added with antibacterial agent are investigated and analyzed.The results of SEM,FTIR,DSC,mechanical property testing and hydrophilic property testing show that when the PHBV/PBAT mass ratio is 50∶50 and the mass fraction is 13.0%,the nanofiber membrane has good fiber morphology,mechanical properties and hydrophobicity.The elongation at break of PHBV/PBAT/TiO_(2)nanofiber membrane added with 1.0%TiO_(2)increases from 137.5%to 203.1%,and the hydrophobicity is significantly improved.The results of antibacterial testing show that the antibacterial properties are excellent,and the antibacterial rate against E.coli and S.aureus can reach 98.0%.
