通过浸涂-水热法制备具有松针状仿生结构的氧化锌涂层聚丙烯(ZnO@PP)非织造材料，并对该材料的表面形貌、化学结构、晶体结构、力学性能、液体处理性能进行测试与表征，还进一步开展了生物相容性、止血性能及抗菌性能评估。结果表明：ZnO纳米棒成功在聚丙烯纤维表面“生长”,形成了松针状仿生结构。该ZnO@PP非织造材料展现出更高的拉伸应力、优异的柔韧性、良好的亲水性及液体吸收扩散性能，同时具有良好的细胞和血液相容性。体外全血凝固试验表明，ZnO@PP非织造材料所需的凝血时间为(142.00±4.95)s,与PP非织造材料相比缩短了76.53%。该材料对大肠埃希菌和金黄色葡萄球菌的抗菌活性分别达到(99.10±0.53)%和(97.28±0.64)%,其在抗菌止血领域具有良好的应用前景。
Abstract：Zinc oxide-coated polypropylene(ZnO@PP) nonwovens with a pine-needle-like bionic structure were prepared by dip-coating and hydrothermal method. The surface morphology, chemical structure, crystal structure, mechanical properties, liquid handling performance of the nonwovens were tested and characterized. And biocompatibility, hemostatic performance, and antibacterial performance were further evaluated. The results showed that ZnO nanorods successfully ‘grew' on the surface of polypropylene fibers, forming a pine-needle-like bionic structure. The ZnO@PP nonwovens exhibited higher tensile stress, excellent flexibility, good hydrophilicity, and liquid absorption and diffusion property, as well as good cell and blood compatibility. The in vitro whole blood coagulation test showed that the coagulation time for ZnO@PP nonwovens was(142.00±4.95)s, which was shortened by 76.53% compared with that of PP nonwovens. The antibacterial activities of the material against E. coli and S. aureus reached(99.10±0.53)% and(97.28±0.64)%, respectively. It has good application prospects in the field of antibacterial and hemostatic.
