摘要
以自制纳米银为抗菌剂,无纺布为基材,采用传统的浸渍法制备抗菌织物。再采用浸渍法将自制的含氟聚倍半硅氧烷整理到无纺布上,制备出自修复超疏水抗菌织物。探究了浸渍时间和含氟聚倍半硅氧烷质量浓度对织物超疏水性能影响以及超疏水织物的自修复性、耐摩擦和抗菌性。结果表明,在含氟聚半倍硅氧烷溶液(5 mg/mL)中浸渍2 h,织物的接触角可达173.69°,具有良好的超疏水性;织物经4次氧等离子刻蚀与在温度25℃,湿度99%条件下修复循环后,织物表面的水接触角仍能达到168.99°;通过比浊法测试菌液的OD600吸光值,含有抗菌织物的菌液OD600值小于对照组菌液OD600值,表明织物具有良好的抑菌效果;织物经过300次摩擦,织物表面的水接触角仍能达到169.89°,表明织物具有良好的耐摩擦性能。
The antibacterial fabric was prepared via a convenient solution-dipping method with self-made silver nanoparticles as antibacterial agent and non-woven fabric as base material.And the self-healing superhydrophobic antibacterial fabric was prepared by coated self-made fluorinated polysiloxane(F-POSS)via a convenient solution-dipping method.The effects of dipping time and concentration of F-POSS on the superhydrophobic properties of fabrics,as well as the self-healing,friction resistance and antibacterial properties of fabrics were investigated.The experimental results showed that the contact angle of the fabric could reach to 173.69°after dipped into F-POSS solution(5 mg/mL)for 2 h,indicating the good superhydrophobicity.After etched four times by oxygen plasma and the healing cycle at 25℃and 99%humidity,the water contact angle on the fabric surface still reach 168.99°.The OD600 absorbance value of bacterial solution was tested by turbidimetry mehod,and the OD600 value of bacterial solution containing antibacterial fabric was lower than that of control group,indicating that the fabric had good antibacterial effect.After 300 times of abrasion,the water contact angle on the fabric surface still reached 169.89°,indicating that the fabric had good friction resistance.
