Preparation of Superhydrophobic Cotton Fabric and Its Pollution Resistance
In order to solve the problem that cotton fabric is easy to be polluted in daily life,nano silver was deposited on the surface of cotton fabric,combined with dodecyl mercaptan modification,the super hydrophobic cotton fabric with excellent stain resistance was prepared.The surface microstructure and hydrophobicity of super hydrophobic cotton fabric were characterized and measured by scanning electron microscope and contact angle tester.The results showed that the surface of the superhydrophobic cotton fabric was modified with a layer of irregular micro and nano structure of silver,and the surface contact angle reached 156°,showing excellent superhydrophobicity.At the same time,the anti-fouling experiment results showed excellent anti-fouling and anti-bacterial effect,and the antibacterial rates of Staphylococcus aureus and Escherichia coli were 92%or above.In addition,the stability experiment results showed that the hydrophobicity and stain resistance of the surface did not change greatly after different wear,and it had a certain ability to resist acid and alkali.
