Cellulose fabric is susceptible to water contamination and can even breed bacteria in the process of using. In order to reduce the influence of pollutants on the performance of the fabric

it is necessary to modify it for anti-pollution. In this study

the cellulose fabric is treated sequentially in dopamine and copper sulfate solution

copper ions are reduced to copper element by sodium borohydride

and the treated fabric is immersed in the hexadecyltrimethoxysilane(HDTMS) solution to prepare the fabric with anti-pollution properties. The results show that the contact angle of the resultant antipollution fabric is 155°

which meets the requirements of a superhydrophobic surface

and the antibacterial rates against both E.coli and S.aureus have reached 99.9%. After 24 h of ultrasonic treatment

the fabric still maintains stable antipollution performance. The anti-pollution fabric prepared in this article has both water-resistant pollution and biodegradable characteristics

and it is expected to expand its application in the medical and health field.
