Abstract:
Modification of cotton fabric to achieve superhydrophobic, self-cleaning and heat resistance is of particular interest for practical applications. Herein, a simple surface modification route is designed to introduce flame retardant component 9, 10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO) and low surface energy crosslinked polymer network comprising both fluorine and silicon elements on the surface of cotton fabric. The modified cotton fabric shows characteristic of superhydrophobic property with water contact angle of 154.8°, and exhibits promising self-cleaning performance. With the characters of hydrophobicity and lipophilicity, the modified cotton fabric can efficiently separate oil-water mixture and even emulsion. Moreover, the introduction of DOPO and fluorine-silicon-containing coating not only enhances the heat resistance of cotton, but also improves the flame retardant property.
