对棉织物进行改性，使其具有超疏水、自洁和耐热性，在实际应用中具有特别的意义。本文设计了一种简单的表面改性路线，在棉织物表面引入阻燃组分9,10 -二氢-9-氧-10-磷酸菲-10-氧化物（DOPO）和含有氟和硅元素的低表面能交联聚合物网络。改性棉织物具有超疏水性，水接触角达到154.8度，具有良好的自清洁性能。改性棉织物具有疏水性和亲脂性，能有效分离油水混合物和乳液。此外，DOPO和含氟硅涂层的引入不仅提高了棉的耐热性，而且提高了棉的阻燃性能。
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 degrees, 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.
