Abstract
In this work, cotton was grafted with trifluoroethyl methacrylate (TFEMA) via atom transfer radical polymerization (ATRP) in water aqueous. The appearance of the cotton fabric was characterized with SEM, and SEM of the grafted cotton displayed significant difference from the ungrafted cotton. FT-IR indicated that TFEMA was successfully grafted onto surface of cotton fibers. Surface contact angle test and water repellency rating test showed that the water repellence of the modified cotton fabric were better than the ungrafted cotton fabric. Compared with the ungrafted cotton fabric, the whiteness, air permeability, breaking strength and elongation at break of the grafted cotton fabric decreased slightly. Grafted treatment led to efficient implantation of fluorine atoms on the surface of cotton fabric, this resulted in water repellence without altering the bulk properties of the cotton fabric.
