摘要：
The influence of the ozone-gas treatment on the performance of the fluorocarbon monomer on cotton fiber was investigated employing Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermo-gravimetric analysis (TGA), scanning electron microscopy (SEM), water contact angle (WCA) and bending length (BL). FTIR results indicated that the ozone-gas pre-treatment oxidized the surface of the fibers increasing reactivity of the substrate toward the fluoromonomer. The contact angle and microscopic tests showed that the combination of ozone and fluorocarbon treatments on cotton can increase the contact angle due to higher efficiency of the water repellent polymer on the surface of the ozone-gas treated fibers. The results obtained from the weight of the samples verified the successful grafting of the fluoromonomer on the cotton fabrics. (c) 2012 Elsevier Ltd. All rights reserved.
