Abstract: | The fluorinated poly(trifluoroethylmethacrylate) thin polymers were successfully prepared through free radical initiating admicellar polymerization approach using fluorosurfactant and 2,2,2-trifluoroethylmethacrylate (TFEM, monomer) system, which was initiated with potassium persulfate (KPS) initiator. The structure of the resultant polymer and morphology of the modified cotton fabric surfaces were confirmed by SEM and EDX analysis. The surface wettability of the modified cotton fabric was characterized by a water drop stay time and contact angle (CA) measurement. The coated cotton fabric exhibited excellent hydrophobicity with a water contact angle of 137.79°. |
