Silk fibroin membranes and polyethylene films have been fluorinated by CF4 (tetra-fluoromethane) lowtemperature plasma on conditions that CF4 gas flow rate was 30mL/min, treatment time was 2 minutes, and discharge power variation was 30_??_400W, followed by being immersed inpure water. Fluorine atom in their samples before and after extraction test, and fluoride ion in the extracted water were quantitatively analyzed. Surface component of their samples before and after extraction was also analyzed by XPS. As a result, fluorine containing groups being soluble in water were formed only by the fluorination of silk fibroin membranes. The effect of the surface structrure change of fluorinated silk fibroin membranes on the water swelling ability, the water contact angle and the dyeability were examined. As a result, the hydrophobicity and the water contact angle increased, and the water swelling ability decreased with increasing of the fluorine fixation content. After extraction, decreasing of the water contact angle was found, which suggested hydrolysis of fluoride acid end groups (-COF). Moreover, the primary amino group formation by the decomposition of peptide bonds was also suggested and it was supposed that this amino group caused the increase of the dyeability by acid colors.
