The effect of fluoro-compound on superamphiphobic materials were characterized. As a test sample, superhydrophobic silica obtained by sol-gel methods was used. By addition of a little amount of C6F13C2H4OH, we could obtain high oleophobic materials without the loss of hydrophobicty. To get the evidence of furorine reaction FT-IR spectrum was characterized and we could confirm C-F bond. As the wt% of fluorine alcohol was increased, the contact angle for CH2I2 and surface free energy were increased. But the both properties the were decreased by the excess addition of fuorine alcohol over 0.1wt%. |
