ABSTRACT:
Using the Langmuir-Blodgett's technique and a compound represented by the general formula CF.sub.3 (CF.sub.2).sub.n (CH.sub.2).sub.m --X, wherein X is a hydrophilic group, preferably --COOH, n is from 5 to 20 and m is from 0 to 10, a firm built-up film having a desired number of monomolecular layers can surely be formed on a solid substrate surface by spreading a monomolecular film of the fluorinated compound on an aqueous phase containing trivalent metal ions. In the obtained built-up film the CF.sub.3 -terminated molecules are well oriented in the direction of the thickness of the film. The built-up film fully exhibits extreme hydrophobicity, high insulation, low refraction and other properties characteristic of the fluorine-containing compound.
