THIN-FILM CHARACTERISTICS OF FLUORINE-SUBSTITUTED MONOLAYERS PREPARED BY CHEMICAL ADSORPTION FROM SOLUTION

Monolayers containing a fluorine-substituted carbon chain were prepared by the chemical adsorption (CA) technique. Characteristics of the monolayers were evaluated by spectroscopy, copper decoration technique, current-voltage characteristics (current density and resistivity), measurement of the contact angle, and friction tests. By the copper decoration technique, the CA monolayer was more pinhole free and uniform than a Langmuir-Blodgett film. The characteristics (such as the leakage current density, resistivity, critical surface tension and coefficient of kinetic friction) of the fluorine-substituted monolayers depended markedly on the number of substituted fluorine atoms.
