Preparation and characteristics of perfluorodiacetylene Langmuir-Blodgett films
The surface pressure-area curve for the novel perfluorodiacetylene, C24F42, showed that a monolayer was formed on the surface of the water. The monolayer was deposited on KRS-5, Al and quartz plates by the Langmuir-Blodgett (LB) technique. The LB film on the KRS-5 plate showed excellent water repellency with a contact angle of 162 degrees. Comparison of the reflection-absorption and transmission i.r. spectra showed that the difluoromethylene chains in the C24F42 LB film were oriented perpendicular to the substrate surface. The C24F42 LB film on the quartz plate was polymerized by u.v. irradiation giving a highly electroconductive film without doping or further treatment.
