Abstract
The spreading behaviors of poly(N-decylacrylamide-co-N-1H,1H-pentadecafluorooctylacrylamide) (DAPF) copolymers with various copolymer compositions at the air–water interface were investigated by measurement of surface pressure–surface area isotherms to prepare a high quality fluorinated polymer Langmuir–Blodgett (LB) film for developing a new type of solid lubricant. The monolayer property depended strongly on the copolymer composition. The copolymer monolayers can be transferred onto solid substrates giving uniform polymer LB films. The surface wettability and the critical surface tensions of the LB films were investigated by measuring the contact angle (θ) of a water droplet on the surface. The friction coefficients of the LB films were measured as a function of the copolymer composition. The friction coefficient for the DAPF copolymer LB films decreases with the content of N-decylacrylamide (DA). The frictional properties in the copolymer LB films are discussed from various factors, such as packing density and chemical composition.
