Control of particle size and surface properties of fluorinated acrylate microemulsion

Fluorinated acrylate microemulsion was prepared via co-polymerising methyl methacrylate, butyl acrylate and dodecafluoroheptyl methacrylate that were stabilised by polyethylene glycol mono- p-nonyl phenyl ether and sodium dodecyl benzene sulphonate and initiated by potassium persulphate. Many factors, which had an influence on the particle size and its distribution, had been investigated. It was possible to produce nanoparticles <100 nm and with narrower size distributions using the semicontinuous seeded emulsion polymerisation. Fourier transform infrared spectroscopy confirmed the structure of the microemulsion. The appearance of the microemulsion was translucent and accompanied with blue fluorescence. The stability of the microemulsion was very high. The solid content of the microemulsion was 38·65%. The contact angle of the film was not very high.
