| Résumé : |
The effect of film formation temperature on the internal structure of self-organised films of fluoroacrylate/polyacrylate emulsions is described. Six fluorinated polyacrylate emulsions bearing varying fluorinated monomers were prepared and blended with the same polyacrylate emulsion. The blends were dried at 30°C, 45°C and 60°C. The minimum film formation temperature (MFFT) was tested by the MFFT-BAR-60 model instrument. The surface properties and morphologies of the blends on both the film-air (F.-A) and the film-glass (F-G) interfaces were characterised by contact angle, particle size distribution and scanning electron microscopy. The elemental composition and structure of films across the section were analysed by scanning electron microscope with energy dispersive X-ray spectroscopy (SEM-EDX) and X-rayphotoelectron spectra (XPS) analysis. |
