SilanesIndex. décimale : 667.9 Revêtements et enduits Résumé : Imparting oil and water repellency on surfaces is easily achieved with the use of fluoroalkyl-modified silanes. Whilst perfluoroalkyl-modified silanes exhibit high static and advancing water and oil contact angles, their low receding contact angles mean that water and oil will not readily slide over treated surfaces. However, modified perfluoropolyether (PFPE) silanes, whilst exhibiting high static and advancing water and oil contact angles, also exhibit high receding contact angles, resulting in surfaces where the sliding contact angle is very low. The influence of structure modification of the silane and the perfluoropolyether component are examined along with the organic linking group. Their impact on performance using both the dip coating method and the chemical vapour adsorption method is discussed.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : A series of UV-curable fluorinated polycarbonate polyurethanes (FCPUAs) were synthesized by modifying polycarbonate polyurethane with 2-(perfluorohexyl)ethanol (PFHE) and glycidyl methacrylate (GMA). The structures of FCPUAs were analyzed with 1H NMR and FTIR. Different contents of FCPUAs were blended into non-fluorinated polycarbonate polyurethane as fluorinated additives. The water and oil contact angles of the films were investigated by contact angle measurement, and the results indicated that an extremely low concentration of FCPUAs could produce a highly hydrophobic and oleophobic coating. The X-ray photoelectron spectroscopic analysis showed that the coating surface was rich in fluorinated species. Besides, the films containing FCPUAs also had great tensile strength, hardness and adhesion.
