AiF research project "Super hydrophobic coating of filter cloths", Fkz: EP091924

(Term: Nov. 2009 - Oct. 2011)

Since the end of 2009, Rhenotherm has been involved in the BMWi-supported funding program ZIM (Central Innovation Program for SMEs, http://www.zim-bmwi.de/ ) specifically with the improvement of existing filter systems. This is to be achieved by coating wire meshes of different mesh sizes, which will consist primarily of fluoropolymers such as PTFE, PFA and FEP or of sol-gel materials. Here it is the coating by means of targeted structuring measures to give superhydrophobic properties and thus to produce a significantly improved filtering effect. The main application of these filters is the separation of liquid-liquid mixtures, but here are many other applications conceivable and to explore.
