  Superhydrophobic Fiber Mats by Electrodeposition of Fluorinated Poly(3,4-ethyleneoxythiathiophene)

  摘要：

  The control of surface morphology and wettability is crucial in the development of superhydrophobic surfaces, which implies new strategy and molecular design. In this Article, we report the synthesis, characterization, and electrochemical properties of original 3,4-ethyleneoxythiathiophenes (EOTT) as platform molecules and its derivatives bearing a semifluorinated chain of various length (F-octyl, F-hexyl, F-butyl, and F-ethyl). We report the influence of the fluorinated chain length as well as the presence of sulfur atoms in the monomer on the surface construction and nonwetting properties of the corresponding electrodeposited polymer films. Surprisingly, these films exhibit the possibility to obtain extremely long polymer fibers with a possible control of their length by a careful choice in the monomer structure. We show that the presence of sulfur atoms in the monomer structure seems to be necessary to modulate the formation of extremely long polymer fibers by aggregation of smaller polymer fibrils. In this Article, the formation of superhydrophobic material (contact angle above 150 degrees) for four, six, and eight fluoromethylene units but also highly hydrophobic surfaces (contact angle above 125 degrees) from extremely short chains (two fluoromethylene units) is also demonstrated.

  The invention relates to a multilayer superoleophobic and/or superhydrophobic material comprising: on the one hand, a first constituent that is a conductive substrate or a substrate that has previously been rendered conductive (1): the surface of which is modified by chemical and/or physical treatment (2) and that incorporates a first adhesion-promoting conductive layer (3); or that incorporates a first adhesion-promoting conductive layer (3); and, on the other hand, at least one other constituent that is a superoleophobic and/or superhydrophobic polymer or copolymer layer (4, 5 or 6) composed of one or more monomers based on an aromatic or heteroaromatic ring substituted by one or more fluorocarbon and/or hydrocarbon chains. It is characterized in that the various constituents of said material comply with an increasing hydrophobicity gradient between the first layer deposited on the conductive substrate or substrate previously rendered conductive (1) and the last layer of said material.
