フッ素重合体上の接着層を含むデバイス、およびそのようなデバイスの製造方法

Japanese Patent JP5430094

B2

A device comprises layer made from fluoropolymer (4), of which at least part of surface is covered with composition containing polymer having at least one fluorinated function and at least one acid or base function and forming bonding layer (6) on fluoropolymer, where bonding layer is fully/partly covered by another layer. The composition forming bonding layer further has compound interacting with acid/base function, or material of interest such as resin, ink or dielectric. The layer covering bonding layer is electrode, semiconductive material, dielectric, ink layer or adhesive layer (8). A device comprises a layer made from a fluoropolymer (4), of which at least part of the surface is covered with a composition containing a polymer having at least one fluorinated function and at least one acid or base function and forming a bonding layer (6) on the fluoropolymer, where the bonding layer is fully or partly covered by another layer. The acid function is provided by a carboxylic, phosphonic, sulfonic, sulfone or Si(CH 3) 3function. The base function is provided by an amine. The monomer having at least one fluorinated function is of the same type as the monomer present in the fluoropolymer. The fluorinated function and the acid or base function are carried by the same monomer. The fluoropolymer is polytetrafluoroethylene (PTFE) or Cytop(RTM: polyperfluorobutenyl vinyl ether). The polymer having at least one fluorinated function and at least one acid or base function is Nafion(RTM: polymer), Hyfion Ion(RTM: polymer) or Flemion(RTM: polymer). The composition forming the bonding layer further comprises a compound capable of interacting with the acid or base functions of the polymer; or a material of interest such as resin, an ink or a dielectric. The layer covering all or part of the bonding layer is an electrode, a semiconductive material, a dielectric, a layer of ink or a layer of adhesive (8). An independent claim is included for fabricating the device involving: a step of deposition, on at least part of the outer surface of a fluoropolymer layer, of a composition comprising a polymer having at least one fluorinated function and at least one acid or base function and forming a bonding layer after drying; and a step of deposition of another layer on this bonding layer. The depositions are carried out by dip-coating, spin-coating or printing. The composition comprising a polymer having at least one fluorinated function and at least one acid or base function contains a solvent (preferably isopropanol).
