We describe methods for coating fluoropolymer surfaces with thin films
of electronically conductive polymers. Modification of the fluoropoly
mer surface prior to coating with conductive polymer is necessary to a
chieve good adhesion between the fluoropolymer membrane and the conduc
tive polymer coating. We describe four different procedures for modify
ing the fluoropolymer surface so as to promote strong adhesion. These
procedures are based on a wet chemical treatment of the fluoropolymer
or on exposure of the fluoropolymer surface to a hydrogen plasma, an u
ltraviolet laser or an electron beam. Finally, we show that it is poss
ible to 'write' patterns with the conductive polymer onto the fluoropo
lymer surface.
