Definitions
- the present invention relates to the use of a fluorinated copolymer in the manufacture of a solid polymer film, to impart to said film adhesion properties on a metal or polymeric surface or on glass. It also relates to a method for improving the adhesion to a metallic, polymeric or vitreous substrate of a fluorinated polymer, as well as a composite part comprising a solid polymer film in direct contact with at least one metallic or vitreous element.
- Metallized polymer films have many applications, especially in the manufacture of electrically conductive devices.
- fluorinated polymers based in particular on vinylidene fluoride (VDF) represent a class of compounds having remarkable properties for a large number of applications.
- PVDF and copolymers comprising VDF and trifluoroethylene (TrFE) are particularly interesting because of their piezoelectric properties. They can thus be used for the manufacture of various electroactive equipment, such as actuators or sensors, generally comprising a film of the polymer sandwiched between two electrodes.
- an essential condition for obtaining the desired result is the good adhesion of the polymer to the metal.
- This property is particularly important for the manufacture of electroactive devices. Indeed, the good adhesion of the polymer to a metal electrode simplifies the manufacturing process of these devices by rendering unnecessary the preliminary stage of treatment of the electrode (especially with the aid of chromium) in order to promote the adhesion of the electroactive polymer. It also makes it possible to manufacture multilayer devices without risk of delamination or loss of electrical conductivity.
- VDF copolymers are also known with monomers bearing phosphonic acid functional groups, such as vinylphosphonic acid (WO 2012/030784, US2012 / 0184653 and WO 2014/162080). It is not suggested that the copolymers described in these documents exhibit remarkable adhesion to metals and / or glass.
- the vinyl phosphonic co-monomer represents at least 1 mol%, and preferably 2 to 18 mol%, of the copolymer of WO 2014/162080.
- Another adhesion promoter monomer which has been copolymerized with VDF is trifluoromethacrylic acid (JP2003-040936). However, it is not suggested that it can improve the adhesion to metal substrates or to glass of VDF and TrFE-based copolymers, especially when it is introduced into these copolymers in small amounts, less than or equal to at 1 mol%.
- the invention thus relates to the use of a fluorinated copolymer in the manufacture of a solid polymer film, for imparting to said film adhesion properties on a metal surface or on glass, characterized in that said copolymer is obtained by :
- (a) radical copolymerization of monomers comprising, and preferably consisting of: (i) vinylidene fluoride (VDF), (ii) trifluoroethylene (TrFE), (iii) optionally at least one other fluorinated monomer and (iv) a adhesion promoter monomer which is a non-perfluorinated vinyl or vinylenic monomer carrying at least one weak acid function or weak acid precursor, at with the exception of carboxyvinyl, carboxyvinylene, 1-alkylcarboxyvinyl, 1-alkylcarboxyvinylene monomers and their precursors, and
- the invention also relates to a process for improving the adhesion to a metallic, polymeric or vitreous substrate of a fluorinated polymer obtained from monomers comprising or preferably consisting of vinylidene fluoride (VDF), trifluoroethylene (TrFE) and optionally at least one other fluorinated monomer, characterized in that it comprises introducing into said fluoropolymer units resulting from the radical copolymerization of a non-perfluorinated vinyl or vinylenic monomer carrying at least one weak acid function or precursor d weak acid, with the exception of carboxyvinyl, carboxyvinylene, 1-alkylcarboxyvinyl, 1-alkylcarboxyvinylene monomers and their precursors, and the conversion of the weak acid to weak acid precursor function, when present.
- VDF vinylidene fluoride
- TrFE trifluoroethylene
- a composite part comprising a solid polymer film in direct contact with at least one metallic, polymeric or vitreous element, characterized in that said film is made from a copolymer obtained by:
- (a) radical copolymerization of monomers comprising, and preferably consisting of: (i) vinylidene fluoride (VDF), (ii) trifluoroethylene (TrFE), (iii) optionally at least one other fluorinated monomer and (iv) a adhesion promoter monomer which is a non-perfluorinated vinyl or vinylenic monomer bearing at least one weak acid function or weak acid precursor, with the exception of carboxyvinyl, carboxyvinylene, 1-alkylcarboxyvinyl, 1-alkylcarboxyvinylene monomers and their precursors, such that the molar proportion of the units derived from said adhesion promoter monomer is less than 1% of the copolymer, and
- these copolymers have a polarization curve similar to that of polymers lacking adhesion promoting monomer, namely the same remanent polarization, the same coercive field and the same hysteresis.
- the range of uses of these fluorinated polymers, modified according to the invention by the introduction of an adhesion promoter monomer is not limited by the introduction of this monomer.
- Figure 1 illustrates the radical terpolymerization of VDF with TrFE and DMVP and the hydrolysis of the obtained terpolymer.

- the invention relates to the use of a fluorinated copolymer in the manufacture of a solid polymer film, to impart to said film adhesion properties on a metal or polymeric surface or on glass.
- the fluorinated copolymer used in this invention comprises a unit derived from vinylidene fluoride (VDF) and a unit derived from trifluoroethylene (TrFE). It also optionally contains at least one other unit derived from a fluorinated monomer, which may especially be chosen from: tetrafluoroethylene (TFE), chlorofluorethylene (CFE), chlorotrifluoroethylene (CTFE), hexafluoropropylene (HFP), trifluoropropene, tetrafluoropropene, chloro-trifluoropropene, hexafluoroisobutylene, perfluorobutylethylene, pentafluoropropene, perfluoroethers such as PMVE and PPVE, and mixtures thereof.
- TFE tetrafluoroethylene
- CFE chlorofluorethylene
- CTFE chlorotrifluoroethylene
- HFP hexafluoropropylene
- This fluoro homopolymer or copolymer does not in itself exhibit good adhesion properties on polar hydrophilic surfaces such as metal surfaces or glass.
- patterns derived from an adhesion promoter monomer are introduced into this polymer.
- the aforementioned monomers are copolymerized, by radical copolymerization, with an adhesion promoter monomer which is a non-perfluorinated vinyl or vinylenic monomer carrying at least one weak acidic function or weak acid precursor.
- the adhesion promoter monomer carries a weak acid precursor function
- the copolymerization step is followed by a step of converting the weak acid precursor functions into weak acid functions.
- the weak acid function of the adhesion promoter monomer is advantageously chosen from a carboxylic acid function and a phosphonic acid function. When this monomer carries several (usually two or three) weak acid functions, these may be the same or different. In a preferred embodiment of the invention, the adhesion promoter monomer carries a single weak acid function.
- this monomer is distinct from a carboxyvinyl, carboxyvinylene, 1-alkyl-carboxyvinyl, 1-alkylcarboxyvinylene monomer and their precursors.
- acrylic acid, methacrylic acid and their esters are not included among the adhesion promoter monomers useful in the present invention.
- this carboxylic acid function be carried on a vinyl monomer bearing an electron withdrawing group such as a trifluoromethyl group.
- the adhesion promoter monomer carries at least one weak acid precursor function, in particular a carboxylic acid precursor or, more preferably, a phosphonic acid precursor.
- Such precursors are, in particular, carboxylic acid salts and alkyl esters and phosphonic acid salts and alkyl esters.
- it is preferred to use phosphonic acid alkyl esters. of the Examples of such functions are the monoalkyl ester and dialkylester functions and preferably phosphonic acid dialkyl esters, such as the methyl, ethyl or isopropyl esters of phosphonic acid, more particularly the methyl phosphonic acid esters.
- a vinyl monomer carrying such functions is in particular vinylphosphonic acid dimethyl ester (DMVP).
- adhesion promoter monomer can carry both a weak acidic function and a weak acid precursor function, chosen from those described above.
- the preferred adhesion promoter monomers according to this invention are chosen from a dialkyl ester of vinylphosphonic acid, in particular vinylphosphonic acid dimethyl ester, vinylphosphonic acid and (2-trifluoromethyl) acrylic acid.
- the molar mass of the adhesion promoter monomer is for example between 100 and 250 g / mol, preferably between 100 and 200 g / mol.
