Definitions
- the invention relates to a fluoropolymer-based ink with improved adhesion to a substrate and to the use of this ink in the manufacture of electronic devices.
- Fluorinated polymers such as polyvinylidene fluoride (PVDF) and copolymers derived therefrom have a large number of uses, in particular wherein they are deposited as a film on a substrate.
- PVDF polyvinylidene fluoride
- the deposition of such fluoropolymers in film form can be performed from a formulation called "ink", consisting of a solution of the fluoropolymer, and optionally additives, in a good solvent.
- the invention firstly relates to a composition
- a composition comprising:
- polymer PF comprising units derived from vinylidene fluoride
- silane agent of formula S1R1 R2R3R4, in which R1, R2, R3 and R4 are chemical groups connected by single bond to the Si atom;
- the polymer PF also comprises units derived from at least one other monomer of formula wherein each group X1, X2, X3 and X 4 is independently selected from H, Cl, F, Br, I and alkyl groups comprising 1 to 3 carbon atoms, which are optionally partially or fully halogenated; and preferably the polymer PF comprises units derived from at least one monomer chosen from trifluoroethylene, tetrafluoroethylene, chlorotrifluoroethylene, 1,1-chlorofluoroethylene, hexafluoropropene, 3,3,3-trifluoropropene, 1, 3,3,3-tetrafluoropropene, 2,3,3,3-tetrafluoropropene, 1-chloro-3,3,3-trifluoropropene and 2-chloro-3,3,3-trifluoropropene.
- the polymer PF comprises units derived from trifluoroethylene, the proportion of units originating from trifluoroethylene being preferably from 15 to 55 mol% relative to the sum of the units derived from vinylidene fluoride and trifluoroethylene.
- the polymer PF further comprises units derived from an additional monomer, said additional monomer being preferably chlorotrifluoroethylene or 1,1-chlorofluoroethylene, and the proportion of units derived from the additional monomer being preferably from 1 to 20 mol%, more preferably from 2 to 15 mol%, based on all the units of the polymer PF.
- the polymer PF comprises units derived from hexafluoropropene, preferably in a proportion of 2 to 50 mol%, more preferably 5 to 40 mol%, relative to all the units of the polymer PF.
- the silane agent has a molecular weight less than or equal to 2000 g / mol, preferably less than or equal to 1000 g / mol, more preferably less than or equal to 500 g / mol, and more particularly lower or equal to 200 g / mol.
- R 1, R 2 and R 3 each represent a C 1 -C 4 alkoxy group, and R 4 represents a C 1 -C 10 alkyl group, optionally halogenated in whole or in part, and optionally comprising a terminal function, which preferably is chosen from among the functions amine, vinyl, (meth) acrylic and glycidyl; or
- the silane agent is a silazane.
- the silane agent is selected from 3-aminopropyltriethoxysilane, 3-glycidyloxypropyltriethoxysilane, 3-glycidyloxypropyltrimethoxysilane, fluoroalkylsilanes, vinyltrimethoxysilane, and combinations thereof.
- the PF polymer is present in a proportion of 70 to 99.99% by weight, and preferably in a weight ratio of 80 to 99.8% by weight; and the silane agent is present in a proportion of 0.01 to 30% by weight, and preferably 0.2 to 20% by weight; the proportions being given with respect to the sum of the polymer PF and the silane agent.
