DEVICE INCLUDING A GLASS OR POLYMER SUBSTRATE COVERED BY A PVDF LAYER OR ONE OF ITS COPOLYMERS

摘要

Device comprising successively: - a substrate (104) made of glass or polymer, - a metallic pattern (108) locally covering the substrate, - a pyroelectric layer (200), the device further comprising, between the substrate (104) and the layer pyroelectric (200): -a first molecular layer (301) of general formula (I): Xm-A-Yn (I) -and / or a second molecular layer (302) of general formula (II): X'm ' -A'-Y'n '(II) -and / or a third molecular layer (303) of general formula (III): X''m' '- A' '- Y''n' '(III) with : A, A 'and A' 'an alkyl chain, X, X' 'an isocyanate group, an alkoxysilane group, or an amine group, X' a thiol group, Y, Y 'a fluorinated group or a hydrocarbon group, Y '' a thiol group, m, n, m ', n', m '' and n '' integers, ranging from 1 to 3, chosen independently of each other.
