Abstract
This invention concerns an electrochromic pane comprising a principal functional film constituted of a material which, under the effect of an electric current, is capable of reversibly inserting cations and which has characteristics of coloration and/or transmission in certain wavelengths of electromagnetic radiation that differ for its inserted and deinserted states. Said principal functional film has a quasi-columnar structure, with axes of growth of the columns parallel to straight lines contained within a dihedron, the opening of which is less than 20.degree., and the bisector plane of which makes an acute angle with the substrate.
