专利汇可以提供Electric color forming element专利检索,专利查询,专利分析的服务。并且PURPOSE: To eliminate the need for sealing port and prolong the coloring-decoloring repetition life of the element by using transition metal oxide as an electric color forming material layer and a perfluorosulfonic acid resin as an ion conducting material in forming the electric color forming material.
CONSTITUTION: A solid electric color forming material layer 3 of about 5000Å in film thickness composed of transition metal oxide such as WO
3 , MoO
3 , TiO
2 , etc. is formed by thermal evaporation, sputter evaporation, etc. on a transparent conductor film 2 of such as SnO
2 , In
2 O
3 , etc. formed on the surface of a transparent substrate 1, and a perfluorosulfonic acid resin (e.g., Naphion film 110, 120, 125, etc. Du Pont's trade name) layer 4 is laminated thereof. Further a thin film such as Au, Pt, etc. of high corrosion resistance and conductivity is provided as a counter electrode 5 thereon, whereby the electric color forming element is formed
