Title:
PASTE AND POLYMER TRANSDUCER INCLUDING COATING FILM FORMED FROM SAME AS ELECTROLYTE FILM OR ELECTRODE FILMS
Document Type and Number:
WIPO Patent Application WO/2012/039425
Kind Code:
A1
Abstract:
[Problem] To provide: a paste which can be prepared so as to have any solid concentration and is excellent in terms of handleability, applicability, and storage stability; an electrolyte film or electrode film which is an even and highly flexible coating film formed in a desired thickness from the paste through a few repetitions of an application/drying step; and a polymer transducer which can be industrially produced economically and shows excellent performance. [Solution] A paste comprises: a solid polyelectrolyte (A) comprising a block copolymer that comprises a polymer block (a-1) which contains a unit represented by chemical formula (1) and a polymer block (a-2) which has substantially no ionic group and is rubbery at room temperature; an organic solvent (B) having a boiling point of 150ºC or higher; and non-dissociable particles (C) which are insoluble in the organic solvent (B) and have a major-axis length of 1-100 µm and an aspect ratio of 5 or less. The polymer transducer comprises an electrolyte film and a pair of electrode films between which the electrolyte film is sandwiched, wherein the electrolyte film or the pair of electrode films has been formed by drying and solidifying the paste into a film shape.
