PASTE AND POLYMER TRANSDUCER INCLUDING COATING FILM FORMED FROM SAME AS ELECTROLYTE FILM OR ELECTRODE FILMS

摘要

A paste which can be prepared at an arbitrary solid content concentration and which is excellent in handling properties, coating properties and storage stability, and an electrolyte which is a coating film formed with a desired film thickness having uniformity and excellent flexibility by a process of coating and drying the paste a small number of times A membrane electrode film, and a polymer transducer which can be industrially and economically realized and exhibit excellent performance. The paste contains a polymer block (a-1) containing a unit represented by the formula (1) and a polymeric solid (a-1) comprising a block copolymer containing substantially no ionic group and a polymer block (C) insoluble in the organic solvent (B), having a long diameter of 1 to 100 mu m and an aspect ratio of 5 or less, an electrolyte (A), an organic solvent (B) having a boiling point of 150 DEG C or higher, In the polymer transducer, either the electrolyte membrane or a pair of electrode films sandwiching the electrolyte membrane is formed into a film shape by drying and solidifying the paste.
