ABSTRACT:
A method for preparing a processable polyisothianaphthene polymer includes steps of dissolving an isothianaphthene monomer in a solvent and introducing therein an initiator to initiate a polymerization reaction to produce a precursor of poly(dihydroisothianaphthene), dissolving thoroughly the precursor of poly(dihydroisothianaphthene) in the solvent in an appropriate ratio to obtain a poly(dihydroisothianaphthene) solution, proceeding a dehydrogenation reaction for the poly(dihydroisothianaphthene) solution by introducing a dehydrogenation agent to obtain a polyisothianaphthene microgel solution, and terminating the dehydrogenation reaction by introducing an inhibitor. This invention offers a simple, feasible, and economical way to prepare a large-area film with uniform film thickness, excellent stability, and good electrochromic, conducting, and mechanical properties.
