As an emerging area in organic electronics, polymer memories have become active research topic recent years. Polymer based on bistable electrical switching are likely to be alternative or supplementary technology the conventional memory facing problem miniaturizing from micro- nano-scale. In this article, account of our work a series processable electroactive polymers is given. The can provide required electronic properties within single macromolecule for device applications. Bistable phenomena arising four processes, viz., trapping–detrapping, charge transfer, conformational change and nanocomposite redox effects, described. each case, three aspects effect, (i) materials structural features, (ii) conductance current–voltage characteristics, (iii) operating mechanism transitions emphasized. Finally, performance these summarized.
