1 . capacity and discharge efficiency of polyacene capacitors were systematically studies and electrolyte is aqueous and aqueous solution a series of pristine sample were prepared by pyrolysis of phenol formaldehyde resin moulded with znc , this inorganic salt used together with the resin served not only as the pore - forming agent to form open pores , which grow into a three - dimensional network structure in the cured material , but also as the microstructure - controlling agent to form a loose structure dopable with bulky dopants such as bf4 and so on
