Abstract
A process used to cast films including: mixing BBL and a room temperature molten salt from a range of about 35:65 weight ratio, dissolving the mixture in about 1% methanesulfonic acid to produce a BBL solution, drop casting the solution onto glass or gold coated glass at 140° C. in air and heating for about 2 hours to produce films, drying the films in a vacuum oven at about 100° C. for at least 24 hours under dynamic vacuum, and rinsing the films to remove residual ionic liquid.
Claims15
An electroactive polymer-based supercapacitor, comprising:
- at least two electrodes configured to store charge, wherein at least one electrode is an anode and at least one electrode is a cathode, wherein said cathode having BBL or Pry-BBL;
- at least one electroactive polymer associated with each said electrode;
- and
- at least two ionic liquid electrolytes, wherein each said polymer separates said ionic liquid electrolytes from each said electrode, wherein said mixture of at least two ionic liquid electrolytes maintains a liquid state down to −60° C.
