摘要:
The present invention demonstrates the synthesis of a new pyrazole-containing monomer by means of an easily implemented two-step process. This monomer can be electropolymerized to yield a stable n-doping polymer that may easily be electrochemically characterized. It is demonstrated that the electrochemical behavior of the polymer films produced is dependent upon the conditions applied during electrodeposition. Films deposited by cycling only at relatively positive potentials (0 to 2000 mV) show less intense n-doping responses than those films obtained by scanning the applied potential throughout a wider range (−2000 mV to 2000 mV). It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of the claims.

摘要:
A valve actuator based on a conductive polymer gel is disclosed. A nonconductive housing is provided having two separate chambers separated by a porous frit. The conductive polymer is held in one chamber and an electrolyte solution, used as a source of charged ions, is held in the second chamber. The ends of the housing a sealed with a flexible elastomer. The polymer gel is further provide with electrodes with which to apply an electrical potential across the gel in order to initiate an oxidation reaction which in turn drives anions across the porous frit and into the polymer gel, swelling the volume of the gel and simultaneously contracting the volume of the electrolyte solution. Because the two end chambers are sealed the flexible elastomer expands or contracts with the chamber volume change. By manipulating the potential across the gel the motion of the elastomer can be controlled to act as a “gate” to open or close a fluid channel and thereby control flow through that channel.
