Abstract [en]

Polypyrrole is electromechanically active and actuates due to ion and solvent movements during redox switching, causing both reversible and irreversible swelling. The swelling of polymers is known to be highly dependent on the degree of cross-linking. Despite this, little research has been undertaken to date on the affect that cross-linking has on the actuation of conjugated polymers. It is likely that there exists a level of cross-linking, that results in optimum actuation performance. An understanding of this relationship, would allow actuators to be designed that are capable of greater movement, operating speeds and force generation. Here we present novel synthetic strategies aimed at altering the cross-linking density of electrosynthesised polypyrrole. The actuating performance of these materials has been assessed using new apparatus capable of making non-contact dynamic measurements. Our synthetic strategies, measurement setup and results will be presented.
