Characterization of Pyrrole Copolymer Soft Actuators Prepared by Electrochemical Polymerization Pyrrole and Diethyl 3,4-pyrroledicarboxylate

摘要

Polypyrrole (PPy) actuators, which expand and contract by doping and dedoping ions in an electrolyte solution, have been reported to have a large strain under a large stress. However, many of these actuators exhibited notable electrochemical creep (swelling) after repeated electrochemical actuations. Here, actuator films were prepared by electrochemical polymerization of pyrrole and diethyl 3,4-pyrroledicarboxylate with different mol ratios. The actuating strain of the film actuators prepared from a solution of pyrrole and diethyl 3,4-pyrroledicarboxylate with 97:3Â mol ratio showed significant reduction of the electrochemical creep with minimal reduction of the actuating strain.View full textDownload full textKeywords:Soft actuator, creep, polypyrrole, diethyl 3, 4-pyrroledicarboxylate, LiTFSIRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15421406.2012.701884
