Conducting polymer actuator based on chemically deposited polypyrrole and polyurethane-based solid polymer electrolyte working in air

摘要: Conducting polymers (CPs), such as polypyrrole, polythiophene, and polyaniline, are unique in that they have switchable properties due to their two or more mechanically stable oxidation states. Thus, films coatings can be easily switched by the application of a small voltage current change volume during electrochemical redox processes. In particular, polypyrrole (PPy) has been studied most extensively because its high electrical conductivity good environmental stability under ambient conditions. this work, we new CP actuator, fully polymeric, assembled with PPy film electrodes solid polymer electrolyte (SPE), polyurethane/Mg(ClO4)2. Polyurethanes (PUs) were synthesized from 4,4'-diphenylmethane diisocyanate (MDI), 1,4-butanediol (1,4-BD) three types polyol: poly(ethylene glycol) (PEG), poly(propylene (PPG), PPG-block-PEG-block-PPG (PPG-co-PEG). The chemical polymerization immersion Py monomer aqueous solution oxidant is an adequate method prepare PU/PPy composite actuator. To find proper thickness coating layer for actuation, measured displacements actuators according layer. displacement all discussed connection SPE PPy. All results obtained work show feasibility electrochemomechanical devices based on being able air.
