Abstract :
The effect of polymerization time on ionic liquid (IL) nanocoating onto polypyrrole (PPy) adsorbed cellulose and its influence on electrical and electromechanical properties were investigated. Cellulose-PPy-IL (CPIL) nanocomposites were fabricated by polymerization-induced adsorption process followed by subsequent activation in 1-butyl-3-methyimidazolium chloride IL solution. Fourier transform-IR spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy analysis showed successful preparation of the CPIL nanocomposites. Results revealed that CPIL nanocomposites can be utilized to develop a highly durable biomimetic actuators working in ambient condition. Preparation, characterization, and performance test of the actuators are explained.
