    The electromechanical properties of poly (3, 4-ethylenedioxythiophene)/poly (styrene sulfonate), (PEDOT/ PSS)-coated cellulose paper are investigated by varying the weight of PEDOT/PSS and frequencies of applied voltages. Through simple conformal coating, different weight of conductive PEDOT/PSS papers were fabricated and exhibited electromechanical actuation with stress generation controlled by low alternating applied voltage in ambient air. The dependence of electromechanical actuation on the weight of PEDOT/PSS and the frequency of the applied voltage are determined. The repeatability of the actuation is confirmed by generation of a stable stress more than 2000 times under ambient conditions. Furthermore, the PEDOT/PSS paper underwent intensive bending/unbending motion and showed a dependence on relative humidity. The present study suggests that PEDOT/PSS papers can be highly scalable for highperformance electromechanical devices in ambient air.

    This report describes the addition of deodorizing functionality to wool fibers by chemical modification for recycling used wool into a functional fiber material. Wool fibers were oxidized and succinylated and the effects of these treatments on ammonia sorption were evaluated. Oxidation significantly improved the ammonia sorption of wool fibers. The oxidized wool fibers also considerably sorbed methyl amine and dimethyl amine, though butyl amine and trimethyl amine were poorly sorbed. Ammonia sorbed rapidly with sulfuric acid groups but sorbed more slowly with carboxylic groups in oxidized and succinylated wool fibers. The sorbability of oxidized wool fibers after repeated sorption could be completely restored by washing with 0.5mM sulfuric acid.
