	1	Morphology-and ion size-induced actuation of carbon nanotube architectures显示文摘Future adaptive applications require lightweight and stiff materials with high active strain but low energy consumption.A suitable combination of these properties is offered by carbon nanotubebased actuators.Papers made of carbon nanotubes(CNTs)are charged within an electrolyte,which results in an electrical field forming a double-layer of ions at their surfaces and a deflection of the papers can be detected.Until now,there is no generally accepted theory for the actuation mechanism.This study focuses on the actuation mechanism of CNT papers,which represent architectures of randomly oriented CNTs.The samples are tested electrochemically in an in-plane set-up to detect the free strain.The elastic modulus of the CNT papers is analyzed in a tensile test facility.The influence of various ion sizes of water-based electrolytes is investigated.During the tests,four parameters that have a significant influence on the mechanical performance of CNT papers were identified:the test conditions,the electrical charging,the microstructure and the ion size.All of these influencing factors point to the mechanically weak inter-tube linking at which the actuation seems to take place.Quadratic voltage-strain correlation suggests a combination of electrostatic and volumetric effects as the possible reason for CNT paper actuation.
