摘要
Developing moisture-sensitive artificial muscles from industrialized natural fibers with large abundance is highly desired for smart textiles that can respond to humidity or temperature change.However,currently most of fiber artificial muscles are based on non-common industrial textile materials or of a small portion of global textile fiber market.In this paper,we developed moisture-sensitive torsional artificial muscles and textiles based on cotton yarns.It was prepared by twisting the cotton yarn followed by folding in the middle point to form a self-balanced structure.The cotton yarn muscle showed a torsional stroke of 42.55°/mm and a rotational speed of 720 rpm upon exposure to water moisture.Good reversibility and retention of stroke during cyclic exposure and removal of water moisture were obtained.A moisturesensitive smart window that can close when it rains was demonstrated based on the torsional cotton yarn muscles.This twist-based technique combining natural textile fibers provides a new insight for construction of smart textile materials.
