3D打印全固态柔性离子凝胶的性能及应用
Performance and Application of 3D Printing Solid-state Flexible Ionogel
摘要
Abstract
In order to resolve the instability of hydrogel-based wearable devices caused by dehydration,solid-state flexible ionogels were prepared from acrylic acid(AAc),choline chloride(ChCl)and montmorillonite(Mt).The mechanical properties of the ionogels were measured by using the universal testing machine,and the electrical conductivity was characterized by using the electrochemical workstation.At the same time,the electromechanical responses under different motion behaviors were monitored by using a digital multimeter.Finally,ionogel sensors with different complex structures were fabricated by using DLP-3D printer.The results showed that the synthesized ionogel had high fracture strength(1-5.7 MPa),high tensile(fracture strain~350%),and high ionic conductivity(6.38-15.91 mS/m).Ionogels demonstrated excellent elasticity,and as a flexible sensor it could reliably and accurately identify electromechanical signals generated by different strains and different loading speeds.The ionogels also showed good long-term stability.After being stored at a high temperature of 75℃for 100 h,the ionogels still had the same mechanical properties,conductivity and electromechanical response as the original specimen.Moreover,the porous structure of ionogels printed by using DLP showed a high rate of separation and could monitor different motion states of the human.关键词
