Description

technical field [0001] The invention belongs to the field of intelligent polymer materials, and in particular relates to an MXene composite material-based electrochemical actuator, its preparation method and application. Background technique [0002] Animal muscles can perform complex movements such as stretching, bending, and twisting, and produce large deformations, and their structure and function have achieved incredible coordination. (Madden JDW et al. Artificial muscle technology: physical principles and naval prospects [J]. IEEE Journal of Oceanic Engineering: 2004, 29: 706-728.) For a long time, people want to imitate the movement of animal muscles, so people have always been In efforts to develop artificial muscles comparable to animal muscles, also known as actuators. Our most common actuators are internal combustion engines, electric motors and piezoelectric ceramics. Internal combustion engines are generally most efficient in continuous operation, making them u...
