AI Technical Summary

Problems solved by technology

However, people have not proposed a complete set of electro-deformation experimental equipment and testing methods. Due to the light weight and small size of carbon nanotube fibers, the axial shrinkage deformation produced when the electro-deformation test is energized in an electrolyte environment is only millimeters. The bubbles generated by liquid electrolysis when electrified, the influence of the surrounding environment during the experiment, and the buoyancy of the liquid on the fiber electrode have a great influence on the experimental measurement results.
