Problems solved by technology

For example, when preparing conductive silk, it is often treated by doping conductive fillers such as carbon nanotubes. Although the mechanical strength has increased, due to the stress concentration effect, the elasticity of the silk will be greatly reduced, which often has a negative impact on the performance of the silk.
