Generally, electric-conductivity materials such as metal, conductive polymers, and graphite are coated on the outside surface of the capillary tip followed by the application of an external high voltage on the tip to provide a sufficient electric field to generate electrospray in seathless interface. Thus, the fabrication of the electric-conductivity material on the surface of fused-silica is one of the main issues when using sheathless interfaces.

The main research tasks and results are as follows:(1) Through comparing the stress intensity factor of compact tension specimen calculated by finite element software with the theoretical value, the feasibility of calculating fracture parameters of crack tip in ABAQUS software was verified.(2) The relationship between the elastic modulus of the material and research scale was studied based on deriving the cohesive stress theory and other relevant theories.
