Electric field induction technology is a new technology for manufacturing micro-nano structures by controlling the polymer materials under high-intensity electrostatic fields. It has greater advantages in manufacturing efficiency, cost control, and process flexibility. However, domestic research is still in its infancy. Considerable challenges related to this new micro-nano manufacturing technology need to be addressed urgently. This project focuses on the key issues in the electric field induction process. Firstly, starting from theoretical research, the project would study the dynamic mechanism of electric field induction technology deeply and establish an effective multi-physics coupling theory system to explain the mechanism of complex process problems. Secondly, to solve the pain points of random disordered structures under a uniform electric field，a surface preparation technology with a quasi-ordered structure distribution based on a certain statistical law is proposed. Thirdly, the project proposes an electrode nano-roughening technology to solve the problem of cross-scale multi-level topography preparation. Based on the structured electrode, the electrode nano-roughening technology is introduced to induce the formation of multi-scale and multi-level complex topographic structures, and to achieve the controllable preparation of complex topographic structures. Finally, these specific functional structure films using electric field induction technology are coupled with quantum dots to form a structured quantum dot coating. It could solve the problem of poor dispersion of quantum dots and improve the scattering performance and light-color conversion efficiency, which is conducive to the realization of high-quality LED devices.
