Abstract
The invention provides a three-dimensional melting electrostatic printing method of a great-height micro-nano structure. The three-dimensional melting electrostatic printing method comprises the following steps: firstly, programming a program for controlling a platform to move on a computer; selecting a conducting medium solution for filling and a melting electrostatic printing material; filling into an injector of a melting electrostatic printing device provided with a plurality of spraying nozzles respectively and selecting melting electrostatic printing parameters; carrying out melting electrostatic printing to obtain a three-dimensional micro-nano structure with a pre-set thickness; filling the conducting medium solution into the three-dimensional micro-nano structure and gelling by utilizing temperature cross-linking and chemical cross-linking methods, so as to lift a melting electrostatic printing receiving platform; raising a distance between the melting electrostatic printing spraying nozzles and the receiving platform for the thickness of one colloid; repeating until the height of the three-dimensional micro-nano structure reaches a needed height, so as to obtain the great-height three-dimensional micro-nano structure through melting electrostatic printing. By adopting the three-dimensional melting electrostatic printing method of the great-height micro-nano structure, the disadvantage that the height of an electric field is attenuated along the rising of the height during a traditional melting electrostatic printing process is overcome; the three-dimensional melting electrostatic printing method can be widely applied to the fields including micro-nano devices, tissue engineering and the like.
