Embodiment Construction

[0012] The specific implementation manner of the patent of the present invention will be described in detail below in conjunction with the technical scheme and accompanying drawings.

[0013] 1. Structural engraving of nanoscale electrofluidic nozzles

[0014] (1) Use an engraving machine to cut the PVC heat-shrinkable sheet into a 5×8 cm PVC heat-shrinkable sheet base 1 (outline shape such as figure 1 shown in a). Ultrasonic cleaning of the PVC heat-shrink film substrate was performed with an alcohol-water mixed solution and dried with nitrogen gas. The alcohol concentration is 10% (cleaning with concentrated alcohol can prevent swelling and deformation of the PVC heat shrinkable sheet), the ultrasonic power is 50 watts, and the ultrasonic time is 10 minutes.

[0015] (2) Utilize self-made blade scratching equipment, such as figure 1 As shown in a, a liquid reservoir 2 with a diameter of 3 cm, an electrojet needle ink drainage channel 3 with a width of 2 mm, and an electro...

Abstract

The invention relates to manufacturing of nano-scale electric jet spray needles, in particular to a method for manufacturing a nano-scale electric jet spray needle based on a PVC heat shrinkage method. According to the method, a nano channel structure of the electric jet spray needle is manufactured by adopting the heat shrinkage characteristic of PVC, and the width of the manufactured nano channel can reach 280 nanometers. The whole method for manufacturing the nano-scale electric jet spray needle comprises three steps: 1, engraving a nano-scale electric jet spray needle structure; 2, manufacturing a nano-scale electric jet spray needle substrate; and 3, bonding the nano-scale electric jet spray needle substrate.

Description

technical field [0001] The invention relates to the preparation of nanoscale electric jet needles, in particular to a process for preparing nanoscale electric jet needles by using a PVC (polyvinyl chloride) thermal shrinkage method. Background technique [0002] Electrofluidic printing has the advantages of high printing resolution, nanometer-scale feature size, and strong adaptability to printing inks. Therefore, once this technology was proposed, it has attracted widespread attention from scholars in various fields. Currently, electro-fluidic printing has been able to print metal and polymer structures with feature sizes smaller than 100 nm. Electro-jet printing is based on the electro-hydraulic fluid effect, that is, the fluid in the electro-jet nozzle forms a semicircular liquid surface (meniscus) under the action of mechanical force, electric field force and other forces. When the electric field force breaks through the surface tension of the liquid, a fine jet (electr...
