Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the following embodiments and the accompanying drawings.
Referring to fig. 1 to 6, the method for preparing the nanoscale electro-jet 3D printing needle by using the swelling technology of the present invention includes the following steps:
(1) laser cutting of nano-scale electric jet 3D printing spray needle substrate
The specific operation steps are as follows:
(1a) taking a 5 multiplied by 5cm PMMA plastic substrate, and attaching a layer of preservative film on the substrate, aiming at ensuring that the surface layer material of the nano-scale electric jet 3D printing spray needle does not deteriorate in the laser cutting process;
(1b) placing the PMMA plastic substrate after film pasting on a laser cutting machine, and cutting under the conditions that the laser cutting current is 2.5-3 mA and the cutting speed is 10-15 mm/s; after cutting, a nanoscale electric jet 3D printing spray needle substrate 1 is formed, the shape of the nanoscale electric jet 3D printing spray needle substrate 1 is shown in figure 1, and the middle part of the nanoscale electric jet 3D printing spray needle substrate 1 after cutting forms a large circle and a small circle which are communicated with each other;
(1c) the burrs on the periphery of the cut nanoscale electric jet 3D printing spray needle substrate 1 are cleaned by a scraper (namely a wallpaper knife), so that unnecessary cracks are prevented from being generated in the subsequent operation, and the manufacturing quality of the nanoscale electric jet 3D printing spray needle is prevented from being influenced.
(2) Cleaning method for nanoscale electric jet 3D printing spray needle substrate
The specific operation steps are as follows:
(2a) ultrasonically cleaning the nanoscale electric jet 3D printing spray needle substrate 1 obtained in the step (1c), setting the water bath temperature to be 60-70 ℃, and the cleaning time to be 30-40 minutes;
(2b) taking out the nanoscale electro-jet 3D printing spray needle substrate 1, cleaning the nanoscale electro-jet 3D printing spray needle substrate 1 for 5 minutes by using deionized water, and drying the nanoscale electro-jet 3D printing spray needle substrate 1 by using nitrogen;
(2c) the nanoscale electric jet 3D printing spray needle substrate 1 is placed into an oven at the temperature of 65 ℃ to be baked for 24 hours, water in the nanoscale electric jet 3D printing spray needle substrate 1 is completely removed, the same water content of the PMMA material in the crack preparation process is guaranteed, and the same time reference is provided for swelling treatment.
(3) Nanoscale electric jet 3D printing spray needle substrate imaging
The specific operation steps are as follows:
(3a) manufacturing a silicon die with a swelling induction pattern 2 (see fig. 2), wherein the swelling induction pattern is a pattern with a rounded tip; the size of the silicon mould is larger than the size of the substrate of the nanoscale electric jet 3D printing spray needle. The height of the swelling induction graph 2 is 20 micrometers, and the height of the swelling induction graph 2 can ensure that cracks in the nano cracks manufactured by a swelling method can be propagated along a straight line;
(3b) aligning the silicon die with the swelling induction pattern 2 with the nanoscale electric jet 3D printing nozzle needle substrate under a microscope (see figure 3), wherein the inverted circle pattern on the swelling induction pattern 2 is tangent to the small circle cut by the laser in the step (1c), so that in the process of preparing the nanoscale electric jet 3D printing nozzle needle nanoscale cracks by a subsequent swelling method, the position of the inverted circle pattern cannot generate a stress set, cracks cannot be generated at the position, and the nanoscale cracks can be ensured to be generated only at the tip of the swelling induction pattern;
(3c) and under the conditions that the temperature is 110-115 ℃ and the pressure is 1-1.5 MPa, hot pressing is carried out on the nanoscale electric jet 3D printing spray needle substrate 1 by using a silicon die with a swelling induction graph 2, and the hot pressing time is 5-10 minutes. Under the hot pressing parameters, the deformation of the nanoscale electric jet 3D printing nozzle needle substrate 1 is small, and the depth of the swelling induction graph 2 after hot pressing is 20 micrometers.
(4) Preparation of nanoscale electric jet 3D printing spray needle substrate nanoscale cracks
The specific operation steps are as follows:
(4a) preparing an ethanol-deionized water solution, wherein the concentration of ethanol is 50-60%, and the ethanol solution with the concentration can reduce the denaturation tendency of the surface layer material of the nanoscale electric jet 3D printing spray needle substrate 1;
(4b) the nanoscale electric jet 3D printing spray needle substrate 1 is subjected to ultrasonic soaking in an ethanol solution, the ultrasonic treatment can accelerate crack generation, and the crack generation time can be shortened from 24 hours to 2 hours. The ultrasonic soaking water bath temperature is 70-80 ℃, the treatment time is 2 hours, and the ethanol solution is stirred every half an hour during soaking to prevent the nanometer crack size from being uneven due to uneven ethanol concentration. Since PMMA is a macromolecular material and ethanol is a micromolecular liquid, in the soaking process, ethanol molecules enter gaps of the PMMA material, so that the nanoscale electric jet 3D printing spray needle substrate 1 expands. Therefore, stress concentration is generated at the sharp end of the swelling induction graph 2 on the nano-scale electric jet 3D printing spray needle substrate 1, and a nano-scale linear crack (shown in figure 4) is generated in the stress concentration direction, namely the nano-spray needle 3.

(5a) taking out the nanoscale electric jet 3D printing spray needle substrate 1 obtained in the step (4b), and putting the nanoscale electric jet 3D printing spray needle substrate into deionized water for cleaning for 2 minutes;
(5b) placing the nanoscale electric jet 3D printing spray needle substrate 1 on a hot plate for drying, wherein the temperature is set to be 80-90 ℃, and the drying time is 4-6 hours;
(5c) fixing the periphery of the nanoscale electric jet 3D printing spray needle substrate 1 by using a clamp, and baking the substrate in an oven at the temperature of 105 ℃ for 20-25 minutes again to enable PMMA near the generated nano cracks to flow again, so that the nanoscale cracks on the nano spray needle 3 are further reduced to be below 100 nanometers, and a final spray needle nanoscale crack structure is formed.
(6) Nanoscale electric jet 3D printing spray needle package
The specific operation steps are as follows:
and (3) pasting a layer of PET single-sided adhesive on the upper surface and the lower surface of the substrate of the nanoscale electric jet 3D printing spray needle in the step (5c), cutting and punching the upper layer (the layer with the nanoscale cracks) of the nanoscale electric jet 3D printing spray needle (the punching position is shown in figure 5) to form a through hole 4, and removing the outer frame to form the final nanoscale electric jet 3D printing spray needle (shown in figure 6).
