Embodiment 1
[0025] (1) Take the cone-shaped fiber with anisotropic microstructure with a length of 1 cm and use acetone, alcohol and water to sonicate for 5 minutes respectively, clean it, and dry it at room temperature; figure 2 As shown, each tapered fiber with anisotropic microstructure has a tapered structure with a gradually changing diameter, and the surface is covered with a gradient arrangement of oriented structures,
[0026] Such as figure 2 As shown, the specific structure of the cone-shaped fiber with anisotropic microstructure is: the main body of the fiber is a cone-shaped material with polysaccharide and protein structures; the diameter of this cone-shaped material changes from 0 to 150 microns, forming a tapered cone Shaped structure; the surface of the cone-shaped structure is covered with a layer of oriented structure with a height of 100 nanometers. The role of the oriented "scale-like" structure is: when the liquid is on the surface of this "scale-like" structure, t...
Embodiment 2
[0031] (1) Use acetone, alcohol and water to sonicate 5 cm-long tapered fibers with anisotropic microstructure for 15 minutes, clean them, and dry them at room temperature;
[0032] (2) Select 2 tapered fibers with anisotropic microstructure obtained in step (1) and arrange them closely, and bond the thick ends of the fibers to a glass sheet, and connect the glass sheet to a liquid storage pool composed of rubber tubes , to prepare the printing tool;
[0033](3) Rhodamine B is added with water to make a solution with a mass percentage of 1%, and polyvinyl alcohol (PVA) is added to the above solution to make a 0.1% PVA solution with a mass ratio to make a functional molecule solution and inject the stock solution pool;
[0034] (4) Connect the printing tool obtained in step (1) to the three-dimensional mobile platform, such as figure 1 As shown, close to a smooth glass substrate at an angle of 45° to the plane until it touches, and move rapidly at a speed of 10mm / s to produce...
Embodiment 3
[0036] (1) Use acetone, alcohol, and water to ultrasonicate 5 minutes of tapered fibers with anisotropic microstructure with a length of 2 cm, clean them, and dry them at room temperature;
[0037] (2) Choose two tapered fibers with anisotropic microstructure obtained in step (1) and arrange them closely, and bond the thick ends of the fibers to a glass sheet, and connect the glass sheet to a liquid storage pool composed of rubber tubes , to prepare the printing tool;
[0038] (3) Silver nanoparticles are added with water to be made into a nanoparticle solution of 1% by mass percentage, and polyvinyl alcohol (PVA) is added to the above solution to be made into a 0.1% PVA solution by mass ratio to make a functional molecular solution, inject reservoir;
[0039] (4) Connect the printing tool obtained in step (1) to the three-dimensional mobile stage, and approach the smooth glass substrate at an angle of 45° to the plane until it contacts, and move rapidly at a speed of 10 mm / s...
