Embodiment 1

[0034] A method for the controllable preparation of fiber arrays based on a superamphiphobic surface, comprising the following steps:

[0035] Step 1. Take a 30mm×30mm×0.17mm glass sheet and move it slowly and evenly in the burning candle flame for 1min to collect the carbon nanoparticles in the candle flame and deposit them evenly on the glass sheet. A 30mm×30mm×0.17mm glass piece is placed in a desiccator with a bottom diameter of 240mm. Take 4mL tetraethyl orthosilicate and 4mL ammonia water and place them in two separate beakers and place the beakers in the desiccator. Vacuumize the desiccator to -0.08MPa and maintain the sealed state for 24 hours. Tetraethyl orthosilicate and ammonia water in the desiccator deposit silica nanoparticles on the carbon nanoparticles on the surface of the glass sheet by the stober method; take out the glass sheet and place it in a horse In a Furnace, heat up to 600°C to remove carbon particles on the glass sheet, take out the glass sheet, and...

Abstract

The invention discloses a fiber array controllable preparation method based on a super-bi-hydrophobic surface. The method includes the following steps that a, the super-bi-hydrophobic surface is prepared on one face of a 30 mm*30 mm*0.17 mm glass sheet, and a super-bi-hydrophobic surface glass sheet is obtained; b, a polymer and a solvent are fully stirred and mixed according to different mass ratios, and a polymer spinning solution is prepared; c, the super-bi-hydrophobic surface glass sheet is put on a clamp of a stepping device of a microfluid spinning machine, and the glass sheet rotates at the speed of 50 r/min-500 r/min; d, an injector is used for extracting the prepared polymer spinning solution, the polymer spinning solution is extruded to the upper face of the super-bi-hydrophobicsurface glass sheet at the speed of 0.05 mL/min-0.5 mL/min through a microflow pump of the microfluid spinning machine, the stepping device of the microfluid spinning machine transversely moves at the speed of 1 mm/s-10 mm/s, the polymer spinning solution is collected from the super-bi-hydrophobic surface glass sheet, and regularly-arranged polymer fibers are obtained. According to the method forcarrying out microfluid spinning on the super-bi-hydrophobic surface to prepare a fiber array, the obtained fiber array is higher in regularity, and the preparation method is simpler and easier to carry out.

Description

technical field [0001] The invention belongs to the technical field of preparation of polymer fiber arrays, and in particular relates to a controllable preparation method of fiber arrays based on a superamphiphobic surface. Background technique [0002] Due to its material composition, array structure, and application characteristics, the polymer fiber array can be designed and prepared by different preparation technologies, and has the characteristics of controllability, easy transplantation, and doping. It is widely used in biomedical engineering, chemical industry, electrochemistry and Flexible electronics and other fields have extremely broad application prospects. At present, the design methods of polymer fiber arrays are mainly based on electrospinning, but it is difficult to obtain regularly arranged fiber arrays by ordinary electrospinning. In recent years, some new fiber array spinning preparation methods have been developed based on electrospinning technology, mai...
