Abstract

The invention relates to a microfluid chip and a spinning method thereof, particularly to a microfluid chip, width of a microfluid passageway being gradually reduced from an inlet to an outlet, and a spinning method thereof. The microfluid chip of the invention comprises a substrate and a diaphragm, wherein the diaphragm is provided with a groove, a surface of the diaphragm, where the groove is arranged in, is bonded with the substrate to form the microfluid passageway, the depth of the whole pathway is uniform, the width (b) of the microfluid passageway is gradually reduced from the inlet tothe outlet. By the spinning method of the microfluid chip provided by the present invention, spinning stock solution is injected into the inlet of the microfluid passageway of the microfluid chip andfinally flows out from the outlet of the microfluid passageway. The microfluid chip can perform dry spinning under atmosphere condition, conduct wet spinning in polymer coagulation bath, or conduct electrostatic spinning under high voltage electric field. The chip provided by the invention is simple in preparation and low in cost. Besides, drawing and cutting conditions needed by the solution in the chip can be regulated and controlled according to the requirement of spinning technology, thus, the chip has good application prospect.

Description

technical field

[0001] The invention belongs to the technical fields of microfluidics, textile fibers, material science and bionics, and relates to a microfluidic chip and a spinning method thereof, in particular to a microfluidic channel whose width gradually and continuously decreases from the inlet to the outlet. Microfluidic chip and spinning method thereof. Background technique

[0002] In recent years, the application of microfluidic chips in fiber formation is attracting increasing attention. Microfluidic technology can be spun under normal temperature and pressure conditions, which is very suitable for the processing of materials such as biomacromolecules. At present, microfluidic spinning technology has been well applied in the fields of instant spinning and electrospinning. In addition, the microfluidic spinning system may regulate the composition and structure of the spinning solution through the laminar flow and diffusion characteristics of the microfluid, so a...
