Problems solved by technology

However, in the final stage of the inversion method, the patterned polymer needs to be carefully peeled off from the photoresist mold. There are many microstructures on the patterned polymer, which are easily damaged during the stripping process. The requirements for equipment and environment are very high, and the quality is difficult to control. control

Abstract

The invention discloses a method for preparing a patterned polymer, and relates to the technical field of micro-fluidic chips. The method comprises the following steps: S1, spraying a photoresist, S2,transferring a pattern, S3, developing with a developing solution, S4, coating a polymer, S5, dissolving the polymer, and S6, demolding the photoresist. According to the invention, the separation between the polymer and the patterned photoresist is converted into dissolution separation from traditional stripping, the separation process of the polymer and the patterned photoresist is gentler, thepatterned polymer structure is not easy to damage, the production quality is higher, the requirements on the operation difficulty, the equipment precision and the operation environment are lower, andthe production quality is more stable and the production is more efficient.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a method for preparing patterned polymers. Background technique [0002] Microfluidic chip technology integrates the basic operation units such as sample preparation, reaction, separation, and detection in the process of biological, chemical, and medical analysis into a micron-scale chip to automatically complete the entire analysis process. Due to its great potential in the fields of biology, chemistry, and medicine, it has developed into a new research field interdisciplinary in biology, chemistry, medicine, fluid, electronics, materials, and machinery. Currently, microfluidic chips can be fabricated using materials such as glass, polymers, hydrogels, paper, etc., but the most common materials are polymers. Among them, silicones such as polydimethylsiloxane (PDMS) are widely used in polymers, and other types of polymers such as polymethyl methacrylate and polycarbon...
