technical field [0001] The invention relates to the technical field of microfluidic synthetic material equipment, in particular to a uniformly mixed microfluidic reaction synthetic material device. Background technique [0002] Microfluidics is the science and technology involved in systems that use micropipes (tens to hundreds of microns in size) to process or manipulate tiny fluids. It is a discipline involving chemistry, fluid physics, microelectronics, new materials, biological Emerging interdisciplinary science and biomedical engineering. Because of the characteristics of miniaturization and integration, microfluidic devices are usually called microfluidic chips, also known as lab on a chip (Lab on a Chip) and micro-Total Analytical System (micro-Total Analytical System). [0003] At the same time, microfluidic technology can also be used to synthesize materials, especially for nanomaterials, the use of microfluidic technology can effectively ensure the synthesis accur...

AI Technical Summary

Problems solved by technology

When the current microfluidic synthetic materials are used, because the diameter of the microfluidic microchannel is very small, the fluidity of the liquid in the microfluidic channel is generally in a laminar flow state, which leads to poor mixing uniformity and it is difficult to achieve uniformity. Moreover, if the temperature control is not good, the accuracy of the mixing is also difficult to meet, especially the size error of the liquid and the flow channel are related to the temperature

In addition, for ordinary microfluidic devices, it is difficult to prepare mixtures with different ratios, and it is difficult to study the ratio of synthetic materials
