摘要:A polymer capillary electrophoresis chip is a novel kind of miniaturized device for biochemistry analysis. In this paper, a polymer micro hot embossing process is characterized by experiment and numerical simulation. a series of experiments were carried out with varied process conditions, including processing pressure, temperature and time. both the height and width of hot-embossed microchannel was investigated. Furthermore, a numerical simulation was developed to understand the mechanism of the hot-embossing process. Simulation results conform to related experiments. Based on these, a novel process of hot embossing is proposed, which lays the foundation for basic theories and techniques of structural design and manufactures of the polymer microchip.
