First of all, as a derivative major of chemistry and chemical engineering, polymer majors require exposure to various toxic and harmful solvents in most directions. Therefore, there is no doubt that it is harmful to the body. However, there are differences in the degree of toxicity in different professional directions. Generally speaking, the synthetic direction is more toxic, followed by biomaterials and nanomaterials, and engineering plastic modification should be less toxic. Secondly, it is dangerous to do experiments, please be cautious to apply for the handicapped party. Third, if you want to study a Ph.D. or take the path of scientific research, it is better to work on biomaterials or nanomaterials. It is better to publish articles. Although my grades are not bad, I get a scholarship every year for my undergraduates. After I graduated, I have been doing plastic modification and publishing Chinese journals, so the scholarship is hopeless. Fourth, in terms of employment, there are big differences between men and women. Boys are basically stress-free to find a job, and girls are really hard.
