Abstract

Abstract:

In order to improve the undergraduate education quality, Nankai University has organized undergraduate innovative research activities of "One Hundred Projects". College of Chemistry combines its own feature, and promotes the combination of theoretical teaching and scientific research practice in the form of "Scientific Research Feedback Teaching". College of Chemistry gives correct guidance to students as to joining scientific research innovation training and obtains satisfactory education outcome. Here we report the synthesis of two flame retardants and their application in flame retardant polycarbonate, which is one of the "One Hundred Projects" carried out in College of Chemistry in Nankai University. In the meantime, the specific implementation process and teaching effect of the "One Hundred Projects" are introduced.

Key words: Undergraduate innovative research activity, One Hundred Projects, "Scientific Research Feedback Teaching", Cyclotriphosphonitrile sulfonate, Polycarbonate, Flame retardant
