本项目拟结合国际先进的高速差热分析技术和高效的分子模拟技术，通过理论模拟联系实验实际，系统地研究不同链长的环形高分子结晶的微观机理。我们将通过与线形高分子的平行比较，研究环形大分子及其链长对高分子结晶成核动力学和生长动力学的作用等关键科学问题，以深化我们对高分子结晶分子量效应的理解，进一步提高我们调控高分子结晶结构和性能的能力，同时广泛开展国内外学术合作，培养具有国际化视野的专业人才，以便其更好地服务于国民经济建设和社会发展的需要。

This project plans to combine the advanced fast-scan differential scanning calorimetry and high-efficient molecular simulations to systematically investigate the microscopic mechanisms of crystallization of cyclic polymers. By comparing to the parallel liner polymers, we will focus our attention on those key scientific problems in the field, such as the effects of cyclic polymer and the chain length on the kinetics of crystal nucleation and crystal growth. The target of this project is to deepen our understanding of the chain-length effects on polymer crystallization, in order to enhance our ability to adjust polymer crystalline structures and properties. In the meantime, we make a broad international collaboration to cultivate the world-wide vision of young talents, for their better service to the economic boosting and the society development in our country.
