在前期的研究中我们对描述玻璃化转变的微观NLE理论进行了改进，从第一性原理的角度建立了可以描述具有链结构的体系的NLE理论，并把该理论扩展到了二维。本项目提出以此理论进展为基础结合积分方程理论、PRISM和Monte Carlo模拟等结构分析手段，对模型胶体链体系的玻璃化转变和动力学展开研究。主要探讨包括链结构（键长、链长、链柔韧性、"分子"构型）、维度和受限环境对玻璃化转变行为和性质的影响，比如玻璃化转变点、alpha弛豫时间曲线、"fragility"、各种特征尺寸和标度关系、弹性模量等的变化。该研究有助于从微观角度加深我们对玻璃化转变过程的认识，揭示大分子和小分子玻璃化转变行为的差异和产生机制，揭示维度和受限环境的影响机理。

In the former project, we developed a modified microscopic nonlinear Langevin equation (NLE) theory for deeply supercooled polymer melts and glasses, which treats chain connectivity and architecture from first principles. Also, we extended the theory from 3D to 2D. In this proposal, we plan to investigate the glassy dynamics and glass transition of model colloidal chains, by combining the modified NLE theory with the structural analysis methods such as integral equation theory, polymer reference interaction site model (PRISM) and Monte Carlo simulation, etc. The study will focus on the influence of "molecular structure" (including the type and characteristic length of bonds, chain length, rigidity and the architecture), dimensionality and confining environment on the glassy behaviors and properties, such as glass transition point, alpha relaxation time, "fragility", characteristic lengths and scaling relations, elastic modulus, etc. This study can enhance our knowledge on the glassy behaviors from microscopic scale, and reveal the differences in glassy behaviors between polymers and small molecules.
