项目摘要
This proposal, "US-Bulgaria Cooperative Research on Computer Simulations of Polydisperse Polymer Systems," will be carried out by Dr. David P. Landau, University of Georgia and Dr. Andrey I. Milchev, University of Sofia. It envisages an ambitious program of research, designed to shed light on the complex cooperative behavior of a polydisperse system of semiflexible polymer chains in the presence of an adsorbing surface. Since the thermodynamic properties of such a system are so far largely unknown, the researchers believe that in a collaboration of three years they can produce a sufficient number of results in order to get a complete picture of the phenomena in question. The program of research should focus on: (1) Determination of the order of the disorientation phase transition in 2D; (2) Establishment of a total phase diagram in the multiparameter space of the energy interactions, temperature and density; (3) Investigation of adsorption isotherms and the adsorption-description phase transition for polydisperse systems with different average chain length and stiffness; (4) Study of the density profile and the structure of the polymer solution as a function of the distance from the adsorbing surface; (5) Investigation of the impact of impurities on the thermodynamic and structural properties of the system. The problem is of major practical importance since it has broad implications in lubrication, adhesion, surface protection, etc. technology. Polymers, adsorbed at the surface of colloid particles, lead to (steric) stabilization of the colloid suspension which is important for dyes production. This research in materials theory fulfills the program objective of advancing science by enabling leading experts in the United States and Bulgaria to combine complementary talents and pool research resources in areas of strong mutual interest and competence.
这项名为“美国-保加利亚多分散聚合物系统计算机模拟合作研究”的提案将由佐治亚大学的 David P. Landau 博士和索非亚大学的 Andrey I. Milchev 博士进行。 它设想了一个雄心勃勃的研究计划,旨在揭示半柔性聚合物链多分散系统在吸附表面存在下的复杂合作行为。 由于迄今为止这种系统的热力学性质在很大程度上是未知的,研究人员相信,通过三年的合作,他们可以产生足够数量的结果,以便全面了解所讨论的现象。 研究计划应重点关注:(1)二维定向障碍相变级数的确定; (2) 建立能量相互作用、温度和密度多参数空间的全相图; (3) 研究不同平均链长和刚度的多分散体系的吸附等温线和吸附-描述相变; (4) 研究聚合物溶液的密度分布和结构作为距吸附表面距离的函数; (5)研究杂质对体系热力学和结构性质的影响。 该问题具有重大的实际意义,因为它对润滑、粘附、表面保护等技术具有广泛的影响。 吸附在胶体颗粒表面的聚合物可实现胶体悬浮液的(空间)稳定,这对于染料生产非常重要。 这项材料理论研究使美国和保加利亚的领先专家能够在共同感兴趣和能力强的领域结合互补人才并汇集研究资源,从而实现了推进科学发展的计划目标。
