| Outline of Final Research Achievements |
Polymeric materials are widely used in modern industry. However, a quantitative prediction of polymeric properties is still a challenge because the physical picture behind it is quite complicated. A combinational use of a molecular dynamics (MD) and Langevin dynamics (LD) is a promising approach to solve this problem. MD can quantitatively provide polymeric properties of short time phenomena, whereas LD can qualitatively provide these of long time phenomena. In this work, we attempted to quantitatively estimate polymeric properties of long time phenomena by interconnection of MD and LD. In order to achieve it, long time MD simulations (micro second order) were needed for macromolecular systems. Therefore a novel intermolecular interaction calculation method was developed for acceleration of MD simulations.
