英文摘要: This project aims to establish a method capable of simulating both the mesostructures and mechanical properties of polymer composites such as polymer blends and polymer-matrix nanocomposites. The expected outcome will be a combination of Monte Carlo method, whose basic theories are the bond fluctuation model and vacancy diffusion algorithm, and the lattice spring model, which is specializing in the analysis of the mechanical properties of heterogeneous materials. By importing viscoelasticity component into the lattice spring network, the processing history of a certain material can be traced and compared with the experimental results afterwards. Overall, the establishment of the simulating method is particularly promising and instructive in molecular design of composite materials.
