Strengthening and Functionalization of Polymer by Controlling the Morphology, Strength and Boundary Layer of Microscopic Filler

提出了一种基于非仿射分子链网络模型的粘弹性本构方程。将所得到的本构方程和单胞模型沿着与均匀化方法相结合，对橡胶/聚合物微粒填充体系的变形行为进行了研究。通过一系列的模拟研究，阐明了在静态和动态加载过程中，通过适当的颗粒体积分数、颗粒尺寸和分布形态、颗粒与聚合物之间的边界层以及聚合物的结晶度来改善聚合物的力学性能。

A new viscoelastic constitutive equation based on nonaffine molecular chain network model was proposed. The obtained constitutive equation and unit cell model along with the homogenization method was fully employed to evaluate the deformation behavior of microparticle-filled rubber/polymer. A series of simulations clarified suitable combination of volume fraction, size and distribution morphology of particles and boundary layer between polymer and particles, and crystallity of polymer to improve themechanical characteristics under static and dynamic loading processes.
