Abstract
The 21st century is an era of Nanotechnology which is combined with technology, science and material. And material is manufactured into the products via the process technology. It is important to understand the physical properties of the material in order to benefit form the characteristic of polymer. Adding polymer into solvent to form solution among the process of technology is general now, and further make into the membrane. It is very important for prospect of application and has great market and value under nano scales. In the work, results of different tacticity for polypropylene are present via molecular dynamics simulations, based on understanding the differences of three-dimensional chemical properties that the pendent (C-CH3) methyl groups for polypropylene arrange on the space differently. Such as the conformation of chains for polypropylene are analyzed and discussed. Effects of the concentration of solutions and chain length are also investigated. Polypropylene is a vinyl polymer with a wide variety of applications that there is a wonderful physical property because of pendent (C-CH3) methyl groups arranged on the space differently. This research will make comparisons with paper first, in order to ensure the validity of programs for the systems and materials. Then different structures of polypropylene mixing with non-polarity solvent are compared via the radial distribution functions, end to end distance, and radius of gyration, etc.
