Molecular Dynamic Simulation of Polymeric Materials at Cryogenic Temperature
Molecular dynamics simulation of polymeric material was carried out in order to obtain the selection standard for the polymers having better characteristics at cryogenic temperatures. Several hundreds of spherical particles which modeled CH2 group were chained linearly and the equations of motion of each sphere was solved. The four types of forces originated from van der Waals, valence bond, valence angle and dihedral angle were considered. the effects of deformation and irradiation was studied. It will discussed that how the microscopic movement of molecules influence on macroscopic properties at cryogenic properties.
