Primitive path analysis of linear polymer embedded in post array

Abstract

We present an extensive set of simulation results for the relaxation processes of linear polymer chains embedded in post arrays using Monte Carlo algorithm. The data allow us to explore the crossover of chain dynamics from single-chain regime to entangled regime. Using primitive path analysis, the statistical information of the system, including the average value and the fluctuation of the length of primitive path, is also obtained. We have performed a clear test on Doi’s theory on contour length fluctuation and we find excellent agreement for Doi’s theory in entangled regime.
