Abstract

Another new computer simulation experiment in teaching course of "Experiments in Polymer Physics" was introduced. The morphology of two-dimensional self-avoiding walk chain and random walk chain was simulated based on improved four-site model. The corresponding scaling law was checked. It was found that the simulation results conform well to the theory of de Gennes.
