An evolving network model in polymer melts with community structures

摘要

In order to describe the entangled network structure in polymer melts visually, we propose an evolving network model with community structure. This network model grows according to the innercommunity and inter-community preferential mechanisms of both community sizes and node degrees. Numerical simulation results indicate that the cumulative distribution of community size and node degree distribution follow power-law distributions P(S ≥ s)～s~(-υ) and P(k)～k~(-γ) respectively, with the exponents of υ ≥ 1 and γ ∈ [0,+∞).
