Spinodal Theory: A Common Rupturing Mechanism in Spinodal Dewetting and Surface Directed Phase Separation (Some Technological Aspects: Spatial Correlations and the Significance of Dipole-Quadrupole Interaction in Spinodal Dewetting)
Figure 7
Shows micrograph after 2000 Monte Carlo cycles (3D NVT-MC simulation of linear polymer). Circular holes are created in the polymer film caused by rupturing mechanism (i.e., spinodal dewetting). The polymer film is sandwitched between two hard walls. and sping constant of the film are taken as . Metropolis function has been used by performing a complete self avoiding random walk on the beads of the chains. FENE potential has been used for intrachain beads and Morse potentail for interaction between inter- and intrachain beads. The lower substrate has weak attractive potential to the beads. Peroidic boundary conditions are applied in X direction. Program has been developed by the author in f77.
