Effect of Polymer Matrix Density on Molecular Segregation and Orientational Ordering by a Hybrid Computer Simulation
Physics and Astronomy
A hybrid computer simulation is used to study the effect of heterogeneous matrix density (p(b)) on the segregation and orientation of short-chain molecules, i.e., dimer, trimer, etc., a model for polymer dispersed liquid crystal (PDLC) in an external field. Size of molecular aggregates is found to increase with the matrix density, a polymerization-induced segregation consistent with the recent experimental observation (Boots and coworkers, Macromolecules 29 (1996) 7690; Liq. Cryst. 22 (1997) 145,255.). For low molecular weight liquid, the orientational ordering decreases monotonically with p(b), while the orientation in a higher weight liquid depends nonmonotonically on P-b (C) 2000 Elsevier Science B.V.
