摘要
The phase behavior of mixtures of linear flexible polymers and V-shaped liquid crystals (LCs) is inspected using a combination of the Flory-Huggins (FH) theory of polymer solutions and the Landau-de Gennes theory of nematic ordering. The influence of the architecture of V-shaped molecules on the system's phase diagrams is examined.
