摘要: We study the nematic–isotropic transition in model colloidal systems composed of platelets various shapes using grand canonical simulations. This is relevance for recently synthesized hard platelet systems, since such are found to be not circular but irregular hexagons, and so cannot described by simulation data currently available. show that coexistence densities scale with an effective volume related isotropic orientation-averaged excluded a pair platelets. can obtained from perimeter face particles easily calculated both regular particle shapes.
