BIFURCATION ANALYSIS OF A TWO-DIMENSIONAL BINARY MIXTURE OF HARD NEEDLES

Bifurcation analysis of a two-dimensional binary mixture of hard needles, which due to the second order of the transition character gives directly the density of the transitions, thus the phase diagram, has been performed for a complete set of the compositions and the needles lengths ratios within the framework of the Onsager approach. A limit of a mixture of needles and dot-like particles has been given. The possible changes in the phase diagrams caused by modification of the interaction strength of the different type particles are discussed. Prognosis of applications for the surfacial adsorption of the rod-type molecules like fibrinogen has been suggested. DOI:10.5506/APhysPolB.44.91
