INTERRELATIONS BETWEEN TRIBOLOGICAL AND RHEOLOGICAL CHARACTERISTICS OF AQUEOUS SOLUTIONS OF DISCOTIC MESOGENES

摘要

A number of macroheterocyclic dyes have been studied as tribological additives, including the compounds of the class of phthalocyanine derivatives (aqueous solutions). The results of the tests were interpreted relating to the data on surface tension and viscosity of lubricants. A conclusion is made that the tribological effectiveness of mesogenous additives of the phthalocyanine origin is determined by the presence of the discotic molecule.
