Improved ordering and lubricating properties using graphene in lamellar liquid crystals of Triton X-100/CnmimNTf2/H2O

The addition of a small amount of graphene into LLCs can increase the order of the amphiphilic molecules and the thickness of the amphiphilic bilayer, which could effectively reduce the friction coefficient and enhance the loadbearing capacity.

EFFECT OF NANO- AND MICROPARTICLES OF IRON (III) OXIDE ON VISCOSITY OF LAMELLAR LIQUID CRYSTALS OF LECITHIN

The addition of low concentrations (0.001 – 0.1 wt. %) of iron (III) oxide nanoparticles with diameter of 10-20 nm was shown to result in the increase in a viscosity of lamellar liquid crystals in the systems of lecithin – water and lecithin – dodecane – water by 35-60% and 15-20%, respectively, whereas the addition of 1-5 µm microparticles does not affect the viscosity. An increase in a viscosity of the liquid crystals with the growth of the nanoparticles concentration from 0.001 to 0.1 wt. % is observed. It is assumed that the nanoparticles act as "bridges" between the bilayers of the lamellar liquid crystal.

Structural and rheological changes of lamellar liquid crystals as a result of compositional changes and added silica nanoparticles

By adding silica nanoparticles to lamellar liquid crystals, their flow and structure can be changed dramatically, indicating new ways to understand particle–membrane interactions.
