Evidence of nanodiamond-self-assembly in a liquid crystal, and the consequent impacts on the liquid crystal properties

Evidence of nanodiamond-self-assembly in a liquid crystal, and the consequent impacts on the liquid crystal properties

A small quantity of nanodiamonds (NDs) was dispersed in a nematic liquid crystal (LC), and the NDs were found to exhibit an anisotropic self-assembly along the nematic director. The anisotropic assembly of the NDs in the LC matrix was probed by measuring the dielectric anisotropy, Δε, of the LC+ND s...
