Impact of Dispersion of Nonmesogenic Materials in Liquid Crystals

Despite the great advances, the basic and applied understandings on the behavior of liquid crystals (LCs) continue to have a revolutionary technological impact and consistently pose new challenges. The basic understanding on the properties of  liquid crystals (LCs) is poor as compared to other materials. In applied aspects, the subject has achieved respectable positions. There are certain required qualities which LC based devices have to possess. In recent decades, for achieving these requirements the interest and emphasis on the science and technology of LC materials have shifted in two main directions: (i)To synthesize new materials possessing specific characteristics and properties that are appropriate for the applications, and (ii) to prepare a composite system by the dispersion (or doping) of nonmesogenic materials (NMMs) in the host LC and modify its properties so that the dispersed system becomes suitable for the applied applications.
