Abstract

During the last three decades intense studies have been carried out to understand the behavior of liquid crystals dispersed in various media. One of the most common outcomes is the polymer dispersed liquid crystals (PDLCs), in which liquid crystal droplets are dispersed in an appropriate polymer matrix. The investigation of PDLCs is of immense significance because of their strong potential for scientific and technological applications and basic understanding. The current article presents a comprehensive overview till date of the some important developments in this field. We begin with a brief discussion on the current scenario of dispersion studies in liquid crystals which is followed by the description of preparation, morphology, characterization and some important properties of PDLCs. Recent advancements such as PDLCs with conducting polymers, holographic PDLCs and influence of foreign elements on the properties of PDLCs are also covered. The remaining parts are concerned with the time dependent phenomenon and theoretical developments. A survey of some of their applications is also given. The article ends with a brief comment on future perspective and challenges.
