Generally, the indium tin oxide (ITO) has been utilized as the transparent electrode in the polymer dispersed liquid crystals (PDLC) films display and in other opto-electronics devices. However, such ITO electrodes are high cost, which is because of the cost of indium metal and its processing onto glass substrate. In such circumstances, graphene could serve as a smart choice that can be employed as the transparent electrode on glass substrate which can be used in the PDLC films. Graphene provides low resistivity, high chemical stability, high optical transmittance, and mechanical strength that make graphene as an excellent transparent electrode. Consequently in the present timings, graphene and graphene oxide (GrO) based transparent electrodes demonstrate great potential for the fabrication of various smart flexible displays, and opto-electronics applications. The current review work presents some of the past and present ongoing developments in polymer dispersed liquid crystals (PDLC) fabricated with graphene and graphene oxide (GrO) electrodes as transparent electrodes.
