A fresh method for handling the content develop variety of applications is provided by the ability of three-dimensional (3D) printing technology. Anisotropic in nature, molybdenum disulfide (MoS2) is a multilayer transition metal dichalcogenide (TMD). Its exceptional physio-chemical characteristics include a high carrier mobility, tunable band gap, large surface-to-volume ratio, unique electrical characteristic, friction, catalytic, and optical qualities. However, LC/MoS2 composites are synthesized by microwave assisted method. LC/MoS2 nanosheets electrodeposited by silver (Ag) and gold (Au) to enhance the electrical conductivity of LC/MoS2 substrate. The characterization performed for the properties of this composites include electrochemical analysis, FESEM, Raman & UV- vis spectroscopies. As a result, current density of 2 A g−1, the nanocomposite exhibits an impressive capacitive response of capacitance 9.1 F g−1. Absorption peak lies in the visible region with band gap of 1.9 eV. In summary, we have effectively combined the optical and electrical properties of the different components to create a unique composite that served as a useful platform for the advancement in energy storage applications.
