Electro Optical Properties of MBBA Liquid Crystal Doped with Carbon Nanotubes

Abstract

In this study, the effect of carbon nanotubes (CNTs) at various concentrations (0.05, 0.06, 0.08, and 0.1 wt.%) on the electro optical properties of liquid crystal (LC) has been studied. Results show that the threshold voltage, frequency response, rise time and response time of pure LC optical switch decreased with the concentration of CNTs. LC doped with 0.08 wt.% of CNTs revealed the most significant enhancement, resulting in a response time reduction of about 94%, confirmed that the doped LC is the best for the optical switch applications.
