【 摘 要 】
Liquid crystal polymer of Cholesteryl Acrylate-Indium Tin Oxide (PolyChoA-ITO) in this study has been successfully synthesized by UV curing method, which variations of ITO concentrations i.e. 0, 10, 20, 30, 40, and 50% w/w. This research using ITO as a doping on a cholesteryl acrylate monomer and subsequently polymerized. Characterization of PolyChoA-ITO using FTIR, that resulted a peak at 1600-1750 cm-1 that identifies the stretching vibration of the C=O group. The peak of the wavelength also shows the interaction of ITO with cholesteryl acrylate in PolyCho A-ITO. Characterization of PolyChoA-ITO using X Ray Diffraction (XRD) showed some peaks at 2θ = 7,53; 15,27; 8,10; and 30,40; which is the typical peak of ITO and the typical peak of cholesteryl acrylate. SEM image of PolyChoA-ITO shows that ITO is agglomerated on the surface of cholesteryl acrylate polymer that uniform. Conductivity properties of PolyChoA-ITO shows that the higher concentration of ITO is added the greater the conductivity value. The maximum conductivity value of PolyChoA-ITO at 10% ITO concentration is 50.352 × 10-8 S/m.
