The variations ITO concentration for observed properties of conductivity of polymer liquid crystal of cholesteryl acrylate-indium tin oxide

摘要

Liquid crystal polymer of Cholesteryl Aery late-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=0 group.The peak of the wavelength also shows the interaction of ITO with cholesteryl acrylate in PolyChoA-ITO.Characterization of PolyChoA-ITO using X Ray Diffraction(XRD)showed some peaks at 29 = 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 x 10-8 S/m.
