ABSTRACT
The Cholesteryl Acrylate Polymer-ITO (CAP-ITO) composite in this study was successfully synthesized through a UV curing method with a variation in ITO nanoparticle dopant concentration. The results of the fourier-transform infrared spectroscopy characterization show a reduced peak hydroxyl and the carbonyl group in the spectrum shows an interaction between cholesteryl acrylate polymer and ITO. The results of testing the effect of ITO nanoparticle dopant on the CAP-ITO composite conductivity with an inductance, capacitance and resistance meter show that the addition of ITO as a dopant in a polymer cholesteryl acrylate can increase the conductivity of the composite even when compared to an ITO micrometer-sized dopant. A CAP-ITO composite with 10% w/w ITO concentration has the highest conductivity value that is equal to 5.70 × 10−7 S/m and reaches the threshold value at an ITO concentration of 20% w/w. These results are also supported by scanning electron microscope characterization which shows an equal morphological structure for the CAP-ITO composite with ITO 10% w/w.
