Abstract

Composite of cholesteryl acrylate-ITO nanoparticle was added Poly Ethilene Glycol (PEG) has been success synthesized. This research focus for study Properties of Crystallinity and Surface Morphology Of Composite Cholesteryl Acrylate-ITO nanoparticle was Added Poly Ethylene Glycol. XRD pattern of that product showed special peak at 2θ in 21o and confirmed nematic phasa. Therefore added PEG can be change the structures liquid crystal of cholesteryl acrylate. Prosen crystallinity from analysis by XRD that variations of PEG. Result this research PEG (0,001) is 8,14%; PEG(0,002) is 12,41%; PEG(0,003) is 14,85%; PEG (0,004) is 7,11; and PEG (0,005) is 8,66%. SEM image of composite cholesteryl acrylate-ITO nanoparticle that added PEG 0,003 showed picture rod and chain make crosslinked, that indications succecsfull photopolymerizations process. Much more PEG was added change directions of crystal the composite. That conditions making polymer to be micelle and can be effect to conductivity value because that polymer forming an aggregate.
