FABRICATION AND OPTICAL CHARACTERIZATION OF OLIVE OIL/AG THIN FILMS USING PLASMA POLYMERIZATION TECHNIQUE
To produce a polymeric material for use in electronic applications, traditional ‘wet’ methods of synthesis include chemical and electrochemical polymerization.. In addition, organic precursors that are unable to polymerize using conventional techniques have been found to undergo polymerization using this technique. Interest in the use of plasma polymerization originated due to its advantages, which include the ability to produce films that are of uniform thickness, pinhole-free, chemically inert and thermally stable The low cost of this fabrication technique is attributed to the associated low consumption of precursor material and the absence of any need for other chemicals and/or solvents, therefore making it ecologically friendly. The purpose of this work was to report the capability of converting Olive oil to a solid state thin film and study its optical properties. The FTIR spectrum indicated the presence of hydroxyl groups ,methylene (ــــCH2) group , C ـــO ester group,and so on for the rest of the chemical groups, the entire range of spectra looks very similar for the Olive oil.Major optical properties are determined from analysis of absorption and emission spectra to both of pure Olive oil and prepared doped Ag sample.Absorption spectrum showed of pure olive oil has a strong two peak around wavelength at 411 nm and 690 nm, with three other weak peaks appears at wavelength around 463 nm.All these peaks are disappearing and heavily overlap one another. from absorption spectrum of doped Ag, in which it could see only wide absorption peak at 358nm.
