  • Abstract Organic materials are widely used as optoelectronic components, light
    emitting devices, thin film transistor (TFT), and sensor. Organic
    optoelectronic components have characteristics of thin film and low
    temperature process, it is easy utilized to varied substrates than conventional
    inorganic process. Using plasma polymerization process has such attracting
    properties as stability, insulating property and good transmission in the
    visible region to apply optical films (coatings), microelectronic devices and
    so on. Perfluoromethylcyclohexane (PFMCH) film and Benzene film can be
    deposited on substrates by low temperature plasma polymerization. The
    PD-PFMCH film as low refractive index (1.38±0.03) layer and PD-Benzene
    film as high refractive index (1.65±0.05) layer periodic stacking
    layer-by-layer for six layers. The relationship among the operational
    parameters of plasma deposition and the properties of deposited single or
    multilayer film were investigated in this study. Plasma deposited
    Hexamethyldisilazane (HMDSZ) film contains peroxide which can
    subsequently conduct graft polymerization through free radicals. Grafting
    the hydrophilic p-styrenesulfonic acid sodium salt (NaSS) or acrylamide
    (AAm) onto PD-HMDSZ film surface by UV-induced grafted was feasible.NaSS monomer via UV-induced grafting produce refractive index as 1.83±
    0.327 and grafting AAm monomer produce refractive index as 1.55±0.216.
    Results show the water contact angle of the PD-PFMCH film is
    hydrophobicity over 100 degree and the PD-Benzene film is 30 degree, the
    deposition rate of the PD-PFMCH films is 30.4±4.3 nm/min. at 0.4 W/P, the
    PD-Benzene film is 32.2±3.8 nm/min. at 0.6 W/P and the PD-HMDSZ films
    is 17.3±2.8 nm/min. at 0.8 W/P, the morphologies observation by scanning
    electron microscope (SEM) and atomic force microscope (AFM) show the
    roughness of surface lower than 2 nm, UV/Vis spectrophotometer analysis
    show the optical property and calculate band gap of the PD-PFMCH films is
    from 3.46 to 3.80, the PD-Benzene film is from 3.46 to 3.62 and
    PD-multilayer film is from 3.92 to 3.98, chemical component analysis of
    micro Fourier transform infrared spectroscopy (micro-FTIR) and electron
    spectroscopy for chemical analysis (ESCA).
