AC electrical conductivity (σac), dielectric constant (ɛ′), and dielectric loss tangent (tan δ) of plasma polymerized 1, 1, 3, 3‐tetramethoxy‐propane (PPTMP) thin films of thicknesses 100, 150, and 200 nm prepared by plasma polymerization technique using a capacitively coupled glow discharge reactor have been investigated in the frequency range of 30–106 Hz. It is observed that σac increases as frequency increases with a higher slope in the medium frequency (<105Hz) region in the PPTMP thin films of three thicknesses. These observations suggest that the conduction may be dominated by hopping of carriers between the localized states. The general trend of ɛ′ is to increase with increasing thickness, ɛ′ remains independent of frequency upto about 104Hz and then falls rapidly. The dependence of tanδ with frequency for PPTMP thin films of different thicknesses showed small relaxation peak at the very low frequencies (<102Hz) and then it decreases slightly with a broad minimum at 103 Hz and again increases. Cole–Cole plot reveals that Debye type of mechanism is operative in the experimental frequency range. POLYM. ENG. SCI., 58:1342–1345, 2018. © 2017 Society of Plastics Engineers

In this study, the results of dielectric spectroscopy of plasma polymerized poly(ethylene oxide) thin films are presented. The films were deposited by plasma-assisted physical vapour deposition at radio-frequency plasma discharge power of 5 W, and film thicknesses of 20, 100, and 250 nm. Dielectric measurements of the films were performed in the frequency range of 10−1–107 Hz and temperature was scanned between 173 and 353 K. The dielectric constant ([Formula: see text]) and dielectric loss ([Formula: see text]) of plasma polymerized poly(ethylene oxide) thin films were calculated by measuring capacitance (C) and dielectric loss factor (tanδ). It was observed that there were two relaxation mechanisms in the investigated frequency range. These were called α and β relaxations. These relaxations shift toward higher frequencies with increasing temperature. Moreover, α-relaxation starts to appear at different temperatures. This shows the difference between the polarizability abilities of samples at the same temperature and same frequencies. The reason for this behavior can be expressed by the dead layer concept, which is a result of good adhesion of the bottom layer of plasma polymer to the substrate. In light of these interpretations, with thinner samples it is possible to have structurally similar thin films like thin films deposited at high plasma power. A thinner film may support more transparency and these thinner films may be effective as coverage of optical devices, such as lenses, visors, etc.

Monomer 2-Furancarboxaldehyde (FCD) deposited via glow discharge technique onto glass substrates to produce plasma synthesized 2-Furancarboxaldehyde (PPFCD) thin films with different thicknesses. The various characteristics, such as the structural, optical, morphological and elemental properties of unaged (as deposited) as well as aged PPFCD thin films were studied using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) absorption spectroscopy, environmental scanning electron microscopy (ESEM), and energy dispersive X-ray spectroscopic (EDAX) methods. The XRD studies indicated the existence of small crystallite domains or amorphous nature of the PPFCD films. The ESEM micrographs exhibited the uniform, pinhole, and fracture free surface of PPFCD films together with no queerish morphological variations due to the aging effect. On the contrary, the EDAX and FTIR spectroscopic studies illustrated some structural rearrangement owing to the aging of PPFCD thin films. The UV-Vis studies revealed that the direct and indirect optical band gaps (E db and E ib ), and steepness parameter (σ) of the aged PPFCD films were significantly reduced from 3.43 to 3.20 eV, 2.18 to 1.53 eV, and 0.0546 to 0.0524 respectively while the Urbach energy (E u ) value was slightly enhanced from 0.48 to 0.50 eV. This indicated that the aging has remarkable effects on the optical properties of the PPFCD films.
