“…Furthermore, use of nominal amount of monomer makes it a cheaper and environmental friendly technique [24][25][26]. Consequently, plasma polymerization polymer thin films have been extensively studied by large number of research groups around the world to realize various properties including structural, optical, electrical, and thermal features in search of their prospective scientific and technological [27][28][29][30][31][32][33][34].…”

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.

The properties of cyclohexane (CHex) and plasma polymerized cyclohexane (PPCHex) thin films are studied, and the results are compared with those obtained using a computing model (under the density functional theory framework). Quantum chemical calculations are performed to calculate their molecular electrostatic potential (MEP), highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) gaps, thermodynamic stability, chemical reactivity, and vibrational properties. The HOMO–LUMO energy gap sharply decreased in the case of the PPCHex thin film compared to that of CHex. Gibbs free energy shows a similar phenomenon where the enthalpy of PPCHex (formation) is almost six times higher than that of CHex. The computed FTIR spectra indicate good agreement with the experimental results. RMS roughness shows a smooth surface, and it is compared with the FESEM image. Moreover, the dielectric constant and electrical conductivity of the PPCHex thin films are also studied.
