“…Figure 5 shows the FTIR spectra of the Ar ion beam treated PC/ABS samples at different times. The broad peaks at approximately 2 950 and 3 200–3 400 cm −1 were assigned to the stretching modes of different CH n group and OH vibrational mode,22, 23 respectively, and the peaks at 1 400–1 600 cm −1 were assigned to the vibrations due to the CC stretching mode 23. The peaks centered at 1 780 and 1 000 cm −1 were attributed to the CO and CO stretching modes, respectively.…”

This study examined the surface morphological evolution of polycarbonate and acrylonitrile butadiene styrene (PC/ABS) irradiated with an Ar ion beam using an ion beam system. PC was not affected by the Ar ion beam treatment at a lower ion beam treatment times but the ABS portion formed a foam-like nanostructure at the surface. On the other hand, both PC and ABS formed nanostructures with length of 100 to 120 nm and a mean diameter of %35 nm at longer beam treatment times. The Raman and FTIR spectra revealed polymer chain scissioning. Nanoindentation showed that the hardness and elastic modulus of the PC/ABS decreases from 0.22 to 0.18 GPa and from 3.39 to 2.98 GPa, respectively with increasing Ar ion beam treatment time due to the surface nano-structures formed by Ar ion beam.

“…In the last few decades, there has been growing interest in conductive polymers and composites due to an array of potential applications in biological and chemical sensors, separations, microelectronics circuit boards, biomedical, coatings, and optical displays [1][2][3][4][5]. The ability to prepare thin, flexible, transparent films is an asset in applications requiring nanostructuring and miniaturization [6]. Conductivity is a general property of metals, but some polymers in combination with organic charge moieties exhibit metallic behavior [7].…”

Recent advances in microelectronic and optoelectronic industries have spurred interest in the development of reticulate doped polymer films containing "metallic" charge transfer complexes. In this study, such reticulate doped polymer films were prepared by exposing solid solutions of bis(ethylenedioxy) tetrathiafulvalene (BEDO-TTF) in polycarbonate (PC) to iodine, forming conductive charge transfer complexes. The resulting films exhibited room temperature conductivities ranging from 6.33 to 90.4×10 −5 S ⋅ cm −1. The colored iodine complexes in the film were reduced by cyclic voltammetry yielding conductive, colorless, transparent films. We were intrigued to examine the dielectric properties of BEDO-TTF in solid solution in PC prior to formation of the charge transfer complex as no such studies appear in the literature. Dielectric analysis (DEA) was used to probe relaxations in neat PC and BEDO-TTF/PC. BEDO-TTF plasticized the PC and decreased the glass transition temperature. Two secondary relaxations appeared in PC films, whereas the transitions merged in the BEDO-TTF/PC film. DEA also evidenced conductivity relaxations above 180 ∘ C which are characterized via electric modulus formalism and revealed that BEDO-TTF increased AC conductivity in PC.

“…Seven of these substrates were simultaneously coated with 300 nm thick polycrystalline copper films, deposited under ultra high vacuum conditions via electron beam evaporation. After AFM surface characterization, deposition of 50 nm and 170 nm OBA thin films was carried out on different substrates by thermal evaporation of poly(bisphenol A carbonate) 12 (Sigma-Aldrich Co. LLC., CAS 25037-45-0).…”

Pattern transfer during deposition of oligomeric bisphenol A (OBA) on pre-structured Cu surfaces is investigated by means of a combined experimental-computational approach. Aiming for quantitative prediction of experiments, as characterized by atomic force microscopy (AFM), we explore the capabilities of stochastic rate equations to quantitatively account for the spatio-temporal evolution of surface topography. While surface diffusion and deposition noise constitute the main mechanisms, pattern transfer is affected by the inclusion of retardation in the interface potential, which appears to be necessary beyond a critical initial surface slope. In addition, routes for successful surface fixation by cross-linking are also demonstrated, which may pave the way for further technological use.
