“…Conjugated polymers (CPs) are known as organic semiconductors with electronic properties and they have a wide application in electronic technology [1][2][3][4][5][6]. The polymers and especially CPs have been extensively used in electronic and optoelectronic device applications [7] such as organic field-effect transistors (OFETs), phototransistors, organic solar cells (OSCs), organic light-emitting diodes (OLEDs), sensors, lasers and electronic circuits due to simplified fabrication process of devices and their easy processing, unique processability from solution [8].…”

The optical properties of the solutions of the MDMO-PPV light-emitting polymer were investigated. The maximum mass extinction coefficient values of the solutions of the MDMO-PPV for 6.640 and 3.014 µM were found to be 20.874 and 42.009 L g −1 cm −1 , respectively. The absorption band edge values of the solutions of the MDMO-PPV shifted from 2.149 to 1.987 eV with increasing molarity. To obtain lower E g values (2.020, 2.057, 2.083, 2.088 and 2.103 eV, respectively) of the MDMO-PPV can be preferred xylene, toluene, chlorobenzene, chloroform and tetrahydrofuran solvents, respectively. The E g of the solution of the MDMO-PPV was decreased with molarities and solvents. The refractive index values of the MDMO-PPV were controlled with various solvents. The optical parameters such as single oscillator energy, dispersion energy, M −1 , M −3 moments, optical oscillator strengths, linear static refractive index, optical linear susceptibility, third-order nonlinear susceptibility and nonlinear refractive index were calculated using Wemple-DiDomenico equation. The highest contrast was obtained with xylene, while the lowest contrast was obtained with chlorobenzene. The MDMO-PPV can be used in the fabrication of the metal-semiconductor contacts due to low optical band gap and suitable optical parameters. Also, the surface morphology properties of the MDMO-PPV polymer film were investigated.

“…Since the initiation with thermo‐oxidative degradation with the formation of peroxide radicals occurs in the melt, the decrease in efficiency of this process for nanocomposites may mean that, on the one hand, diffusion of oxygen from the surface of the melt into the polymer volume is hindered, what is often observed for nanofilled polyolefins, but, on the other hand, may indicate a significant energy dissipation by Nafen particles. The latter assumption is confirmed by DMA analysis data mentioned above.…”

Nanofibers of Al 2 O 3 (commercial product Nafen TM ) with characteristic length of 100 nm and diameter of 10 nm were used to create new hybrid materials based on copolymer of ethylene and propylene. Nanocomposites were obtained by in situ catalytic copolymerization on the system rac-Et(2-MeInd) 2 ZrMe 2 /isobutylalumoxane. Formation of the nanocomposites with uniform distribution of Nafen nanoparticles in polymer matrix was confirmed by scanning and transmission electron microscopy. According to dynamic mechanical analysis data, introduction of the nanofiller in an amount of up to 3 wt % leads to an increase in glass transition temperature by 10 8C (E 00 ) and by 21 8C (tan d). The nanocomposites exhibit improved physico-mechanical properties (tensile strength and elongation at break). It is shown that the nanofiller significantly improves resistance of the nanocomposite to the thermo-oxidative and thermal degradation.

In this study, a new 5-phenyl-1,3,4-thiadiazole-containing vinyl monomer and its polymer were synthesized. The characterizations of the ligand, monomer and polymer were carried out using FTIR, UV-Vis, 1 H-NMR, elemental analysis and gel permeation chromatography techniques. The roughness average, root-mean-square roughness, surface skewness and surface kurtosis parameters of the poly(PTMPMA) film were found to be 1.98 nm, 2.84 nm, 1.529 and 5.777, respectively. Effects of the annealing temperature on optical properties of the poly(2-(((5-phenyl-1,3,4-thiadiazole-2-yl)imino)methyl)phenyl methacrylate) (PTMPMA) were investigated. The important optical parameters such as refractive index, optical band gap, angle of incidence, imaginary part of optical conductivity and real part of dielectric constants of the poly(PTMPMA) decrease and other important optical parameters such as excitation and dispersion energy, angle of refraction, real part of optical conductivity and imaginary part of dielectric constants of the poly(PTMPMA) increase with increasing annealing temperature. The absorption band edge values of the polymer films were found to be 2.34, 1.85 and 1.74 eV for 298, 523 and 643 K, respectively. The optical band gap values of the polymer films were found to be 3.314, 2.943 and 2.917 eV for 298, 523 and 643 K, respectively. The poly(PTMPMA) can be used as an active polymer layer in production of the electronic devices such as polymer diodes and metal-semiconductor contacts.Electronic supplementary material The online version of this article (
