“…where M A is the molecular mass of the material, which is the average 23,000 g/mol [32] of the light-emitting polymer MDMO-PPV. The maximum mass extinction coefficient (α mass−max ) values at ε max values (4.801 9 10 5 and 9.662 9 10 5 L mol −1 cm −1 , respectively) of the solutions of the MDMO-PPV polymer for 6.640 and 3.014 µM were found to be 20.874 and 42.009 L g −1 cm −1 , respectively.…”

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.

“…The nanomechanics of polymer materials has become increasingly significant for advanced technological applications including the field of optics, electricity, acoustics, mechanics, and biomedicine [1]. In order to determine the mechanics of polymer materials, research using micro samples is a large challenge, especially in some special environments or experiments [2][3][4][5][6][7]. In 2016, Qi et al presented a novel approach to achieve microscale stimuli-responsive deformation of Janus structures for polymer actuators [6].…”

A fast and highly sensitive polymer nano-mechanical thermal analysis method for determining the melting temperature (Tm) of polymer microwires was proposed. In this method, a small-size, low-cost quartz tuning fork was used as a piezoelectric transducer to analyze the thermodynamics of polymer microwires at the nanogram level without changing its own properties. Due to the thin wire sample, which has a length of 1.2 mm and a diameter of ~5 µm, which is bridged across the prongs of the tuning fork, the nanogram-level sample greatly reduces the thermal equilibrium time for the measurement, resulting in a fast analysis for the melting temperature of the polymer sample. Compared with the traditional method, the analysis method based on the quartz enhanced conductivity spectrum (QECS) does not require annealing before measurement, which is an essential process for conventional thermal analysis to reduce the hardness, refine the grain, and eliminate the residual stress. In this work, the melting temperatures of three of the most commonly used polymers, namely polymers polymethyl methacrylate, high-density polyethylene, and disproportionated rosin, were obtained under the temperature from room temperature to >180 ℃, proving the QECS method to be a useful tool for nano-mechanical thermal analysis.
