“…In the upper‐layer coating, the cross‐linked underlayer is not affected by the solvent of the upper layer, and it makes the fabrication of multilayer OLEDs possible. The cross‐linkable groups chosen for previous studies include thermally and/or photochemically initiated moieties such as acrylates, benzocyclobutenes (BCBs), trifluorovinyl ethers, oxetanes, norborneol, or styrenes . The cross‐linking materials can be divided into two process types: photochemical and thermal.…”

The photochemical process needs photochemical initiators and ultraviolet (UV) radiation for cross-linking, which add the problems of quenching of excitons from radical initiators and causing photodamage to the OLED materials by UV light, respectively.…”

Cross-linkable hole-transporting, host, and electron-transporting materials with a new cross-linking group, uracil, are designed and synthesized. These compounds exhibited good solubility in common organic solvents and excellent solvent resistance after cross-linking at a low temperature of 120 °C. The OLED was fabricated by all-solution processing using cross-linkable synthetic compounds, except for the electrodes. This device exhibited a current efficiency of 39.2 cd A and a power efficiency of 15.3 lm W .

In this study, grafted gelatin with oligoaniline (GelOA) was synthesized and then mixed with Poly (vinyl alcohol) (PVA). Several scaffolds with different ratio of PVA/GelOA were electrospun to fabricate electroactive scaffolds. GelOA was characterized using Fourier‐transform infrared spectroscopy (FTIR); moreover, nanofiber properties were evaluated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscope (SEM) analyses. Nanofibers diameter was decreased with aniline oligomer increment form 300 to 150 nm because of the hydrophobic nature of the aniline oligomer. Aniline oligomer electroactivity was studied using cyclic voltammetry, which exhibited two redox peaks at 0.4 and 0.6. Moreover, aniline oligomer enhancement resulted in melting point increasing from 220°C to 230°C because of the crystallinity increment. To assess the biocompatibility of nanofibers, cell viability and cell adhesion were tracked using mesenchymal stem cell (MSCs). It was revealed that the presence of aniline oligomer leads to enhancing the conductivity, thermal properties and lowering the degradation rate and drug release. Among of different scaffolds, sample with high content of GelOA shows better behavior in physical and biological properties. Accumulative drug releases under applied electrical field at 40 minutes showed that the drug release for stimulated condition is about 33% more than the unapplied electrical field one.

“…During the last decades, polymers and their composites have been continuously displacing the conventional materials, due to their relatively simple processability, low manufacturing cost, and outstanding corrosion resistance . The enhanced physical, chemical, and engineering properties make these materials widely used in the industrial fields, to be specific, the fabrication of the helicopter rotors, wind turbine blades, water blades, aircrafts, sensors, electromagnetic interface (EMI) shielding, and pipelines . In a series of polymers, a segmented copolymer thermoplastic polyurethane (TPU) with hard and soft blocks attracts tremendous attention for both scientific research and industrial applications .…”

A co‐coagulation method combined with hot pressing technique is successfully applied to fabricate thermoplastic polyurethane (TPU) nanocomposites with different contents of carbon nanotubes (CNTs). Obviously, the mechanical and thermal properties of the nanocomposites are improved with increasing the CNT content. In addition, the existence of hydrogen bonding between CNTs and polymer matrix is demonstrated. Furthermore, the influences of impact parameters on solid particle erosion behavior are investigated systematically. The surface roughness and line roughness are also investigated to illustrate the mechanism of solid particle erosion. As elastic nanocomposites, the maximum and minimum erosion rate (ER) occur at 30° and 90°. The ER is relatively small when the impact velocity is at 10 m s−1, then is increased rapidly between 20 and 30 m s−1. As the size of impact particles increases to 300 µm, a rapid increase of ER occurs between 10 and 20 m s−1. All these results indicate CNTs improve the erosion resistance of TPU matrix.
