“…However, when exposed to aggressive media, especially chloride in the environment, aluminum and its alloys inevitably undergo serious corrosion, which considerably hinders their number of applications. Numerous efforts have been made to inhibit metal corrosion, including organic coatings [1][2][3], inhibitors [4,5], cathodic protection [6] and surface modification [7]. Inspired by lotus leaves, a superhydrophobic surface with a water contact angle greater than 150°and rolling angle smaller than 10°, has attracted great attention over the past decades, because it presents significant potential in the fields of selfcleaning [8,9], corrosion resistance [10][11][12], oil-water separation [13] and energy conservation [14].…”

A superhydrophobic surface featuring high roughness and low surface energy is designed for effective corrosion protection on aluminum via a facile and cost-effective electrochemical route. The effects of the electrolyte composition and electrodeposition time on the surface wettability were investigated. Moreover, the corrosion resistance performance of the as-prepared superhydrophobic aluminum surface was studied using electrochemical impedance spectroscopy and electrochemical noise techniques. The results show that the superhydrophobic aluminum surface obtained at 2 V for 20 min has a high static water contact angle of 155.8°. Both the average corrosion rate and pitting intensity are remarkably inhibited by the as-prepared superhydrophobic surface on aluminum. Moreover, the static water contact angle for the obtained superhydrophobic surface remains above 150°after exposure to 3.5 wt% NaCl solution for 30 days. This facile and economical superhydrophobic surface, with its excellent anti-corrosion property and stability, shows significant potential for use in industrial applications.

“…In comparison with polyolefin families, hydro‐catalytic degradation rate of PVA can be tuned to targeted tissue. PVA exhibits a proper hydrophilicity role in cell attachment while this property in polydimethylsiloxane (PDMS) and other thermoplastic polymers are very weak . Various types of polymeric scaffolds can be generated by many methods.…”

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.
