“…Nowadays, polymer composite materials are broadly employed as a part of building applications, corrosion and erosion, EMI shielding, energy storage, fuel cells, and sensors because of their incredible physical and mechanical properties. These composites have applications in fields where high imperviousness to wear, scraped spot, and disintegration is required (mining, vehicle, residential gear, aviation, marine, sports, and so on) .…”

Silver nanoparticles/polymer composite (Ag‐NPs/PC) may eventually be biodegradable, sustainable, or burned without production of lethal by‐products and can be utilized as packaging and biomedical device applications. Nanoparticles engaged in pine gum (resin and rosin) are preserved for months without any significant effect on particle size and distribution. This paper focuses on the pine gum/epoxy composites with and without silver nanoparticles fabricated by a hand lay‐up technique. Silver nanoparticles are fixed at 0.37% and pine gum varies from 2 to 24% by weight to acquire the best mechanical and wear properties. The result indicates that Ag‐NPs with pine gum (23.7 wt% resin &13.3 wt% rosin) has the best tensile and impact strength reaching a gain of 51.34% and 53.68% simultaneously. Hardness is noted most extreme 17.92% at Ag‐NPs sample (7.4 wt% resin and 3.7 wt% rosin) and wear resist behavior is best noted with neat pine gum/epoxy composite. The antibacterial assay of the Ag‐NPs is done against Escherichia coli and noted that the zone of inhibition is found to be 1.6 cm as compared to inhibition of 0.4 cm for pine gum reaching an advance of 75%. The various arrangements are enhanced and sited on the basis of TOPSIS technique.

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 .…”

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.
