Here, we report the performance of a biodegradable polymer-based Plastic chip Electrode (PCE) as a current collector in supercapacitor applications. Its production was evaluated using two redox materials (conducting polymers polyaniline and poly(3,4-ethylene dioxythiophene)) and a layered material, rGO. The conducting polymers were directly deposited over the Eco-friendly PCE (EPCE) using the galvanostatic method. The rGO was prepared in the conventional way and loaded over the EPCE using a binder. Both conducting polymers and rGO showed proper specific capacitance compared to previous studies with regular current collectors. Electrodes were found highly stable during experiments in high acidic medium. The supercapacitive performance was evaluated with cyclic voltammetry, charge–discharge measurements, and impedance spectroscopy. The supercapacitive materials were also characterized for their electrical and microscopic properties. Polyaniline and PEDOT were deposited over EPCEs showing >150 Fg−1 and >120 Fg−1 specific capacitance, respectively, at 0.5 Ag−1. rGO continued to show higher particular capacitance of >250 Fg−1 with excellent charge–discharge cyclic stability. The study concludes that EPCs can be used as promising electrodes for electrical energy storage applications.

“…However, it is difficult to lubricate WC-Co protective surface coatings, and this difficulty somewhat limits their broader application. In the past, many efforts have been focused on WC-Co coatings lubricated with oils in various environments [3,4]. Unfortunately, the inherent shortcomings of conventional lubricating oils, such as low boiling points, high vapour pressures, and low load-carrying capacities, hinder their practical application for lubricating thermally sprayed WC-Co cermet coatings.…”

In this work, we report on the first thermal spray coatings to consist of graphene oxide (GO) embedded in a WC-12Co matrix. The purpose of these coatings is to release lubricant into the system when needed. These coatings were prepared using detonation gun spraying, and tribological tests of the coatings were performed. The results indicated that a coating containing embedded GO exhibited approximately half the wear rate and a 28% lower friction coefficient than a comparable coating without GO. These results were attributed to the presence of GO platelets adhering to the friction surface that formed a self-lubricating layer.

“…However, steel tends to be corroded in the atmospheric condition causing the consuming of material resources with the gradual deterioration of ecological environment. [1][2][3] Over the course of the past 30 years, intense research efforts have been devoted into the improvement of the corrosion resistance of various forms of carbon steel. All kinds of strategies in particular coating technologies have been proposed to extend the life time of steel constructions and medical implants.…”

The surfaces of nanoparticles of SiO 2 , TiO 2 and Al 2 O 3 have been modified by γ-(2,3-epoxypropoxy) propyltrimethoxysilane (KH-560) in order to achieve proper dispersion of nanoparticles and possible chemical interactions between nanoparticles and polymeric coatings, and then the homogeneous fluoropolymer coatings containing nanoparticles of SiO 2 , TiO 2 and Al 2 O 3 have been successfully prepared on mild steel substrates. The surface morphologies of the coatings were characterised by field emission scanning electron microscopy. The effects of incorporating various nanoparticles on the corrosion resistance of fluoropolymer-coated steel were investigated by potentiodynamic polarisation curve, electrochemical impedance spectroscopy and salt spray tests. The results showed that KH560-modified nanoparticles can decrease agglomeration effectively, and the nanoparticles play a beneficial role in improving the corrosion resistance of the coated steel significantly. In addition, SiO 2 nanoparticles are of the best effect among three kinds of nanoparticles.
