A facile route of making silica nanoparticles-covered graphene oxide nanohybrids (SiO2-GO); fabrication of SiO2-GO/epoxy composite coating with superior barrier and corrosion protection performance

Carbon nanomaterials are receiving worldwide attention because of their multi-faceted superiority in thermal conductivity, flame retardancy, mechanical stability, electrical conductivity, and biocompatibility. In this review, a survey of the literature on extending performance of epoxy resins based on carbon nanomaterials is presented. The structure-performance relationships for different carbon nanomaterials modified epoxy are closely analyzed. The performance extension in mechanical, electrical, thermal conductivity, flame retardancy, antidegradation, and tribological properties of epoxy are reviewed in detail. Other application areas including biocompatibility, biodegradability, gas barrier properties, shape memory, and electromagnetic interference shielding are touched. The challenges and opportunities in carbon nanomaterials functionalized epoxy composites are also discussed.

A review of extending performance of epoxy resins using carbon nanomaterials

Enhancement of barrier and corrosion protection performance of an epoxy coating through wet transfer of amino functionalized graphene oxide

Multi-walled carbon nanotubes (MWCNTs) directly grown on a stainless steel mesh were functionalized using a fast, solvent-free radiofrequency (RF) plasma technique. Two different gas mixtures of Ar/C2H6/O2 and Ar/C2H6/N2 were used to add oxygen- and nitrogen-containing functional groups to the surface of MWCNTs. The binder-free forest-like MWCNTs before and after functionalization were tested as supercapacitor electrodes. The structural and electrochemical characteristics of the electrodes were evaluated. The RF power (10–30 W) and functionalization time (1–20 min) were optimized to achieve the highest capacitance. Both nitrogen- and oxygen-functionalized MWCNTs showed improved capacitive behavior due to the presence of the functional groups on the MWCNT surface. The highest capacitance was obtained for the MWCNT electrode functionalized with the RF plasma employing the Ar/C2H6/O2 gas mixture at 20 W for 15 min, reaching the specific capacitance of 37.3 ± 1.1 mF cm−2 (196.3 ± 5.8 F g−1).
