Graphene-reinforced polymeric nanocomposites in computer and electronics industries

Abstract

Graphene is the newest member of the multidimensional graphite carbon family. Graphene is a two-dimensional atomic crystal formed by the arrangement of carbon atoms in the hexagonal network. It is the most rigid and thinnest material ever discovered and has a wide range of uses regarding its unique characteristics. It is expected that this material will create a revolution in the electronics industry. Graphene is a very powerful superconductor as the movability of charged particles is high on it, and additionally, because of the high surface energy and ? electrons being free, graphene can be used in manufacturing many electronics devices. In this paper, the applications of graphene nanoparticles reinforced polymer nanocomposites in the computer and electronics industry are investigated. These nanoparticles have received much attention from researchers and craftsmen, because graphene has unique thermal, electrical and mechanical properties. Its use as a filler in very small quantities substantially enhances the properties of nanocomposites. There are various methods for producing graphene-reinforced polymer nanocomposites. These methods affect the amount of graphene dispersion within the polymer substrate and the final properties of the composite. The application and the properties of graphene-reinforced polymer nanocomposites are discussed along with examples of results published in the papers. To better understand such materials, the applications of these nanocomposites have been investigated in a variety of fields, including batteries, capacitors, sensors, solar cells, etc., and the barriers to the growth and development of these materials application as suggested by the researchers are discussed. As the use of these nanocomposites is developing and many researchers are interested in working on it, the need to study and deal with these substances is increasingly felt.

Green hydrogen generation in alkaline solution using electrodeposited Ni-Co-nano-graphene thin film cathode

“…When graphene is introduced to pure nickel thin film, the electrical conductivity of nickel and its compounds increases by 15%. (KardanMoghaddam et al 2020 ); on the other hand, adding graphene oxide (GO) to the electrodeposition bath, it was possible to significantly increase the electrical conductivity of the nickel thin film produced by jet electrodeposition. Furthermore, it was discovered that the electrical conductivity of the resulting thin film increased as the concentration of GO increased in the electrolysis bath (Ji et al 2018 ).…”

Preparation and Properties of Electrodeposited Ni-B-Graphene Oxide Composite Coatings

“…Graphene, a honeycomb-like sheet of carbon that is only one atom thick, has attracted much attention for several years due to its special configuration and capability, and it is considered a promising reinforcing particle [ 23 , 24 , 25 , 26 ]. However, the homogeneous dispersion of graphene in electrolytes and the electrodeposition of high-performance composite coatings remains a technical challenge due to the high active surface area [ 27 ].…”

Preparation and Properties of Ni–W Composite Coatings Reinforced by Graphene Nanoplatelets

“…Graphene, a one‐atom thick honeycomb‐like sheet of carbon, has caught the attention of researchers in the field of material physics and engineering due to its excellent mechanical, electrical, optical, and thermal properties. [ 26–29 ] Ni‐graphene and nickel‐based alloy‐graphene composite coatings have been successfully obtained by co‐deposition, with the presence of graphene nanoplatelets (GNPs) enhancing the coating microhardness, friction and wear resistance, and anti‐corrosion properties. [ 30–33 ] However, few studies have been undertaken on the electrodeposition of Ni–W/GNPs.…”
