Protection of Glass from Corrosion with Graphene

Studies in the Center of Multidimensional Carbon Materials (CMCM), within the Institute for Basic Science (IBS) have shown protection of glass from corrosion by graphene coating.
Glass is a most common packaging material for protection of medicine and chemicals due to its high degree of resistivity towards corrosion and chemicals. However, some glass types can corrode over time at high humidity and pH conditions which will cause to decrease in its transparency and strength. Therefore, silicate glass corrosion under high humidity is a most serious problem especially for pharmaceutical, environmental and optical industries in hot and humid climates.
With the adsorption of water on the glass surface, hydrogen ions of water diffuse into glass and exchange with the sodium ions present in the glass surface. Then, pH of the water near the glass surface increases leading to dissolving of silicate structure of glass. To protect the glass surface, thin, transparent and good barrier material to chemical attack are needed for an ideal protective coating. Single layer Graphene with its chemical inertness, thinness and high transparency makes Graphene very promising for the coating of glass surface. In addition, Graphene can act as barrier for the chemical attacks. Therefore, Graphene can be used as protective layer for corrosion, oxidation, friction, bacterial infection, electromagnetic radiation etc.
According to the research at IBS, one or two atom thick layer can protect the glass from corrosion and scientist says that if the production of large amounts of higher quality graphene sheets on the glass surface is reached, then graphene coating on glass will be applicable in industrial scale.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from:  https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread th...

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs)  have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
