Development of High Quality Graphene Oxide Manufacturing Technology

https://korean-electronics.com//inquiryJMC, a subsidiary of Kyung-in Synthetic Corporation (KISCO), has developed a technology for manufacturing high-quality graphene oxide. It is expected to contribute to the commercialization of graphene because it can mass-produce various products specializing in various industries such as secondary batteries, automobiles, and packaging at reasonable prices.
JMC recently announced that it has developed highquality graphene oxide manufacturing technology with a research team led by Dr. Yang Woo-seok of the Korea Electronics Technology Institute (KETI) and a research team from Cornell University in the US. JMC introduced the technology at ID TechEx, a special exhibition of graphene materials in Santa Clara, USA on November 14 to 15.
This technology can be used to adjust the lateral size to less than one micrometer (μm) or 20 to 30 micrometers (μm) or more to 40 micrometers or more via a chemical method using an acidic material. The lateral size is the size of one particle layer. Its size can change depending on its use such as rechargeable batteries and lightweight automobile materials. It is technically difficult to develop products with thick layers.
The proportion of graphene oxide monolayer was raised to more than 80%. When graphene oxide is exposed to high temperatures, it is resolved into graphene. Graphene is a nanomaterial that is one layer separated from graphite, a honeycomb-like threedimensional structure. This new material can dramatically increase the electrons’ speed, current speed, strength, and thermal conductivity. It is light, more than 100 times as strong as iron, transparent, and highly elastic. The higher the proportion of the graphene monolayer is than graphite, the better the performance is delivered.
Its metal content is also reduced to be used in electronic materials. A large amount of metal may cause an error when the material is used in a secondary battery or a capacitor.
JMC has been mainly producing BCMB, a major raw material for saccharin, potassium fertilizer, and semiconductor encapsulants. BCMB is a flameretardant, lightweight polymer material for electronic materials that is growing in the global market.
JMC plans to expand cooperation with various companies and institutions in order to commercialize graphene. The growth of the graphene market has been hindered by difficulties in technology development and applications and high unit prices among others. The company has its own technology through which the company can mass-produce and supply high quality graphene oxide at an economical price. To find applications with various organizations and companies, JMC continues research on applications such as the Si-GO anode materials which improve the efficiency of secondary batteries by using graphene, moisture barrier film, and graphene coating for the prevention of metal corrosion.
