Graphene has a two-dimensional structure of a carbonaceous new material. Graphene has excellent electrical, thermal and mechanical properties. Graphene oxide (GO) is a unique material with various oxygen containing functionalities such as epoxide, carbonyl, carboxyl and hydroxyl groups. Interest in GO increased dramatically after graphene, It was initially hoped that GO might be a synthetic precursor to graphene.

The Graphene Oxide water dispersion is a GO nano liquid paste with a higher graphene oxide concercentration. The primary application for this product is for making concrete structures. This product shall be mixed with concrete at a proportion of 0.03 W/w% ratio. For making one kg concrete mixture by adding 500 mg of the GO, the strength of the concrete will increase into 25 to 30% higher rate. The GO dispersion will insulate the entire concrete stucture providing anti water penetration possiblities, hence it protects the steel bars from corrosion so the life of the concrete structure increases. Secondly, with the use GO water dispersion, industries can manufacture high strength fibers, composites, etc.
Graphene Oxide is a two dimensional nano material. It is synthesised from graphite material. Its applications are very wide, bio sensors, solar cells, flexible electronic circuit boards, concrete admixture, and various other products. The graphene oxide shall be reduced into reduced graphene oxide which is having great mechanical and thermal properties. Hence, in recent years its usage is growing fast in various industrial applications to improve thermo, electric and mechanical properties.
