Product Detail

While there’s no question that graphene has a wide range of positive attributes, one of its downfalls is its generally small flake size. Since graphene usually comes in miniscule flakes, its electrical conductivity and mechanical properties are somewhat hindered, which can be a major problem for businesses that heavily depend on their electrical equipment. Luckily, ACS Material can provide you with large-size graphene oxide that retains commercially viable properties that are well suited for a number of industry applications. Whether you’re creating nonlinear optical materials for ultrafast optoelectronics or hoping to develop a large-scale production of graphene, large-size graphene oxide makes for a great semiconductor or insulator.
