Carboxylated multi-walled carbon nanotubes (MWNTs) (short) 20-30 nm

Carboxylated multi-walled carbon nanotubes (MWNTs), also known as carboxyl-functionalized MWNTs or simply carboxylated CNTs, are a special type of carbon nanotubes. They are characterized by multiple concentric layers of graphene cylinders. The carboxyl groups (-COOH) on their surface make them unique. These nanotubes have gained significant attention in recent years due to their remarkable properties and wide range of potential applications.

Discovery and Development: Carbon nanotubes were first discovered in 1991 by Dr. Sumio Iijima. Since then, researchers have been exploring ways to modify their surface properties to enhance their functionality. Carboxylation is one such modification that has proven to be highly beneficial.
Chemical Composition: The primary component of carboxylated MWNTs is carbon. The addition of carboxyl groups introduces oxygen-containing functional groups, which can interact with various other molecules and materials.
Market Demand: With the increasing focus on sustainable and high-performance materials, the demand for carboxylated MWNTs has been growing steadily. They are used in industries ranging from electronics to biomedicine, contributing to the development of innovative products and solutions.
