What is OH-SWCNT?

OH-SWCNT stands for Hydroxyl Single-Walled Carbon Nanotubes, a chemically functionalized form of single-walled carbon nanotubes in which hydroxyl (-OH) functional groups are attached to the nanotube surface. The addition of hydroxyl groups improves compatibility with polymers, resins, biological systems, and various solvents while preserving the exceptional intrinsic properties of single-walled carbon nanotubes.

Single-Walled Carbon Nanotubes consist of a single graphene sheet seamlessly rolled into a cylindrical nanostructure. These nanotubes exhibit extraordinary electrical conductivity, extremely high tensile strength, low density, flexibility, and excellent thermal conductivity.

However, pristine SWCNTs often suffer from poor dispersion due to strong van der Waals interactions that cause nanotube aggregation. Hydroxyl functionalization overcomes this limitation by increasing hydrophilicity and improving interfacial interactions with surrounding materials.

As a result, OH-SWCNTs have become one of the most widely used functionalized nanomaterials in advanced research and high-performance industrial applications.

Physical Properties of OH-SWCNT

Hydroxyl-functionalized Single-Walled Carbon Nanotubes retain the exceptional intrinsic properties of pristine SWCNTs while providing enhanced compatibility with various materials and solvents. These properties make OH-SWCNT one of the most versatile nanomaterials for advanced technologies.
