What is MWCNT-OH (Hydroxyl Multiwall Carbon Nanotubes)?

MWCNT-OH, also known as Hydroxyl Functionalized Multiwall Carbon Nanotubes, is an advanced nanomaterial created by chemically modifying multiwall carbon nanotubes with hydroxyl (-OH) functional groups. This functionalization enhances the surface chemistry of the nanotubes, making them easier to disperse in various solvents, polymers, resins, and composite materials.

Traditional carbon nanotubes often tend to agglomerate because of strong van der Waals interactions. By introducing hydroxyl groups, the nanotubes exhibit improved compatibility with hydrophilic materials, enabling better dispersion, stronger interfacial bonding, and enhanced overall performance in composite systems.

The addition of hydroxyl groups also provides reactive sites that allow further chemical modification, making MWCNT-OH an ideal material for functional coatings, sensors, biomedical research, catalysis, energy storage, and advanced nanotechnology applications.

Due to its remarkable combination of high electrical conductivity, excellent thermal conductivity, outstanding mechanical strength, chemical stability, and improved dispersion characteristics, MWCNT-OH has become one of the most widely researched and commercially utilized carbon nanomaterials worldwide.
