Hydroxyl Multi-Walled Carbon Nanotubes

Biomedical Applications

Drug Delivery Systems:
Hydroxyl-functionalized MWCNTs are used as drug delivery carriers due to their enhanced water solubility and biocompatibility. The hydroxyl groups on their surface make them more reactive and allow for the attachment of therapeutic molecules, such as anticancer drugs, antibiotics, proteins, or genes.

Biosensors:
OH-MWCNTs are utilized in the development of highly sensitive biosensors. The hydroxyl groups enable the attachment of biological recognition elements (e.g., antibodies, enzymes, or DNA strands), making these nanotubes ideal for detecting specific biological or chemical targets.

Energy Storage and Conversion

Supercapacitors:
OH-MWCNTs are commonly used in the fabrication of supercapacitors, which store energy and offer high power densities. The functionalized MWCNTs improve the interaction with electrolytes, resulting in enhanced charge/discharge performance, higher energy storage capacity, and longer cycling stability. OH-functionalized MWCNTs are used to enhance the electrochemical performance of supercapacitors by improving conductivity and providing better electrode-electrolyte interface interactions.

Batteries:
In the development of advanced batteries, such as lithium-ion batteries or sodium-ion batteries, hydroxyl-functionalized MWCNTs are used to improve the conductivity and stability of electrodes. The hydroxyl groups help to increase the interfacial bonding between the MWCNTs and active materials, enhancing the overall performance, charge capacity, and cycle life of the batteries.

Fuel Cells:
OH-MWCNTs are also applied in fuel cell technology to improve the electrochemical activity of catalysts used in fuel cells. The hydroxyl groups facilitate the attachment of metal nanoparticles (e.g., platinum), which act as catalysts, enhancing the performance and efficiency of fuel cells, especially in terms of conductivity and durability.

Environmental Applications

Water Filtration and Purification:
OH-functionalized MWCNTs are effective in water purification applications due to their ability to adsorb pollutants like heavy metals, organic dyes, and other contaminants.
