OH Functionalized MWCNTs (>95%, OD: 10-20 nm)

OH Functionalized MWCNTs

OH-functionalized Multi-Walled Carbon Nanotubes (MWCNTs), with hydroxyl groups (-OH) attached to their surface, have enhanced chemical reactivity and dispersion properties, making them highly useful in various fields. Here are some of the key uses and applications.

Nanocomposites

Polymer Reinforcement: OH-functionalized MWCNTs are used to reinforce polymers, improving the strength, toughness, and thermal stability of polymer-based materials. The hydroxyl groups help improve the bonding between the nanotubes and the polymer matrix, leading to better dispersion and more uniform composite properties.

Improved Dispersion: The increased hydrophilicity from the OH groups allows for better dispersion of MWCNTs in water-based or organic solvents, which is crucial for producing high-quality nanocomposites.

Biomedical Applications

Drug Delivery: The hydroxyl groups on the surface of MWCNTs enable the attachment of therapeutic molecules, such as drugs, proteins, or nucleic acids. This improves the biocompatibility and facilitates the targeted delivery of drugs to specific tissues or cells, enhancing the efficacy of treatments.

Biosensors: OH-functionalized MWCNTs are used in biosensors due to their enhanced surface reactivity, allowing them to bind biomolecules such as antibodies or enzymes. This makes them highly sensitive for detecting specific analytes (e.g., glucose, pathogens, or other biomarkers).

Water Treatment and Purification

Contaminant Adsorption: The hydroxyl groups increase the affinity of MWCNTs for contaminants, making them effective for adsorbing heavy metals, organic pollutants, and toxins from water, improving water purification processes.

Filtration: OH-functionalized MWCNTs can be used in advanced filtration systems due to their ability to interact with a wide range of pollutants, improving water quality in industrial or household filtration systems.

Electrochemical Applications

Supercapacitors and Batteries: OH-functionalized MWCNTs are used in energy storage devices like supercapacitors and lithium-ion batteries. The increased surface area and hydrophilic nature enhance the interaction with electrolytes, improving charge storage capacity, conductivity, and overall performance.
