OH Functionalized MWCNTs
OH-Functionalized MWCNTs
OH-functionalized Multi-Walled Carbon Nanotubes (MWCNTs) have enhanced properties due to the introduction of hydroxyl (-OH) groups on their surfaces. This modification improves their dispersion in various solvents, increases their reactivity, and enhances their interactions with other materials.
Key Features of OH-Functionalized
Hydrophilicity: The introduction of hydroxyl groups makes the surface of MWCNTs more hydrophilic, allowing them to disperse more easily in aqueous solutions and interact more effectively with water-based materials.
Increased Surface Reactivity: The -OH groups make the surface of the MWCNTs more chemically reactive, which facilitates the attachment of functional molecules, drugs, or other nanoparticles.
Improved Dispersion: The hydrophilic nature allows for better dispersion in composites, polymers, and biological systems, which is crucial for achieving uniform material properties.
Enhanced Biocompatibility: The hydroxyl groups improve the biocompatibility of MWCNTs, making them more suitable for biomedical applications such as drug delivery, imaging, and diagnostics.
Increased Surface Area: The functional groups enhance the surface area of MWCNTs, which is beneficial for applications requiring high interaction surfaces, such as sensors and catalysts.
Applications:
Nanocomposites
Polymer Reinforcement: OH-functionalized MWCNTs are widely used to enhance the mechanical properties of polymer-based composites. The increased hydrophilicity ensures better dispersion and stronger interactions between the nanotubes and the polymer matrix, improving strength, toughness, and thermal stability.
Conductive Nanocomposites: When incorporated into conductive polymers, the OH-functionalized MWCNTs increase the overall electrical conductivity of the composite, which is valuable in applications such as flexible electronics, conductive coatings, and sensors.
Biomedical Applications
Drug Delivery: OH-functionalized MWCNTs are used as carriers for targeted drug delivery. The hydroxyl groups make it easier to attach therapeutic agents like anticancer drugs, proteins, or other bioactive molecules to the surface, allowing for precise targeting and controlled release.
