(-COOH) Functionalized Short Length Multi Walled Carbon Nanotubes

Purity: > 98%, Outside Diameter: 20-30 nm

Technical Properties

Applications

• Polymer & Nanocomposites: Carboxyl groups improve dispersion and interfacial bonding in polymer matrices, enhancing mechanical strength, thermal stability, and conductivity.
• Energy Storage: Used in lithium-ion batteries, supercapacitors, and fuel cells to improve charge transfer, electrode stability, and cycle life.
• Catalysis & Electrocatalysis: –COOH groups act as anchoring sites for metal nanoparticles and enzymes, enabling efficient hydrogen evolution, oxygen reduction, and nanobiocatalysis.
• Sensors: Functionalized MWCNTs enhance sensitivity and selectivity in chemical and biosensors by facilitating electron transfer and molecular recognition.
• Biomedical Applications: Short-length –COOH MWCNTs show improved biocompatibility and are used in drug delivery, bioimaging, and tissue engineering scaffolds.
• Environmental Remediation: Applied in adsorption of heavy metals and organic pollutants due to high surface area and reactive carboxyl sites.
