Applications:
Biomedical & Biosensing: Shortened length and carboxyl functionality improve aqueous dispersibility and enable covalent bonding with biomolecules. Ideal for biosensors, drug delivery, and bioimaging, especially in systems requiring stable, low-toxicity nanocarriers.
Catalysis & Surface Chemistry: The -COOH groups facilitate strong interaction with metal ions and catalytic species, enhancing performance in heterogeneous catalysis, photocatalysis, and template-assisted synthesis. Short tubes offer higher edge reactivity and accessible surface sites.
Polymer & Composite Integration: Short SWCNTs with carboxyl groups disperse efficiently in polar solvents and polymer matrices, improving mechanical reinforcement, thermal stability, and electrical conductivity in advanced composites. Their reduced length supports uniform distribution and processability.
Energy Storage & Conversion: Functionalized short SWCNTs enhance electrode–electrolyte interface behavior in supercapacitors, lithium-ion batteries, and fuel cells, supporting faster charge transfer and improved cycle stability. Their morphology enables better packing and active surface exposure.
