AI Technical Summary
Carbon nanotubes tend to aggregate in organic solvents, resulting in poor dispersion stability. Existing dopamine modification processes suffer from imprecise control of reaction conditions and low grafting efficiency, leading to insufficient dispersion stability.
A two-step modification process of dopamine self-polymerization coating and dodecanethiol grafting was adopted. By precisely controlling the dopamine self-polymerization reaction conditions and combining dialysis and freeze-drying treatment, a dopamine-modified carbon nanotube dispersion was prepared to achieve functional modification of the carbon nanotube surface.
It significantly improves the dispersibility and stability of carbon nanotubes in organic solvents, making it suitable for industrial production and meeting the application requirements of composite materials.
