Water Dispersion of SWCNT for Reinforcement Composite
SWCNT content: 2%, or we could do your required spec.
Introduction of water dispersion swcnt:
1. The insolubility of SWNT in either water
or organic solvents has prompted research efforts focused on nanotube
functionalization combined with dissolution in organic solvents, or mixtures of
organic solvents and water.
2. Water dispersions of SWNT will have
important implications in fields such as biochemistry and
biomedical engineering, in which organic
solvents cannot be used due to evident incompatibilities with living organisms.
3. Most recently, water-soluble SWNT
started to become feasible by functionalization with amines and DNA adducts. However,
it has been demonstrated that surface modifications after functionalization can
affect the inherent electrical, mechanical, and optical properties of the
nanotube. Thus, major attention is being directed at the study of surfactants,
which can successfully suspend carbon nanotubes without the formation of
chemical bonds.
4. In the case of polymer composites,
surfactant, dispersions of SWNT may facilitate the incorporation of individual
nanotubes into the matrix for reinforcement of the composite materials.
