Hydropropylcellulose (HPC)-modified multi-wall carbon nanotubes (HPC-MWCNTs) were prepared by physical adsorption of HPC on the surface of MWCNTs. The modification decreased the contact angle of water on HPC-MWCNTs and increased their water dispersion ability. However, HPC-MWCNTs dispersed in water were not stable and precipitated on the bottom of the container after 2 days as cylindrical bundles with a diameter of 4-8μm and a length of 25-35μm. The cylindrical bundles were formed by self-assembly of HPC-MWCNTs by hydrophilic and hydrophobic interactions.Hydropropylcellulose (HPC)-modified multi-wall carbon nanotubes (HPC-MWCNTs) were prepared by physical adsorption of HPC on the surface of MWCNTs.
