Facile Fabrication of Robust Superhydrophobic Epoxy Film with Polyamine Dispersed Carbon Nanotubes
Nanocomposite films of superhydrophobic surface are fabricated
from the dispersion of unmodified carbon nanotubes (CNTs) and hydrophobic
polyÂ(isobutylene)–amine (PIB–amine). The PIB–amine
prepared from the amidation of polyÂ(isobutylene)-succinic anhydride
and polyÂ(oxypropylene)–amines is essential for dispersing the
originally entangled CNTs into the debundled CNTs as observed
by TEM. A robust CNTs/epoxy nanocomposite film with high dimensional
stability is made by subsequent curing with epoxy resin. The self-standing
film exhibits a superhydrophobic property, with water droplet contact
angle > 152° due to the CNTs controlled alignment on the surface
forming micrometer-size plateaus, as observed by SEM. The preparation
of PIB–amine/CNTs dispersion and subsequently curing into a
superhydrophobic CNTs/epoxy film is relatively simple and can potentially
be applied to large surface coating
