Abstract

An easy one pot method is demonstrated for the controlled periodical surface coating of polyethylene over multiwalled carbon nanotubes (MWCNT) by insitu polymerization of ethylene using highly active metallocene catalysts (Cp2ZrCl2 and Cp2TiCl2) in combination with methylalumoxane. The crystallinity of the nanocomposite was increased and its morphology could be tuned from “sausage” like to “shish-kebab” in the presence of CNT depending on the experimental condition and choice of metal atom.

Figure

A convenient one-pot method is illustrated to control the morphology of polymer nanocomposite by simple mixing of metallocene catalyst (Cp2ZrCl2 or Cp2TiCl2) and MWCNT in toluene at normal conditions followed by the activation with MAO. The crystallinity of the nanocomposite is increased and the polymer morphology could be tuned from “sausage” like to “shish-kebab”, depending on the experimental conditions.
