  • Publication number: 20120123020
    Abstract: The present invention deals with a methodology of incorporating carbon nanotubes (CNTs) into an epoxy matrix and thereby producing epoxy-based CNT nanocomposites. Both the pristine and ozonized CNTs are almost homogeneously dispersed into the resin by this approach. Compared with the pristine CNTs (p-MWCNTs), the ozonized ones (f-MWCNTs) offer considerable improvements on mechanical properties within the epoxy resin.

  • Patent number: 7951864
    Abstract: The present invention provides polymer nanocomposites with dispersed nanotubes and methods of making same. The polymer may be a polyether. For example, the present invention provides an effective method to successfully disperse single walled nanotubes (SWNTs) into both Polyethylenoxide (PEO) and its low molecular weight analog polyethylene glycol (PEG) with hydrodynamic percolation at about 0.09 wt % and an electrical percolation at about 0.03 wt % SWNTs at room temperature, and the resulting nanocomposites. The method may include providing a surfactant. Most notably the present inventors achieved a decrease in the melting point of the polymer and a retardation of polymer crystallization due to the presence of the nanotubes.
