Abstract
Provided is a method for the production of a reinforced polymer, which method comprises: (a) introducing carbon nanotubes into a polymer to provide a mixture of the polymer and the nanotubes; (b) stretching the mixture at or above the melting temperature (Tm) of the polymer to orient the carbon nanotubes; and (c) stretching the mixture in the solid state to further orient the carbon nanotubes.
Claims10
A method for the production of a reinforced polymer comprising:
- (a) introducing carbon nanotubes into a polymer to provide a mixture of the polymer and the nanotubes;
- (b) fiber melt spinning, extruding thermoforming or injection molding the mixture at or above the melting temperature (Tm) of the polymer whereby the mixture is stretched;
- and
- (c) drawing the mixture at or above the glass transition temperature (Tg) of the polymer to form a fiber or sheet whereby the mixture is further stretched.
