Abstract

See full text

A method of manufacturing a nanocomposite includes exposing dry nanoparticles to a dry, solid matrix material or pellets in a container to form a combination which is then agitated by rotating about an axis transverse to a direction of gravity, at room temperature and without grinding objects, to cause a tumbling action between the pellets and the nanoparticles to thereby evenly disperse and coat the nanoparticles directly on outer surfaces of the pellets which remain in a solid phase and of the same size throughout rotating. The method also includes processing the resulting combination, particularly polypropylene pellets and carbon black nanoparticles, by heating to form a viscous combination which is then drawn to form a nanocomposite fiber having carbon black nanoparticles dispersed evenly throughout the polypropylene, with a resulting fiber having a diameter of 30 μm-100 μm and tensile strength of 300-1500% greater than a similar polypropylene fiber produced without the nanoparticles.
