Abstract: 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 ?m-100 ?m and tensile strength of 300-1500% greater than a similar polypropylene fiber produced without the nanoparticles.

Abstract: A method of manufacturing a nanocomposite includes exposing a plurality of substantially dry nanoparticles to a substantially dry and solid matrix material to form a combination of the nanoparticles and the matrix material. The method also includes agitating the combination of the nanoparticles and the matrix material to thereby disperse the nanoparticles on the matrix material. The matrix material remains in a solid phase during agitating. Furthermore, the method includes processing the combination to form the nanocomposite having the nanoparticles dispersed in the matrix material.
