Method of making a homogeneous mixture of polyolefin solids and carbon solids

A method of making a homogeneous mixture of polyolefin solids and carbon solids without melting the polyolefin solids during the making. The method comprises applying acoustic energy at a frequency of from 20 to 100 hertz to a heterogeneous mixture comprising the polyolefin solids and the carbon solids for a period of time sufficient to substantially intermix the polyolefin solids and the carbon solids together while maintaining temperature of the heterogeneous mixture below the melting temperature of the polyolefin solids, thereby making the homogeneous mixture without melting the polyolefin solids.

Dispersion method for particles in nanocomposites and method of forming nanocomposites

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.
