Dispersion of Nanotubes in Polyethylene Matrix

A good dispersion of CNTs in polymer matrices can be achieved by the following techniques  

Stirring It is a common technique to disperse particles in liquid systems and can be used to disperse nanotubes. Size and shape of the propeller and the mixing speed control the dispersion result. After intensive stirring of CNTs in epoxy resin, a relative fine dispersion could be achieved (Sandler et al. (39)). 

Calendering The application of a mini-calender to disperse of CNTs in a matrix is a promising technique (Gojny et al. (40)). Besides the improved dispersion results, the efficient manufacturing of larger amounts of nano-composites is also possible.
