Properties of polypropylene microfibres filled with carbon nanotubes and their composites with compatibilizer.

Influence of carbon nanotubes (CNT) and additives of CNT/compatibilizator on regularities of polypropylene/copolyamide (PP/CPA) mixture melts flowing has been investigated. It has been shown that for nanofilled melts the elasticity and longitudinal deformation values increase. It has been found that addition of CN? and compatibilizator furthers PP fiberforming in CPA matrix improving. It is explained by decreasing of interfacial tension at the interface of the components. The latter leads to stabilization of PP liquid streams. The nanofilled PP microfibers with increasing specific surface and hygroscopicity have been prepared. [ABSTRACT FROM AUTHOR]
