The motivation of the studies was to investigate the relationship between the properties of carbon nanotubes CNTs and their modification with metallic coating on the possibility of obtaining improved epoxy resins with aligned nanotubes for the exploitation of their enhanced electrical and mechanical properties. In order to obtain improved directional conductivity we tried to arrange nanotubes in polymer matrix using magnetic field.

Magnetic properties of nanotubes were modified by ferromagnetic layer of Ni-P. Carbon nanotubes surface was prepared for Ni-P electroless deposition. Multiwall nanotubes CN3100 from Nanocyl® were used. The Ni-P coating on the purified CNTs grew along the nanotubes while on the untreated CNTs grains of Ni-P formed agglomerates at the surface. Depending on the process conditions, nickel content varied in the range of 30-60%wt. The solution reaction (pH=8.5) and the basic composition of the solution led to the deposition of Ni-P coatings with a low phosphorus content of 1.5-3.0%wt..
