Abstract:

The character of variations of the local electric resistance of film polymer composites on the basis of polyvinyl alcohol with graphite powder from one side and the magnetic susceptibility of the same polymer with nickel nano-particles from another one have been studied. It is established that the changes of these parameters essentially depends on both initial shape of the films and on direction of their orientation. It is concluded that the films of gradiently anisotropic polymer composites may be used in electronics.
