Dependence of the probability of positron annihilation with free electrons (Pp) on the concentration of CNTs in a PTFE-based composite obtained in20 by the method of positron annihilation spectroscopy (a). Dependence of the degree of crystallinity of the PTFE–CNTs systems on the filler content obtained from the data of X-ray structural analysis (b). The diameter of the points on the graphs approximately corresponds to the magnitude of the experimental error.
