摘要：
The relation between the conductivity and microstructure in normal rubber and the antistatic composites modified by CB are studied by positron annihilation lifetime spectrum(PALS). Result shows that interlayers will be formed in the composites, it is attributed to the interaction between the nano-CB and rubber chains and is related to the conductivity of composites. At the same time the size of the free volume hole in composites will be decreased. It shows that some small free volume holes will be formed in the composites.
