• Hi. As for my opinion, if there is chemical interaction then we can address it in that way. To add into the data, you can take let say FTIR or XPS for CNT, polymer being used, the third one is the hybrid. Hope it is useful.

Thanks Hamzah,

Yes their is the interaction between CNT and polymer matrix during composite formation. 

Yes. If you electropolymerize one monomer over another conducting polymer, a composite is formed, and it may be considered a hybrid material. 

Nevertheless, the term "hybrid" is more characteristic to designate the materials containing organic and inorganic part.
