Two different examples of compatibilisation strategies used to enhance filler/matrix interfacial adhesion in polymer nanocomposites are discussed. The first strategy was based on the surface modification of multiwalled carbon nanotubes (MWCNT) by a dry mechano-chemical process. The modified nanotubes were used for the realisation of polypropylene/MWCNT composites with improved matrix/nanotubes compatibility. The second compatibilisation strategy was based on the synthesis of a proper coupling agent, realised by modifying polyethyleneterephthalate (PET) chain ends with anhydride groups. This coupling agent was used as a third component for the realisation of PET-based nanocomposites reinforced with precipitated calcium carbonate.

The first strategy was based on the surface modification of multiwalled carbon nanotubes (MWCNT) by a dry mechano-chemical process. The modified nanotubes were used for the realisation of polypropylene/MWCNT composites with improved matrix/nanotubes compatibility. The second compatibilisation strategy was based on the synthesis of a proper coupling agent, realised by modifying polyethyleneterephthalate (PET) chain ends with anhydride groups.
