Abstract
The invention concerns nanofiller composition comprising (i) a nanoparticle; (ii) a plurality of coupling groups bonded to the nanoparticle; (iii) one or more (a) oligomers or (b) organic isocyanate residues bonded to the one or more coupling groups; and, optionally, (iv) one or more dispersing moieties that facilitate dispersion of the nanoparticle bonded to one or more of the coupling groups or organic isocyanate residues; as well as laminates comprising such nanoparticles in at least one layer.
