An innovative method has been developed to make nanofiller with a surface anchored polymeric chain. The grafting from RAFT polymerization strategy has been utilized to graft poly (N‐vinyl imidazole) (PNVI) chains on the silica nanoparticles surface. Control over the polymer chain length and the grafting density on the particles surface enabled the preparation of size‐tunable nanoparticles. Proton exchange membrane fabricated from the nanocomposite of polybenzimidazole with these nanofillers displayed significant improvement in various physical properties. The image from Tushar Jana and colleagues on page 365 shows nanoparticles of ∼60 nm size in which ∼750 repeat unit of PNVI chain is anchored. (DOI: 10.1002/pola.28917 )
