Schematic illustrating the effect of functionalization on filler dispersion in a polymer matrix. (a) Without functionalization, agglomeration of the nanofillers are evident due to high surface energies of the fillers. (b) With functionalization, targeted interactions can be established between the matrix and fillers, increasing the inter-particulate distance [d] and improving dispersion.
