Polystyrenes end-functionalized with 1,1-dihydroperfluorotetradecyl (DHPTD) groups were synthesized using the corresponding ATRP initiators. Nanoindentation measurements at ambient conditions showed increases of about 80 and 300 percent in the storage and loss moduli respectively compared with the unfunctionalized PS samples. Despite relatively modest increases in E' and E'' for the 28k DHPTD-functionalized PS at ambient conditions, at temperatures between 150 and 180 0C the shear storage modulus (G') of the DHPTD modified polystyrenes (28K) is between one to two orders of magnitude larger than the matching PS homopolymers whereas the shear loss modulus (G'') was 50% higher.
