Investigation of Advanced Hybrid PEM Based on Sulfonyl Fluoride PFSA and Grafted Inorganic Nanoparticles

Plasmas in and in contact with liquid for synthesis and surface engineering of carbon and silicon nanoparticles

“…In addition to the OH and Si-O-Si groups, that still remain at the NPs surface, the Si-O-C 2 H 5 groups were formed that is proved by the observation of the bands at 1190 cm −1 , 1085 cm −1 , 2860 cm −1 and 800 cm −1 . In addition the bands at 455 cm −1 and 945 cm −1 were detected attributable to the Si-Si TO vibrations [26] and to the SiOH group vibrations [27], respectively. Owing to the large surface area-to-volume ratio, the bare surface of the Si QDs are highly sensitive to the reactions with solvent molecules and thus the uncovered surface readily interacts with the surrounding ethanol resulting in the Si-O-C 2 H 5 formation as it was suggested by Mariotti et al [9].…”
