“…In the resulting composite membrane, hydrogen bonding between the surface hydroxyl group of inorganic filler and the pendant sulfonic acid group (-SO 3 H) of Nafion assists the dispersion of filler particles in the host matrix [11,12]. Grafting hydrophilic oligomeric chains to inorganic particles [3][4][5][6][7][8][9][10][11][12][13][14][15] has furthered the preparation technique of Nafion nanocomposite membranes. With the aim of achieving the forestated goal, use of hydrophilic hollow polymer spheres (HPS) as filler is apparently more attractive [16][17][18][19][20][21] because this particulate structure possesses larger interior space for storing water and the porous hydrophilic polymeric shell prevents quick evaporation of water while the membrane is subjected to dehydration [22,23].…”

“…[73], enquanto que para compósitos Nafion-TiO 2 (5 vol%) preparados pela rota sol-gel, a condutividade assume valores aproximados de ~ 0,07 Scm -1 [75]. Tal característica pode estar relacionada com a localização das partículas na matriz polimérica.…”

“…Tal desenvolvimento foi alcançado a partir da síntese de nanocristais de titânia in situ na matriz Nafion [75] e pela a conversão destas partículas de titânia na fase anatásio em nanotubos de titanato de hidrogênio por reação hidrotérmica alcalina [82]. Estes eletrólitos híbridos foram caracterizados por diferentes técnicas visando sua aplicação em DEFCs.…”
