ABSTRACT
Conductive properties of TiO(2) nanoparticles and TiO(2)/BC hybrid inorganic/organic fibres were investigated by electrostatic force microscopy (EFM). TiO(2)/BC hybrid composites were prepared based on bacterial cellulose produced by Gluconobacterxylinum, being the bacterial cellulose as a hydrophilic substrate for TiO(2) nanoparticles synthesized via sol-gel. Taken into account hydrophilic nature of the cellulose, TiO(2) nanoparticles were located on the surface of the fibres due to hydrogen bonding interactions. EFM was used to determine qualitatively conductive properties of TiO(2) nanoparticles and their TiO(2)/BC hybrid inorganic/organic fibres. Results indicate that TiO(2)/BC hybrid fibres respond to applied bias regardless of the sign of the applied voltage.
