Abstract

Presentwork is devoted to investigation of structure and functional properties of hybrid nanomaterials based on
the TiO2-modified cellulose fibers of cotton. The titania hydrosol was successfully prepared using the titanium
tetraisopropoxide as precursor and the nitric acid as peptizing agent via the low-temperature sol–gel synthesis
in aqueous medium and applied to cotton fabric. For cross-linking of titania nanoparticles to cotton the 1,2,3,4-butanetetracarboxylic acid (BTCA) was used as a spacer. The morphology and composition of the surface pure and TiO2 modified cotton fibers were investigated by the scanning electron microscopy (SEM). The cotton/TiO2
composite was characterized by the dielectric permittivity. For the estimation of total titania concentration, all samples were calcined at 650 °C. The antimicrobial activity of the treated TiO2 cotton fibers was investigated against Escherichia coli as a model Gram-negative bacteria after exposure to UV-irradiation for 10 min
