fabrication of alginate-carboxymethyl cellulose blend beads via titanium(iv) oxide/covalent organic frameworks hybrids under ultrasonic irradiation

In the present study, the novel titanium(iv) oxide/covalent organic frameworks (tio2/cof) hybrid was introduced to alginate-carboxymethyl cellulose (alg-cmc) blend beads. the physicochemical properties of each sample were determined by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction, and field emission scanning electron microscopy (fe-sem) analyses. ft-ir spectra of alg-cmc/tio2 and ag-cmc/tio2/cof represented the hybrid materials in the bio-nc beads. moreover, tio2 nanomaterials had an anatase crystality in the alg-cmc matrix, and the crystal formation of these nanomaterials did not show any change in this blend polymer. also, the morphology of these bio-nc have completely changed by adding tio2 and tio2/cof hybrid indicating that this hybrid could widely disperse in the alg-cmc blend beads.
