Abstract

The interaction of a chitosan biopolymer with the surface of fumed silica was investigated by temperature-programmed desorption mass spectrometry (TPDMS), thermogravimetry (TG), UV–visible spectroscopy (UV/vis), and Fourier transform infrared spectroscopy (FTIR). Mass spectra were used to estimate the number of chitosan segments non-connected and directly connected to the silica surface. The results indicate that as the amount of adsorbed chitosan increases the number of non-connected segments increases. A method was suggested for calculating the p parameter for chitosan adsorbed on silica directly from TPDMS data and without additional sample treatment. The experimental data indicate the formation of supramolecular iodine–chitosan surface complexes arranged in the form of two-layer cylindrically structured units.
