STUDY FILM MATERIALS BASED ON MODIFIED CHITOSAN BY ACROLEIN SCANNING ELECTRON MICROSCOPY AND X-RAY SPECTROSCOPY
Acrolein-chitosan materials (Ak-Chn), obtained by surface modification of films from chitosan by solutions of acrolein of various concentrations, were studied by scanning electron microscopy (SEM) and X-ray spectroscopy. According to the SEM, it is established that ordered micro regions are formed on the Ak-Chn surface.. The X-ray diffraction method was used to estimate the state of chitosan in the materials studied, depending on the concentration of aldehyde solutions.
