Аннотация: For the first time, the synthesis of water-soluble copper-containing sulfates of microcrystalline cellulose (Cu-MCS) was carried out by ion exchange method. The composition of the obtained products was studied using chemical methods and X-ray spectral microanalysis. The copper content in the obtained Cu-MCS samples was 12.6-14.1%. The absence of sodium in the obtained polymer shows complete substitution of sodium cations on the copper cations in the sodium salt of MCC sulfate. The structure of the copper-containing sulfates of microcrystalline cellulose was studied by methods of X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and electron paramagnetic resonance (EPR). It was shown by XRD, that Cu-MCS and the sodium salt of MCC sulfate had amorphous structure in contrast to the samples of the original MCC, with a high degree of crystallinity. According to EPR data there is a formation of copper-containing salt system with a pseudo-crystalline structure in the samples of Cu-MCS. As shown by atomic-force microscopy, the surface of the Cu-MCS films consists of homogeneous crystallites which have a spherical or slightly extended form and the sizes of about 70 nm. The film surface was quite homogeneous in its phase composition and contained no impurities.
