Biocomposite Materials Based on Chitosan and Lignin: Preparation and Characterization

In this study, bioactive composite systems based on natural polymers (chitosan and lignin) were prepared in study. The structural, mechanical, morphological properties of chitosan-based materials containing various amounts lignin filler investigated. infra-red IR spectroscopy data confirmed the formation chemical bonds between components obtained composites. mechanical film samples studied air physiological solution. It was demonstrated that breaking elongation values wet state higher (150–160%) than corresponding (average) value a pure chitosan (100%). scanning electron microscopy atomic force introduction had caused significant changes surface morphology films. appearance strongly pronounced texture porosity facilitated cell proliferation composites, i.e., bioactivity enhanced with an increasing content matrix.
