New composite materials based on chitosan iodide and organic dyes, such as methylene blue and fuchsine in fucorcin, were synthesized and characterized. The materials showed uniform distribution of dyes, structured porous sponges and films, and antibacterial activity against antibiotic resistant bacteria. These composites have potential applications in various fields.
New composite materials were obtained based on chitosan iodide and organic dyes - methylene blue and fuchsine in fucorcin (Castellani liquid) - by using a simple synthetic procedure. The materials were characterised by scanning electron microscopy, X-ray diffraction, temperature-programmed desorption mass spectrometry, infrared spectroscopy and visible and ultraviolet light spectroscopy. The dyes in the composites were distributed uniformly and did not form separate phases. These composites could form structured porous sponges and films and therefore be used in various fields of application. The materials displayed antibacterial activity against antibiotic resistant gram-positive and gram-negative bacteria.
