PREPARATION AND PHYSICOCHEMICAL CHARACTERISTICS OF AN IODINE AND BISMUTH CONTAINING COMPOSITE MATERIAL BASED ON CHITOSAN

Abstract

We created composite materials by using a straightforward method, combining chitosan, iodine, and bismuth. We used two chitosan with two different molecular masses. We used iodine in the composites as chitosan iodide and bismuth in the form of tetraiodobismuthanuide. We analysed the resulting materials with scanning electron microscopy, X-ray diffraction, temperature-programmed desorption mass spectrometry, and visible light spectroscopy. We observed that bismuth and iodine were evenly distributed throughout the composites and did not separate into distinct phases. These composite materials have the ability to form organised porous sponges, making them suitable for a wide range of applications in different fields.
