ABSTRACT

Kappa carrageenan, a biopolymer derived from red seaweeds, a biopolymer that has drawn a lot of interest because of its special qualities and broad range of uses. The goal of this work is to provide a better knowledge of the structural and thermal properties of kappa carrageenan polymeric films by the synthesis and thorough characterization of these films. These propertieswere investigated using a variety of analytical techniques, such as X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), and an examination of the behavior of these films during gelatinexpansion. The FTIR study provided important details regarding the functional groups and chemical makeup of the kappa carrageenan films. SEM pictures gave information on the films' microstructure and surface morphology as well as visible proof of their structural characteristics. Thermal stability, degradation temperatures, and the existence of any additivesor contaminants in the films could all be evaluated thanks to TGA data. The films' degree of crystallinity and crystalline character were clarified by XRD examination. Additionally, the study investigated the relationship between gelatin, a common biopolymer, and kappa carrageenan films. In order to comprehend the suitability and possible uses of these films in the food and pharmaceutical industries—two fields that frequently use mix materials—this interaction was evaluated. The findings of this study may have a big impact on how new packaging materials, medication delivery methods, and biodegradable items are developed. The present study's synthesis and characterisation of kappa carrageenan polymeric films offera thorough comprehension of their characteristics, paving the way for a variety of uses in manysectors. These discoveries add to the expanding field of sustainable and biodegradable materials, which may provide answers to today's environmental problems. Keywords: Kappa Carrageenan, FTIR, TGA, SEM, XRD
