Identification of bound water through infrared spectroscopy in methylcellulose

摘要: This paper describes the interaction of water with solid polymers. A portion adsorbed in hydrophilic materials is strongly bound to individual sites (bound water), while an additional amount less firmly polymeric chain (free water). Both, free and water, have been subject many studies that uncovered, some cases, qualitative evidence presence water. In this we report a method quantify fraction first layer contact material. The measurement was carried out on infrared spectroscopy data methylcellulose films exposed several humid environments. quantification based determination change natural vibration frequency brought about by molecules solid.
