Investigation of spectroscopic, water barrier and thermal characteristics of ameliorated chitosan membrane

Abstract

The present research focuses on the ameliorated chitosan membrane (ACM) in which chitosan based membrane has been developed by optimization of different synthesis parameters such as the amount of solvent, amount of monomer and amount of initiator in which maximum percentage grafting of 812% is achieved. The synthesized membrane is further investigated for the evaluation of spectroscopic, water barrier and thermal characteristics. The spectroscopic studies are carried out using FTIR spectroscopy and UV-visible-NIR absorption spectroscopy which is used for evaluating the chemical characteristics. Water barrier characteristics are evaluated using a water absorption test and water contact angle in which water absorption of 1175% in 180 min and water contact angle of 77.59° indicating a hydrophilic nature whereas the thermal characteristics are evaluated using TGA and DSC studies which confirmed the thermal stability of 22.92% at 800°C.
