摘要: The objective of the present work is to improve surface area aerogel via supercritical carbon dioxide (sc · CO2) treatment and thus obtain chitosan derivative. resulting mesoporous material exhibits typical characteristics aerogels such as high porosity area. were characterized using FTIR, SEM, TEM, thermal analysis. specific areas porosities determined N2 adsorption. antibacterial assays done E. coli. prepared show important properties biocompatibility, non-toxicity, activity, making them suitable for biomedical applications.
