Abstract:
Water-based chitosan are developed for biomedical applications by simply mixing chitosan and HOBt (1-hydroxybenzotriazole monohydrate) with WSC (l-ethyl-3-(3-methyl-aminopropylcarbodiimide) hydrochloride) at room temperature. The clay and modified clay are used as enhancement fillers. The chitosan-clay aerogel is directly prepared from hydrogel. It was found that when clay is cooperated into the system it can improve appearance of gels, thermal properties and decrease swelling ratio of chtiosan aerogel.
