Abstract

Composite is a material that made off more than one material to modify and form the combination of the best characteristics of its constituents. The composite material is interesting for further study since this material is not found in nature. Generally, the composite has several advantages such as it has good strength, resistant to high temperatures, and easy to modify according to its applications.The aim of study is to synthesis composite made off natural bentonite and chitosan with some experimental variables such as the weight ratio between the bentonite and chitosan and time processes. The study is to obtain the best operating conditions that will produce a composite material with desired characteristics. The composite was synthesized by reacting chitosan in dilute acetic acid and bentonite suspension by varying ratio of bentonite to chitosan for several reaction times at different pre-treatments. The composite materials was characterized by FTIR to determine the functional groups of composite, XRD to identify the change on material structure and also SEM to characterize composite morphology. The optimum composite was obtained at ratio of bentonite to chitosan 1 : 2 and 12 hours reaction.
