ABSTRACT
In general, composites contain two or m ore components that after combining have different properties both physically and chemically from the individual components. And, in particular, bionanocom posites that are made up of biopolymers and inorganic solids (metal oxides) that lie in the nanoregime size or in the nanom eter range (1 -1 0 0 nm) have novel and multifunctional properties, such as an timicrobial activity, biodegradability, and biocompatibility. They are used in drug release and bioengineering, in electronics, and in packaging of food items and, of course, regenerative medicines [1]. To develop pollution-free materials, constituents of bionanocom posites need to be modified that will help to clean the environment and be easily degradable. Pertinently, on comparison we find that the individual components o f nanocomposites show better prop erties, particularly mechanical, gas barrier, thermal, and flam e-re sistant properties [2-5]. As per the nature, methods of preparation, properties, and other application purposes bionanocomposites are different from simple nanocomposites. Prior to 2 0 0 4 bionanocom posites were studied by Wagner [6], who used silica nanoparticles and natural rubber, which has been acting as a reinforcem ent since long before in 1941.
