Recent Developments in Bio-nanocomposites: A Review

Bio-nanocomposites, are made of biopolymers and inorganic solids, having dimensions in the nanometer range (1–100 nm). A wide range of available biopolymers and inorganic nanoparticles offers means of developing different bionanocomposites with different structural properties, functionalities and applications. This is achieved by mixing nano particles in various combinations. Biopolymers form the matrix, determining the shape and structure of bionanocomposites. Interface also plays a very important role in determining the resultant properties of these types of composites. Dispersed nano - particles modify the matrix resulting in improved properties. Considering these versatile properties this review focuses on synthesis, characterization and applications of bio-nanocomposites. All the technical and scientific issues have been addressed highlighting the recent advancement.
