Electrical Conductivity Behavior of Biopolymer Composites

Interest in the study of biopolymer system has been continuously growing as a result of a variety of promising applications such as in electronics, medicine, food packaging, bioplastics, and coating. Characteristics such as being electrically conductive, biosafe, renewable, biodegradable, and carbon neutral have made application of biopolymer important in the production of environment friendly products. However, conventional polymer has been reported to have a few limitations in their properties. Biopolymer itself normally is not conductive. Inorganic nanofillers are being added to the biopolymer matrix to enhance its electrical conductivity which greatly differ from the conventional biopolymer and exhibit unexpected properties. Therefore, different types of nanofillers have been produced for this purpose. The effect of the kind of biopolymer base and also filler material on the electronic conductivity of the composite will probably be investigated and reviewed in this work.Scopu
