Abstract
Biopolymers produced from various natural botanical resources such as starch, protein and cellulose are regarded as an attractive alternative to petroleum based plastics since they are abundant, renewable, inexpensive, and environmentally friendly. The present work describes the preparation and characterisation of starch based bionanocomposite films using glycerol as plasticiser. Starch based biodegradable polymers have great commercial potential for bio-plastic, but some of the properties like brittleness, low heat distortion temperature, high gas permeability, low melt viscosity for further processing, etc. restrict their use in a wide- range of applications. With the aim of improving thermomechanical properties, decreasing water sensitivity of polymers and to preserve the biodegradability, nano fillers are being used as renforcing agents. The prepared nanocomposite films were characterized to understand their mechanical, hydrophilicity, antibacterial and biodegradability properties. This work provided a green approach for the preparation of biodegradable materials based on naturally occurring biopolymers.
