Abstract/Summary This paper reviews the development of biodegradable thermoplastic starch polymers at the University of Queensland. Biodegradable plastics are of significant current interest in the packaging and plastics industry. Starch-based thermoplastics are relatively cheap and more importantly manufactured using a renewable resource. However traditionally most thermoplastic starch polymers suffer from low water resistance and loss of mechanical properties when in contact with water. Next generation plasticised thermoplastic starch polymer blends have been developed to overcome these limitations. This paper highlights the fundamental understanding of structure-property relationships [1,2] and structure-degradation relationships [3] in thermoplastic starch polymer blends. In this work we specifically highlight effects of interactions between starch and blend components such as plasticisers and other polymers, and the subsequent effect on polymer structure. From this structural understanding we examined the subsequent effects on physical properties, final mechanical properties, water diffusion, enzymatic degradation and biodegradation.
