摘要
This work considered the utilisation of environmentally friendly biodegradable materials instead of conventional polymeric materials, in order to prevent further environmental endangerment by accumulation of non-biodegradable materials. Thermoplastic starch (TPS) is an exemplary environmentally friendly biodegradable material. Blending TPS with other biodegradable polymers such as biodegradable polyesters; polylactic acid (PLA) and polycaprolactone (PCL), was recognised as a successful strategy to provide a renewable, fully biodegradable and cost-effective materials. Namely, PLA, PCL and TPS polymeric materials individually show some shortcomings, which can be surpassed by blending. Using economically viable procedure, one can produce multicomponent polymeric materials complying with functional performance requirements while achieving complete biodegradation. Accordingly, PLA/PCL/TPS ternary blends with compositional variations were prepared and investigated in terms of structural, morphologic, mechanical, thermal, physicochemical (water absorption, contact angle) and processing properties in order to discuss and elucidate optimal performance of the overall material. In summary, this study could lead to a better understanding of performance behind different blends and ensure producing and using a new generation of biodegradable plastics that will not burden our environment.
