Biodegradable Polymers

The biodegradable polymer/nanofiller nanocomposites substituting the petroleum-based materials can be used for packaging applications with some additional processing. We have developed the poly(lactic acid)/cellulose nanofiber nanocomposites to satisfy the biodegradability and barrier properties. We have achieved not only this two properties but also mechanical properties for flexible packaging applications.

The biodegradable polymer blend investigated in this center is designed to combine the advantages of multiple biodegradable polymers in order to overcome the limitations of individual components, such as poor mechanical strength or limited processability. By carefully selecting and blending polymers like polylactic acid (PLA), polybutylene adipate terephthalate (PBAT), or starch-based materials, the research aims to achieve a balance between flexibility, toughness, and biodegradability. Special attention is given to the interfacial compatibility and morphology of the blend, which are critical factors in determining its overall performance. This study provides valuable insight into the development of sustainable materials for packaging, agriculture, and other single-use applications. 

The biodegradable starch-based insulation foam substituting the expanded polystyrene(EPS) can be used for thermal insulation liners or boxes. We have developed the biodegradable polymer/starch foam to provide thermal insulation properties almost equal or surpassing the EPS.

The thermoplastic starch composites developed in this center aim to serve as eco-friendly alternatives to conventional plastics by utilizing renewable starch-based materials. Through the incorporation of biodegradable plasticizers and natural or bio-based fillers, these composites are engineered to improve the mechanical strength and moisture resistance of native starch. The research explores the processing behavior, interfacial interactions, and end-of-life compostability of the materials, offering insights into their potential for sustainable packaging and disposable product applications.
