Bioplastics and Biobased Polymeric Composites

7

Focusing on the blends of biodegradable polymers such as PLA,

PHBV, PBS, PBAT, TPS, PVA, etc. (collaborative with

Assoc.Prof.Dr. Manus Seadan)

Application for packaging and commodity articles

Focusing on developing novel processing techniques to tailor-made

biodegradable polymers e.g. ultrasonic atomizing, supercritical

assisted phase inversion techniques

e.g. Porous films, microparticles and monoliths for tissue

engineering application

More binary and multi-components

1. PLA/SPC (Soy protein)

2. PLA/SPC/TPS (thermoplastic starch)

3. PLA/PBS/Protien

Future work

1. Lignocellulose-based polymeric composites

2. Protien-based polymeric composites

Fundamental research

1. Structure Property Relationship incl. QSAR

2. Thermal resistance e.g. freeze and microwave

3. Solubility determination of bioplastics under high

pressure conditions

New PBS plant (PTT MCC Biochem Company Limited) Cheaper polymers?

What about PLA? Monomers and Lactide - still expensive butWill PLA be getting cheaper?

Cellulose based polymers and derivatives: possible
