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
Bioplastics

Twin screw extrusion
Characterization and Scale-up
Bioblend
Desired Products
9
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
