Title : Poly (lactic acid): Polymer for the Future

Bio-based polymers are materials such which are produced from renewable resources and currently hold a small fraction of the total global plastic market. The worldwide interest in bio-based polymers has accelerated in recent years due to the desire and need to find non-fossil fuel-based polymers. One such bio-based polymer which is also biodegradable is polylactic acid (PLA), which is derived from sustainable resources. Due to the good mechanical strength and low toxicity, PLA is considered to be a potential replacement for petroleum based plastics used for various commodity applications. Although PLA has been the focus of much research for nearly decades, their production has still not reached the level of PE, PET and PP due to cost. Lactic acid is not as readily available compared to the starting materials used for current plastics. Despite PLA’s shortcomings, interest in this material has not waned due to its faster degradation time compared to current plastics, which is believed to prevent its accumulation in our environment if implemented on an industrial scale. The other weaknesses of PLA are poor thermal properties limit its applicability at high temperatures, and brittleness. Therefore, further developments are still required before PLA can replace existing plastics. Many researches have been reported on the modification of PLA to further enhance the properties; overcoming the weaknesses without compromising its inherent outstanding properties like good mechanical performances and biodegradability. This presentation will highlight on efforts to reduce the cost of PLA to make it more competitive compared to the commodity synthetic plastics. Besides that, investigations on overcoming the brittleness and poor thermal properties will be discussed. The other important property which is important for PLA to be accepted in many engineering applications is good flame resistance. This aspect will also be covered in this presentation.
