Polylactic Acid: Synthesis, Properties and Applications L
and Ruan, R., 2009, Polylactic acid (PLA) synthesis and modifications: Polylactic Acid (PLA) Bioploymer - Bored of StudiesIf anyone has any information on Polylactic Acid please let me know!
Lactic acid occurs widely in nature and is produced by many life forms from bacteria to human cells. Identified in 1780 as a component of sour milk, it has been used in food, drink, pharmaceutical, cosmetics, chemical and electronic industries in different forms, such as free acid (typically 80–92% in water), salts (e.g., calcium lactate), and esters (e.g., ethyl lactate). If one calculates the amount of its derivatives back to the equivalent amount of original lactic acid, the total global market volume in 2008 is estimated at around 260,000 tons of lactic acid (calculated at 100% concentration) for traditional applications [excluding poly(lactic acid) (PLA)]. PURAC has a market share of over 60%, and other producers share around 30–40% of the global commercial market for lactic acid and its derivates. Whereas lactic acid was historically produced through a chemical process, today more than 95% of the lactic acid produced is derived from biological resources (e.g., sucrose or glucose from starch) by microbial fermentation, which typically produces the (+) form of lactic acid. Only one producer still uses petroleum-based chemicals to synthesize racemic mixture of the (−) and (+) forms of lactic acid.
Polylactic Acid: Synthesis, Properties, and Applications
Compared with traditional petroleum-based plastics, PLA is still more expensive and usually has less desirable mechanical and physical properties, which limit its commercialization and applications. The recent commercialization of (−)-lactic acid and lactide has the potential to improve the mechanical and thermal characteristics of PLA resins and blends by the crystallization of stereocomplex PLA, which allows application in previously unattainable high-end markets.
