Fouling experiments performed using BSA indicated that PLA-PEG-PLA copolymers with longer PEG segment lengths were more effective in improving the antifouling properties of the hollow fiber membranes, because of the higher retention of the synthesized copolymer additive in the membrane. 77, No. Crystallized parts showed improved thermal resistance at temperatures above PLA's glass transition. This effect is enhanced not only by the low molecular weight but also by its higher content. Lactic acid as the raw material is produced by fermentation of glucose or sucrose and is refined to a high purity. In this review is designed to give more focus on market growth of this important organic acid and to provide an overview on the recent applications of lactic acid in both medical and pharmaceutical industries. However, it displays low barrier properties to use packaging applications compared with conventional polymers. Applications of PLA have been developed as food packaging material, textiles, and recently also as engineering plastics. The annealed samples containing glycerol had the highest crystallinity. Wu et.
