PLA mainly through physical modification of the method of blending modification

Physical modification of PLA by blending mainly modification method, PLA weakening of strong Ethyl lactate hydrogen bonding and van der Waals forces, increase the thermoplastic polymer, while reducing production costs. The PLA and PCL, starch, thermoplastic starch, (TPS), poly vinyl acetate (EVA), polymethyl methacrylate (PMMA), poly-β-hydroxybutyrate (PHB), microcrystalline cellulose, polyethylene Ding alkenyl succinate (PBS) and polyethylene glycol (PEG) polymer blends and derivatives thereof to some extent improve the PLA thermoplastic, to improve its mechanical properties. In addition, citric acid esters, phosphate esters, glycerol triacetate, lactide, glucose monomers, half esters of fatty acid, glycerol, and other oligomers of ferrous lactate can be well plasticized PLA, the PLA in biodegradable plastic packaging and other aspects of practical value. In recent years, the use of inorganic nano-materials (such as montmorillonite (MMT), kaolin, etc.) blended intercalation, the PLA modification has also been studied extensively, after intercalation PLA material mechanical properties, barrier and resistance fuel and other properties are significantly improved.
