Marie Curie University of Lublin: Biodegradable composites based on polylactic acid and lignin
Polylactic acid (PLA) is a popular biodegradable polyester material, but due to its poor mechanical properties, thermal properties, and poor flame retardant properties, the modification of PLA has always been a research hotspot in academia and industry. . At present, there have been many research works on the use of biomass fillers to strengthen and toughen modified PLA. Among all biomass fillers, lignin is a very potential one. Past studies have shown that adding lignin to PLA can effectively improve the thermal stability, mechanical properties, ductility, and UV resistance of PLA.
Recently, Professor Olena Sevastyanova and her research team from Madame Curie University in Lublin, Poland, used natural lignin and silica to achieve the blending modification of PLA, and studied the prepared PLA-lignin composite material in detail. various properties including flame retardant properties.
