Thermal characterization of some multifunctional environmentally friendly materials based on plasticized poly (lactic acid) (PLA)/chitosan (CS) and rosemary extract (R) previously obtained is presented. Differential scanning calorimetry (DSC) associated with other complex investigations such as chemiluminescence and coupled thermogravimetry (TG)/Fourier-transform infrared spectroscopy (FT-IR)/mass spectroscopy (MS) was performed in order to test both the thermal behavior and the biocomposition–property relationship. It was established that the rosemary ethanolic extract offers an efficient protection against thermoxidative degradation to the new developed plasticized PLA-based biocomposites which show good thermal properties, being suitable for both medical and food packaging applications.

基于增塑的PLA,壳聚糖和迷迭香乙醇提取物的一些生物相容性和可降解材料的热行为研究

介绍了一些基于增塑聚乳酸(PLA)/壳聚糖(CS)和迷迭香提取物(R)的多功能环保材料的热特性。进行了差示扫描量热法(DSC)和其他复杂的研究,例如化学发光和耦合热重分析(TG)/傅立叶变换红外光谱(FT-IR)/质谱(MS),以测试热行为和生物成分–财产关系。已经确定,迷迭香乙醇提取物为新开发的增塑的基于PLA的生物复合材料提供了防止热氧化降解的有效保护,该复合材料显示出良好的热性能,适用于医疗和食品包装应用。
