摘要

鉴定了红球菌Au-1、假单胞菌PS-17、葡萄酒固氮菌N-15和聚羟基丁酸酯/聚乳酸酯混合物的聚羟基烷酸酯的热性能和物理力学性能。用聚乳酸改性聚羟基丁酸可以改善物理和机械特性，如耐热性、刚性和脆性。混合物中聚乳酸含量的增加导致样品的热稳定性降低和相对伸长率增加。聚羟基丁酸酯/聚乳酸混合物被推荐作为食品、农产品和医药产品的包装材料。

Thermal and physico-mechanical properties of biodegradable materials based on polyhydroxyalkanoates

Thermal and physico-mechanical properties of polyhydroxyalkanoates of Rhodococcus erythropolis Au-1, Pseudomonas sp. PS-17, Azotobacter vinelandii N-15 and polyhydroxybutyrate/polylactide mixtures were identified. Modifying polyhydroxybutyrate with polylactide improves physical and mechanical characteristics such as heat resistance, rigidity, and brittleness. An increase in the content of polylactide in mixtures leads to a decrease in the thermal stability of the samples and an increase in relative elongation. Polyhydroxybutyrate/ polylactide mixtures are recommended as packaging materials for food, agricultural, and pharmaceutical products.
