Impact of Annealing on the Melt Recrystallization of a-PDLA/α-PLLA Double-layered Films

引用

Chinese Journal of Polymer Science 2024年第2期42卷 230-238,I0009页

Poly(lactic acid)(PLA) as a bio-based polymer with biodegradability and biocompatibility has attracted much attention. To manipulate its properties for different applications, regulation of crystal structure and crystalline morphology becomes an attractive research topic. In this work, the structure evolution of layered samples containing an amorphous poly(D-lactide)(PDLA) layer and a crystalline poly(L-lactide)(PLLA)layer with highly oriented edge-on α lamellar crystals after annealing at 150 ℃ or/and after melt-recrystallization has been studied by AFM, FTIR,and TEM combined with electron diffraction. The results demonstrate that melt recrystallization of the as-prepared sample leads to the formation of abundant randomly oriented PLA stereo-complex(PLA SC) crystals. Annealing at 150 ℃ results in the formation of a small amount of oriented PLA SC crystals at the interface. These PLA SC crystals show great impact on the recrystallization behavior of sample after melting at 190 ℃ and then crystallizing at 90 ℃. First, they impede the mutual diffusion of the overlying PDLA and underlying PLLA, and thus reduce their stereocomplexation ability as manifested by the decreased amount of PLA SC crystals. Second, they act as substrate to initiate the epitaxial crystallization of the overlying PDLA and underlying PLLA, which ensures the production of a highly oriented structure of PDLA and PLLA after melt recrystallization again.

采集规模化养殖园区不同土地利用类型的土壤,采用高效液相色谱仪检测土壤中抗生素的含量,分析抗生素与土壤理化性质之间的关系,并利用风险商值法对养殖场园区土壤中的抗生素进行生态风险评价.结果表明,养殖场周边土壤受到不同程度的抗生素污染,其中检出率和含量平均值最高的是四环素(TC);不同土地利用类型的土壤中,ω(抗生素)平均值大小排序为:玉米地(1.48μg·kg^(-1))>养殖场围栏外0.5 m处(1.27μg·kg^(-1))>山药地(1.03μg·kg^(-1))>牧草地(0.69μg·kg^(-1))>林地(0.18μg·kg^(-1));冗余分析结果显示,全氮、全磷和纤维素酶对土壤样品中抗生素的含量影响较大.根据生态风险评价结果可知,土霉素(OTC)、金霉素(CTC)、强力霉素(DOC)、环丙沙星(CIP)和四环素(TC)属于低风险等级,磺胺嘧啶(SD)和磺胺二甲嘧啶(SM2)为中高风险,应当重视对养殖场周边土壤抗生素污染管控,加强兽用抗生素的管理.
