红外成像研究PLLA/N-CQDs复合薄膜的结晶性能

Crystallization of PLLA/N-CQDs Composite Films by FTIR Mapping

将水热法制得的氮掺杂碳量子点(N-CQDs)加入聚乳酸(PLLA)基质中,以溶剂浇铸法制备了PLLA/N-CQDs复合薄膜,并通过红外成像分析了N-CQDs的加入对PLLA结晶性能的影响。结果显示,加入N-CQDs可以显著提高PLLA的结晶性能。

In this work,a series of PLLA/N-CQDs composite films were prepared by solvent casting via adding nitrogen-doped carbon quantum dots(N-CQDs),which were synthesized by hydrothermal method,into poly(L-lactic acid)(PLLA)matrix.The effects of N-CQDs on the crystallization behavior of PLLA were analyzed by FTIR mapping.The results show that N-CQDs can greatly improve the crystallization performance of PLLA.
