Abstract

Nickel-containing ligand (L.) decorated with molybdenum and 1h-pyrazole template was prepared by the hydrothermal method. Then it was added in poly(lactic acid) (PLA) matrix. One goal of this work was to investigate the effect of L. on thermal stability and combustible property of PLA matrix. The structure and property of L. were characterized by fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA). The thermal properties of composites were tested by TGA, differential scanning calorimetry (DSC) and real time fourier transform infrared (RTIR). Combustible properties were researched by microscale combustion calorimetry (MCC). The volatilized products after the sample pyrolysis were also discussed. The thermal stability and combustible property analyses indicated that L. had positive effect in PLA matrix. Dynamic mechanical analysis (DMA) was used to measure the mechanical strength of PLA composites.
含镍配体对聚乳酸热稳定性和可燃性的影响
采用水热法制备了钼和1h-吡唑模板修饰的含镍配体。然后将其加入到聚乳酸(PLA)基体中。本研究的目的之一是研究L.对聚乳酸基体热稳定性和可燃性的影响。利用傅里叶红外(FTIR)、x射线光电子能谱(XPS)和热重分析(TGA)对L.的结构和性质进行了表征。采用热重分析(TGA)、差示扫描量热法(DSC)和实时傅立叶变换红外(RTIR)测试了复合材料的热性能。采用微尺度燃烧量热法(MCC)研究了其可燃性能。并对样品热解后的挥发产物进行了讨论。热稳定性和可燃性分析表明,L.在PLA基质中有积极的作用。采用动态力学分析(DMA)对PLA复合材料的力学强度进行了测试。
