Shan X., Lo, S.M., Tai Q., Gui Z., Hu, Y. and Jiang S., 2014. Effect of Nickel-containing Ligand on Thermal Stability and Combustible Property of Poly(lactic acid). Fire Safety Science 11: 874-882. 10.3801/IAFSS.FSS.11-874
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.
