摘要:
通过一步共沉淀法合成三种含镍层状双氢氧化物(NiFe、NiAl和NiCr LDHs),研究这些LDHs化合物的结构、形貌和性能,并用于制备PLA/LDHs纳米复合材料及比较研究复合材料的热性能。TGA结果表明PLA/LDHs复合材料具有较高的残留炭量,DSC结果显示复合材料的玻璃化转变温度没有发生明显变化。SEM显示PLA/NiFe LDH复合材料的炭层最致密,且LRS结果说明其有序化碳的含量最高。TEM图像显示LDHs在PLA基体中均具有良好的分散并且呈现插层和剥离状态。由于三价金属离子的影响,NiFe、NiAl和NiCr LDHs能够不同程度地提高材料残留炭层的质量。
Abstract:
Three different nickel-containing layered double hydroxides(NiFe, NiAl and NiCr LDHs)were synthesized by one-step co-precipitation method. The structure, morphology and property of these LDHs were investigated. They were used to prepare PLA/LDHs nanocomposites. The thermal property of PLA/LDHs composites was researched and compared. TGA results showed that PLA/LDHs composites had higher char residue. DSC suggested that the glass transition temperature of composites had no obvious change. SEM presented that the PLA/NiFe composite char residue was densest, and the largest ratio of the ordered carbon was presented in LRS. TEM images of PLA composites illustrated that all the LDHs had a good dispersion in PLA matrix, and exhibited intercalation or exfoliation. Owing to trivalent cations effect, NiFe, NiAl and NiCr LDHs played different roles in improving the char residue quality of PLA composites.
