摘要

摘要采用溶液插层法制备了镁铝层状双氧根修饰淀粉生物纳米复合材料(淀粉/层状双氧根)。利用傅里叶变换红外光谱、x射线衍射和高分辨率透射电子显微镜技术对生物纳米复合材料进行了系统的表征。淀粉的热稳定性由于层状双氢氧化物在淀粉基体内的分散而增强。淀粉基质中层状双氢氧化物的脱层使淀粉的耐化学性得到了很大的提高，但生物降解性能稍有降低。在此，层状双氢氧化物作为潜在的层压填料改变淀粉的结构、耐热性和耐化学性，而几乎不牺牲生物降解行为。图形抽象

Delamination of Mg-Al Layered Double Hydroxide on Starch: Change in Structural and Thermal Properties

ABSTRACT Mg-Al layered double hydroxide decorated starch bionanocomposites (starch/layered double hydroxide) are prepared by solution intercalation method. The bionanocomposites are systematically characterized by Fourier transform infrared spectroscopy, X-ray diffraction, and high-resolution transmission electron microscopy techniques. The thermal stability of starch is enhanced due to dispersion of layered double hydroxide within the starch matrix. The chemical resistance property of starch is improved substantially with slight sacrifice in biodegradation behavior by the delamination of layered double hydroxide in starch matrix. Herein, layered double hydroxide acts as potential laminated filler for change in structural, thermal, and chemical resistance properties of starch with little sacrifice in biodegradable behavior.
