研究了合成温度对Tyr(酪氨酸)/LDH(层状双氢氧化物)纳米复合物性质的影响. 结果表明: 随着合成温度的升高, 纳米复合材料的层间距和比表面积逐渐降低; 随着温度的升高, 合成粒子的形状由球形到三角形最后变为无定形. 进一步的研究表明, 这些规律性的变化与插入层间的生物分子数量有关.

关键词: 层状双氢氧化物, 酪氨酸, 生物分子纳米复合材料

The influence of temperature on the properties of Tyr/LDH nanohybrids has been examined. The results indicate that the basal spacing and specific surface areas decrease with the increase of temperature. Also, the shape of the nanohybrids changes from spheres to triangles last to amorphisms as the increase of temperature. The in-depth study shows that the change is related with the amount of the biomolecules in the interlayers.

Key words: layered double hydroxide, tyrosine, biomolecule nanohybrids
