在甘氨酸存在条件下,经混合金属盐溶液在pH为10．0时共沉淀后的水热反应,可成功合成甘氨酸插层的镁铝双氢氧化物(Gly-LDHHTT)．产物以XRD、IR、TEM／SEM、TG／DTA等技术进行表征．结果表明,120℃水热合成10 h的产物晶型完善,沿a和c方向的晶粒尺寸最大,产物热稳定性好．TEM观察晶粒呈明显的六边形,SEM形貌呈现边缘略有卷曲的团聚薄片．通过进一步探讨甘氨酸插层镁铝双氢氧化物层离的机制后,获得了在室温下实现水热合成产物快速层离的方法,为层离-吸附法成功运用于双氢氧化物／聚合物纳米复合材料制备体系中提供重要的实验基础．
In the presence of glycine, the mixed metal salt solution at pH 10.0 coprecipitation after hydrothermal reaction, glycine intercalation of Mg-Al double hydroxide (Gly-LDHHTT) can be successfully synthesized. The products were characterized by XRD, IR, TEM / SEM, TG / DTA and other techniques. The results showed that the crystal form of the product synthesized by hydrothermal synthesis at 120 ℃ for 10 h was perfect, the grain size along the a and c directions was the largest, and the product had good thermal stability. TEM observation showed a clear hexagonal crystal grains, SEM appearance of the edge of a slightly curly reunion sheet. By further exploring the mechanism of glycine interlayer Mg-Al double hydroxide separation, a method of achieving rapid delamination of the hydrothermal synthesis product at room temperature was obtained and successfully applied to double hydroxide / polymer by delamination-adsorption Nanocomposite preparation system provides an important experimental basis.
