The new ternary (Mg–Zn–Al–) layered double hydroxide (LDH) with an organic modifier-containing azo group (LDH–SHDBS) as a guest anion was prepared by a co-precipitation through one-step synthetic method. The novel electroactive polyamide (EPA) was successfully prepared by direct polycondensation reaction of azelaic acid with a new synthetic diamine 4. The structure of diamine 4 was confirmed by FTIR and ¹H NMR spectra. Also, polyamide/ternary LDH nanocomposites were prepared by resulting EPA and modified ternary LDH under ambient condition. The resulting data using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD) showed ternary LDH were successfully distributed into the EPA matrix. Thermal behavior of the EPA and its nanocomposites were studied by thermogravimetric analysis (TGA) and derivative thermogravimetry (DTG). The presence of LDH layers into EPA matrix improved thermal stability (T₅, T₁₀, char yield) in both air and nitrogen atmospheres. Also, photoisomerization and electrochemical behaviors of EPA and resulting nanocomposites were measured using UV–Vis spectroscopy and cyclic voltammetry (CV), respectively. The UV–Vis spectrum of the obtained nanocomposites showed two peaks at λ_max = 422 and 480 nm related to π–π^∗ and n–π^∗ transitions of trans azobenzene. Moreover, trans to cis isomerization of azomoieties was studied by irradiation of the nanocomposites under 254 nm photons. The CV pattern of EPA exhibited a reversible anodic peak around 0.84 V, corresponding to the nitrogen atom of triphenylamine unit into polymer backbone that improved by incorporation of LDH–SHDBS into EPA matrix.

在其骨架中包含三苯胺部分的新型电活性和光敏聚酰胺/ LDH三元纳米复合材料：合成与表征

通过一步沉淀法通过共沉淀法制备了具有有机改性剂的偶氮基团（LDH-SHDBS）作为客体阴离子的新型三元（Mg-Zn-Al-）层状双氢氧化物（LDH）。通过壬二酸与新型合成二胺4的直接缩聚反应，成功制备了新型电活性聚酰胺（EPA）。FTIR和¹证实了二胺4的结构1 H NMR谱。而且，通过在环境条件下得到的EPA和改性的三元LDH来制备聚酰胺/三元LDH纳米复合材料。使用扫描电子显微镜（SEM），能量色散X射线光谱（EDS）和X射线衍射（XRD）得出的数据表明，三元LDH已成功分配到EPA基质中。通过热重分析（TGA）和衍生热重分析（DTG）研究了EPA及其纳米复合材料的热行为。EPA基质中LDH层的存在改善了热稳定性（T ₅，T ₁₀，焦炭收率）。此外，分别使用UV-Vis光谱法和循环伏安法（CV）测量了EPA和所得纳米复合材料的光致异构化和电化学行为。所得到的纳米复合材料的UV-Vis光谱显示两个峰在λ_最大 相关= 422和480nm的π - π ^*和ñ - π ^*的转变反式偶氮苯。此外，反式至顺式通过在254 nm光子下辐照纳米复合材料研究了偶氮基的异构化。EPA的CV模式在0.84 V附近表现出可逆的阳极峰，对应于聚合物主链中的三苯胺单元的氮原子，通过将LDH–SHDBS掺入EPA基质而得到改善。
