Abstract Our previous work reported for the first time that antimony tin oxide (ATO) nanoparticles were prepared by using reduced graphene oxide aerogels (rGOA) three-dimensional network as scaffolds. In this study, we encapsulated the hybrid aerogels as a whole by conducting polyaniline (PANI) to investigate the effect of the introducing of PANI on microstructure and performance of rGOA/ATO-PANI hybrids. Characterization of the as-prepared samples were performed by scanning electron microscopy (SEM), fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray diffraction (XRD), Raman spectroscopy, ultraviolet visible near infrared spectroscopy (UV–VIS–NIR) and compressive stress. The electrochemical performances of hybrids were also investigated as well. The results showed that PANI was successfully grafted on rGOA/ATO and formed a compact film, which could further improve the conductivity of the hybrids and infrared absorption performance. The PANI had crystalline phases, and corresponding diffraction peaks were found in rGOA/ATO-PANI, which further indicated that PANI grafted on the surface of rGOA/ATO. The mechanical, electrochemical, infrared barriering performance of rGOA/ATO-PANI were improved as well.

还原氧化石墨烯气凝胶/氧化锑锡-聚苯胺杂化物的红外阻隔行为

摘要 我们之前的工作首次报道了使用还原氧化石墨烯气凝胶 (rGOA) 三维网络作为支架制备氧化锑锡 (ATO) 纳米颗粒。在这项研究中，我们通过导电聚苯胺 (PANI) 将混合气凝胶整体封装，以研究 PANI 的引入对 rGOA/ATO-PANI 混合体的微观结构和性能的影响。通过扫描电子显微镜 (SEM)、傅里叶变换红外 (FTIR) 光谱、热重分析 (TGA)、X 射线衍射 (XRD)、拉曼光谱、紫外可见近红外光谱 (UV- VIS-NIR）和压应力。还研究了杂化物的电化学性能。结果表明，PANI成功接枝在rGOA/ATO上并形成致密的薄膜，进一步提高了杂化物的导电性和红外吸收性能。PANI具有结晶相，在rGOA/ATO-PANI中发现了相应的衍射峰，进一步表明PANI接枝在rGOA/ATO的表面。rGOA/ATO-PANI 的机械、电化学、红外阻隔性能也得到了改善。
