Atomic Force Microscopy (AFM) and in situ Small Angle X-ray Scattering (SAXS) were used to investigate the evolution of the aluminogermanate imogolite-like nanotubes concentration and morphology during their synthesis. In particular, in situ SAXS allowed quantifying the transformation of protoimogolite into nanotubes. The size distribution of the final nanotubes was also assessed after growth by AFM. A particular attention was focused on the determination of the single and double walled nanotube length distributions. We observed that the two nanotube types do not grow with the same kinetic and that their final length distribution was different. A model of protoimogolites oriented aggregation was constructed to account for the experimental growth kinetic and the length distribution differences.
原子力显微镜（AFM）和原位小角 X 射线散射（SAXS）被用于研究在合成过程中锗铝水滑石类似纳米管浓度和形态的演变。特别是，原位 SAXS 允许定量转化原水滑石成纳米管。生长后，通过 AFM 评估最终纳米管的尺寸分布。特别关注确定单壁和双壁纳米管长度分布。我们观察到，两种类型的纳米管的生长动力学不同，它们的最终长度分布也不同。构建了一个原水滑石定向聚集模型，以解释实验生长动力学和长度分布差异。
