The kinetics for initiation and growth of anodic titania nanotubes is not clear yet, because nanotubes are usually formed rapidly and initiation of nanotube embryos cannot be observed. By decoupling oxide growth and dissolution, nanotube embryos are fabricated beneath a pre-formed compact layer. Based on theories of ionic and electronic current, as well as the oxygen bubble mould effect, a mathematical model is developed for embryo initiation. The model exhibits high fidelity to measured current-time transients. Based on this model, the mechanism of nanotube embryo growth under different thickness of pre-formed layers is quantitatively explained. The embryos initiate without exposure to electrolyte, which is evidence against the traditional field-assisted dissolution theory.

阳极二氧化钛纳米管的引发和生长动力学尚不清楚，因为通常会迅速形成纳米管并且无法观察到纳米管胚胎的引发。通过使氧化物的生长和溶解脱钩，可以在预先形成的致密层下方制造纳米管胚。基于离子电流和电子理论以及氧气气泡霉菌效应，开发了用于胚胎萌发的数学模型。该模型对测量的电流-时间瞬变表现出很高的保真度。基于该模型，定量解释了不同厚度的预成型层中纳米管胚生长的机理。胚胎在不接触电解质的情况下开始萌发，这是反对传统的场辅助溶解理论的证据。
