This is the first report of the dependence of the pore diameter in a titania membrane prepared by anodizing a titanium substrate in the presence of fluoride ions on the curvature of its surface. Titania membranes with uniform pores are formed on the smooth electrode surface. The pore diameter is greater in the case of negative curvature of the titanium substrate, while it is smaller in the case of positive curvature.

钛基材表面对氟离子存在下阳极氧化形成的氧化钛膜孔径的影响

这是关于通过在存在氟离子的情况下对钛基材进行阳极氧化制备的二氧化钛膜中孔径与其表面曲率的相关性的第一份报告。在光滑的电极表面形成具有均匀孔隙的二氧化钛膜。钛基体在负曲率的情况下孔径较大，而在正曲率的情况下孔径较小。
