通过化学和热处理对含P的微弧氧化tio2基（TOB）薄膜表面进行修饰，制备出含Na、Ti和O元素的纳米级化合物。在TOB薄膜中，锐钛矿和金红石纳米晶在p掺杂基体中随机分布。在化学处理后的TOB （C-TOB）薄膜表面，含Na的无定形氧化钛呈现纳米级带状形貌。Na、Ti和O在C-TOB薄膜外层沿表面深度分布均匀。化学处理对TOB膜表面粗糙度无明显影响；然而，它改善了它的亲水性。热处理对C-TOB膜外层的Ti、Na和O的化学状态以及润湿能力、元素组成和原子浓度没有影响。然而，热处理后C-TOB膜的相组成和表面形貌与热处理温度有关。
Chemical-and heat treatment was performed to modify the surface of the microarc oxidized TiO2-based (TOB) film containing P to produce nano-scale compounds containing Na, Ti and O elements. In the TOB film, anatase and rutile nanocrystals were randomly distributed in P-doped matrix. On the surface of the chemically treated TOB (C-TOB) film, amorphous titanium oxide containing Na shows nano-scale ribbonlike morphology. Na, Ti and O show uniform distribution in the outer layer of the C-TOB film along surface depth. Chemical treatment did not alter the surface roughness of the TOB film obviously; however, it improved its hydrophilic property. Heat treatment has no influence on the chemical states of Ti, Na and O, as well as wetting ability, elemental composition and atomic concentration in the outer layer of the C-TOB film. However, the phase compositions and surface morphology of the C-TOB film after heat treatment are dependent on the heat treatment temperature.
