选用典型的二氧化钛纳米超亲水薄膜 ,用扫描探针显微镜 (SPM )和电化学测试系统进行一般性的表征 .着重运用固体化学和纳米力学的原理 ,对SPM图像、氧空位浓度和超亲水性的机理进行理论分析 ;进一步解释了作者于 1999年底提出的 ,与润湿性能有关的二氧化钛缺陷生成反应方程、普适表面物理模型、两憎 (amphiphobic)表面概念和材料表面设计问题
A typical nanostructured titania super hydrophilic film was chosen for general characterization employing a Scanning Probe Microscope(SPM)and an electrochemical measurement system.Following from the principles of the solid state chemistry and nanomechanics,intensive theoretical. analyses on the SPM images,the oxygen vacancy concentrations and the mechanism of the super hydrophilicity were made;further illuminations on a reaction equation of titania defect formation,a tentative universal surface physical mode for the wet ability,a concept,amphiphobicity,and surface design were carried out after the author's previous introduction and proposal in the end of 1999.
