However, the higher durability of hydrophilicity of TiO2,X films compared with pure TiO2 films may be due to a great stability of hydrophilicity site Ti-OH, which is caused by the strong binding action (hydron bond) between Ti-X and Ti-OH.

• 分析认为；卤素离子对TiO2薄膜光致亲水性的影响与其给电子或捕获光致电子作用有关；并提出了其作用模型；而卤素离子与亲水基团(羟基)的氢键作用是使KX-TiO2薄膜能够延长亲水性时间的原因.
