It was considered that , the substituted ti reacted with ni3al in - situ and a layer of mo solid solution was formed around the tic particles , which decreased the solid - liquid surface tension between ni3al - tic , leading to the decreasing of wetting angle 掺入mo后置换出的ti与ni _ 3al发生原位反应,在tic颗粒周边形成一个含mo的固溶壳层,降低了ni _ 3al - tic之间的液-固表面张力,导致了接触角的下降。
The hydrophilicity of the modified nano - tio2 film was also studied . the ruslt shows that the hydrophilic angle has a little increase , but its super hydrophilicity is not alterant , and also shows the hydrophilic angle increasing on open entironment is slowing 结果表明,改性后催化剂的接触角有所增加,但催化剂的超亲水性没有发生改变,同时催化剂经等离子体处理后在开放的环境中样品的接触角的变化缓慢一些。
The a - c films were quantitatively analyzed by boxing dimension method . it indicates that with the fractal dimension increase , such surface of a - c film has more complicated microstructure , more and finer nanostructured grooves , so that it is able 随着分形维数的增大,薄膜的表面具有更加复杂的结构,表面有更多和更精细的具有纳米尺度的凹凸、皱褶和缺陷结构,具有更大的吸附和容纳气体的能力,从而提高水滴薄膜表面的接触角。
The uv - vis spectra , contact angle test and afm analysis indicated that all the films so prepared had a layer - by - layer structure . transmission electron microscopy ( tem ) analysis revealed that zno nanoparticles were equally distributed in the composite film 采用紫外一可见光谱wv vis ) 、接触角测试、原子力显微镜( mm )等分析技术对纳米复合湿敏膜进行了表征,发现四个纳米自组装复合膜体系都是层层交替结构, zno纳米粒子均匀分散于有机无机自组装膜中。
