建立防指纹( Anti-fingerprint,AF)涂层实验室评价方法是研制开发手机屏和手机膜 AF涂层的基础。文中提出了通过测定水在手机膜表面的接触角反映汗液中主要成分水在手机膜表面的润湿程度,并通过绘制润湿性包络图表征汗液中其他成分在手机膜表面的润湿程度来研究液体在固体表面的润湿性与固体表面能的关系。在此基础上,设计了一种基于 Young-Laplace方程拟合分析蒸馏水和二碘甲烷在手机膜表面的接触角,利用 Owens-Wendt-Kaelble公式得出被测样品的表面能参数,绘制润湿性包络图并采用面积法求取包络图面积 S,评价表面被液体润湿能力的方法。结合水在手机膜表面的接触角数值,综合分析手机膜的防指纹效果。通过实验分析了 3种手机膜的防指纹效果,结果表明所设计的评价方法能够合理地反映手机膜的防指纹效果。
The establishment of anti-fingerprint lab evaluation method is the basis ofdevelopment of mobile cellphone screen and cellphone film.In this paper,the water contact angle on the surface of mobile phone membrane was measured to indicate the wettability of themain component of sweat on the surface of mobile phone membrane.The relationship betweenthe wettability of liquid on solid surface and the surface energy of solid was studied by drawingthe wettability envelope diagram,which was used to characterize the wettability of othercomponents in sweat on the surface of mobile phone membrane.On this basis,a method based on Young-Laplace equation was designed to fit and analyze the contact angle of distilled water anddiiodomethane on the surface of mobile phone membrane.The surface energy parameters of thetested samples were obtained by Owens-Wendt-Kaelble formula.Then the wettability envelopewas drawn,whose area S could be calculated by area method in order to evaluate the wettability of liquid on the solid surface.Combined with the water contact angle on the surface of mobilephone membrane,the anti-fingerprint effect of mobile phone membrane was analyzedcomprehensively. The anti-fingerprint effect of three kinds of mobile phone membranes wasanalyzed through experiments.The results showed that the evaluation method designed couldreasonably reflect the anti-fingerprint performance of mobile phone membranes.
