摘要: 
觸控面板表面鍍上抗污(Anti-Smudge;AS)薄膜,是現行觸控面板產品中,愈來愈不可或缺的產品需求,抗污薄膜是藉由在基材表面鍍上一層低表面能的材料,使表面具備疏水、疏油特性,以達到表面抗污、容易清潔等功能,並擁有表面滑順的觸感,讓觸控面板更方便操作。本研究利用低成本之噴霧塗佈技術來製作抗污薄膜,探討不同藥液濃度以及不同烘烤溫度條件下,對抗污薄膜之水接觸角、耐磨耗性、動摩擦係數以及光學特性的影響。
研究結果顯示,改變藥液濃度其水接觸角、耐磨耗性、動摩擦係數皆會隨藥液濃度增加而增加,於藥液濃度0.20%時有較高的水接觸角、耐磨耗性佳及高動摩擦係數,濃度越高愈能使分子團成膜堆積量充足之疏水性抗污薄膜,使之水接觸角大,也使得疏水性抗污薄膜較不易被磨損而脫落,其試片表面因堆積量過多使分子團聚集產生些微白霧現象。
當藥液濃度相同時,改變烘烤溫度,烘烤溫度高於100℃,其水接觸角差異不大,當烘烤溫度大於150℃時,即可提供足夠的能量供疏水性抗污薄膜與玻璃表面鍵結,而使得疏水性抗污薄膜較不易被磨損而脫落,其耐磨耗較佳,摩擦係數及光學特性則不會隨烘烤溫度不同而有所改變。

Coating anti-smudge film on the touch panel has become an important issue in the touch panel usages. Anti-smudge material is coated on the substrate surface by a layer of low surface energy material to create the feature of hydrophobic and oleophobic, in order to reach anti-smudge, easy to clean and smooth to touch for a better touch panel operation.
This research is basis on low cost spray coating method to produce hydrophobic anti-smudge film, and explore the different coating solution concentrations and various temperature conditions in the influence of hydrophobic anti-smudge film’s water contact angle、abrasion resistance、dynamic friction coefficient and optical characteristics.
The results show that the change of the coating solution concentration. Water contact angle, abrasion resistance and dynamic friction coefficient have been influenced with increasing coating concentration. When the solution concentration reach to 0.20 wt% , the coating film possesses higher water contact angle, better abrasion resistance and higher dynamic friction coefficient. Higher concentration can make molecules stacked enough to get higher water contact angle and better abrasion resistance. But surface of the test piece results in slight mist aggregation phenomena due to excessive accumulation of the molecules .
Keep a same solution concentration and change the oven temperature. When the oven temperature is higher than 150℃. It can provide enough energy for a hydrophobic anti-smudge film bonding to the glass surface. The strong bonding results in the hydrophobic anti-smudge film to possess a good abrasion resistance that is less likely to wear off. The dynamic friction coefficient and optical properties do not vary with the change of the oven temperature.
