感光變色表面著色技術應用於行動通訊產品之研究

Abstract

本研究之目的是將感光變色技術與表面著色技術結合並應用於行動通訊產品的塑膠機殼外觀著色上，使其行動通訊產品的機殼因照射紫外光線而產生表面色澤變化的效果。實驗將以目前生產行動通訊產品機殼表面著色製程為標準實驗流程，研究過程中除感光變色技術與表面著色技術的結合外，其品質要求需符合行動通訊產品品質的檢驗規範。 實驗結果顯示感光變色原料不易溶解於任何溶劑內，除溶劑的選擇極為關鍵外，溶解過程中亦需配合長時間攪拌。 影響其表面色澤變化效果除表面著色的膜厚外，紫外線的強弱亦會影響其表面色澤的變化效果，表面著色膜厚或紫外線光源強度增加，則其表面色澤變化越深、越快；反之表面著色膜厚越薄、紫外線越弱，則其表面色澤變化越淺、越慢。

The purpose of this study is to combine and apply the photochrmic technique and the surface treatment technique on the plastic shell of the mobile telephone, and explore the effect on varieties shades of color when the shell is exposed to the ultravolet rays. The process of the experiment uses the commercial coating process of mobile telephone as the standard experimentation process, besides combining the photochromic technique with the surface treatment technique, the quality of final product also need tocomply with the inspect standard of the mobile telephone.

Experimental results reveal that the photochromic material doesn't dissolve easily in all solvent, it needs to stir the solution for a long duration to make sure all the photochromic material are totally mixed. The influence of the photofading depends not only on the thickness of the coating, but also the intensity of the ultraviolet rays. If the coating is thicker, the reaction will faster; or if the intensity of the ultraviolet rays are stronger, the reaction becomes more faster.
