摘要:	在塗料的世界有各式各樣的種類，其發展的方向不外乎都是源自人類的需求面，因此會誕生出不同的外觀及功能性。常見的導光方式有：材料（玻璃或塑膠）、面鏡或透鏡等，在本研究中的方法為在塗料中加入導磁物質，並通過外加電磁場使其可控制光線的反射，主要目標為掌握磁力線調制微結構的方法。本研究先從涉略可選用添加至塗料中的導磁物質，篩選完畢後設計塗料配方架構，並實際試驗於不同磁鐵形狀、尺寸、摸索不同磁場之磁力線變化（微結構差異）引導出可調制之光形並發現其霧化尺寸變化及比例有所不同（2x1->12x2..等等）。實驗結果顯示用於機車儀表板在鏡射角度20°下與未處理樣品比較，反射光強度最多可減少60%，眩光指數可改善30%，清晰度可改善90%，另外為了確保此應用方法的穩定性及使用時限，設定測試其耐候性，預測產品使用壽命（耐老化）等。最後，此方法預計可以衍伸應用在實現對光的高效控制，包括光的波長、光強度、光分布等方面的調節，應用於顯示技術-提升顯示器的亮度、對比度和色彩性能或者有望拓展光學元件的功能和性能...等與人類生活習習相關的科技，促使人類文明發展進一步在多個領域中產生應用價值。;In the world of coatings, there are various types developed to meet human needs, leading to different appearances and functionalities. Common light-guiding methods include materials (glass or plastic), surface mirrors, or lenses. In this research, we propose a method of incorporating magnetic materials into coatings to control light reflection using an external electromagnetic field. The primary objective is to explore ways to modulate the microstructure through magnetic field manipulation. The study begins with a survey of suitable magnetic materials that can be added to coatings. After screening, a coating formulation is designed. Practical experiments are conducted to observe the magnetic field variations (microstructural differences) by testing different magnet shapes, sizes, and exploring various magnetic field settings. This process yields controllable light patterns with different levels of diffusivity (e.g., 2x1 to 12x2). The experimental results demonstrate that when applied to motorcycle dashboards and compared to untreated samples at a reflection angle of 20°, the reflected light intensity can be reduced by up to 60%, glare index improved by 30%, and clarity enhanced by 90%. Additionally, to ensure the stability and longevity of this application, weather resistance tests and aging predictions are conducted. Ultimately, this method is expected to have broader applications in efficiently controlling light, including adjusting wavelength, intensity, and distribution. It can be employed in display technologies to enhance brightness, contrast, and color performance, or extend the functionality and performance of optical components. These advancements are closely related to human life and can significantly contribute to various technological fields, promoting the further development and practical application of human civilization.
