200907522 九、發明說明： 【發明所屬之技術領域】 本發明之目的係為提供一種電致色變結構及其製 造方法，特別是透過一種其電致色變層中具有複數個 互相接觸之導電奈米粒子，該導電奈米粒子層具有透 光性，且該些導電奈米粒子表面包覆著電致色變材 料，藉以增加著色、去色之反應速率及循環壽命的電 致色變結構與其製造方法者。 【先前技術】 電致色變（electrochromic)的概念已於1961提 出，其主要係利用「電致色變物質在受到外加電場的 作用之下，將會改變其對光的吸收能力，而導致顏色 及光穿透度的變化，且具有可逆及持續的特性」。即對 電致色變材料施予外加電位時，其顏色會改變。例如， 當電致色變結構被施予一可見光，實質上電致色變結 構會吸收某特定波長之光穿透，藉此，以防止過度的 光線穿過電致色變結構，可用以調節不同波長光之入 射量。傳統之電致色變結構包含一第一透明導電基 材、一電致色變層、一電解質層及一第二透明導電基 材，第一透明導電基材及第二透明導電基材位於電致 色變結構的最外側，電解質層與電致色變層則係配置 於第一透明導電基材及第二透明導電基材間，當在第 一透明導電基材及第二透明導電基材間施予一預設電 位差，便可使電致色變結構改變顏色，達成所預設之 光學特性。 200907522 典型的第一透明導電基材及第二透明導電基材係 由玻璃及在玻璃上設導電薄膜而成，但是在一些特殊 的應用上亦有利用在塑膠材料上設導電薄膜作為透明 導電基材者。電致色變層可以有機化合物實現，如紫 精【Vi〇l〇gen】或吡啶【Pyrodine】，或是以無機化合 物來實現，例如無機過渡金屬化合物氧化鶴【恥3】、 氧化鉬【M0O3】或五氧化二飢【VA5】。另一方面，電 解質層可用一已添加鋰氣化物及高氯酸鹽之溶液。根 據不同的光學特性，電致色變結構可應用作為調節室 内陽光入射能量之智慧型窗戶（Smart windows)、汽車 的反強光照後鏡（Anti-dazzling Rear view Mirrors)、車内的天窗（Sun Roofs)、靜態圖案看板或 數子顯示器（Static display Devices)等等。 請參閱第一圖所示，其係顯示現有電致色變結構 之示意圖，該現有的電致色變結構係為呈薄膜式結 構’其包含一第一透明導電基材（11)、一電致色變層 (12)、一電解質層（13)、一絕緣層（14)及一第二透明 導電基材（15)，該電致色變層（12)及電解質層（13)介 於第一及第二透明導電基材（11)、（15)中間，並在周 圍以絕緣層（14)予以封裝；又，由於著色與去色反應 速度與離子擴散進入電致色變層（丨2)的速率有關，當 電致色變層（12)之厚度越厚離子要擴散至整個電致色 變層（12)之時間就越長；反之，電致色變層（12)越薄， 則離子可快速擴散至整個電致色變層（12)，但卻會影 響顏色的對比度。今，現有之薄膜式電致色變結構由 200907522 於其本身結構上的限制使其反應面積受限而影響反應 速率，若為了提升反應速率而減低電致色變層（12)厚 度，卻會使顏色的對比度降低，以致造成實務應用上 的諸多不便。 【發明内容】 今，發明人即是鑒於現有之電致色變結構無法滿 足業界對其反應速率及顏色對比度的需求，於是本發 明人基於多年從事研究與諸多實務經驗，經多方研究 設計與專題探討，遂於本發明提出一種電致色變結構 及其製造方法，以作為前述期望之實現方式與依據。 本發明之目的為提供一種電致色變結構及其製造 方法，尤其是指一種在電致色變層中設複數個互相接 觸之導電奈米粒子，該導電奈米粒子層具有透光性， 且每一導電奈米粒子表面係包覆一電致色變材料，以 增加其著色、去色之反應速率者。 而本發明之目的、功效是由以下之技術所達成： 其包含一第一透明導電基材、一第二透明、不透 明或反射式導電基材、一第一電致色變層及一電解質 層；第一透明導電基材、第二導電基材係位於電致色 變結構的二側，並令第一電致色變層及電解質層位處 於第一透明導電基材與第二透明、不透明或反射式導 電基材之間，該第一電致色變層係包含複數個互相接 觸之導電奈米粒子，且每一導電奈米粒子表面係包覆 一電致色變材料，此外該導電奈米粒子層具有透光 性，當第一透明導電基材及第二導電基材間被施予一 8 200907522 預設電位差時，電解質層中之離子將會遷入或遷出電 致色變層，並據此改變電致色變層中電致色變材料之 光學特性，使該電致色變結構之顏色因此產生著色或 去色之變化。 承上所述，因本發明之電致色變結構之第一電致 色變層係包含複數個互相接觸之導電奈米粒子，且每 一導電奈米粒子表面係包覆一電致色變材料，而使電 致色變層成為多孔隙之薄膜結構，藉由該多孔隙結構 增加電致色變層有效參與變色反應之面積，而達到提 升顏色對比與加速變色反應速率的效果，有效解決現 有薄膜式電致色變結構之缺點，且加入導電奈米粒子 後，可強化整體電致色變結構，大幅提升結構之耐用 性。 茲為使貴審查委員對本發明之技術特徵及所達 成之功效有更進一步之暸解與認識，下文僅提供較佳 之實施例及相關圖式以為輔佐之用，並以詳細之說明 文字配合說明如後。 【實施方式】 以下將參照相關圖式，說明本發明較佳實施例之 電致色變結構及其製造方法，其中相同的元件將以相 同的參照符號加以說明。 請參閱第二圖，係顯示本發明之電致色變結構之 構造示意圖，其包含一第一透明導電基材（21)、一第 二導電基材（22)〔可為透明、不透明或反射式〕、一第 一電致色變層（23)及一電解質層（24)。 9 200907522 該第一透明導電基材（21)，係由玻螭或塑膠材料製 成，並於其第一端面（211)上設有導電薄膜（212)〔可 為透明導電薄膜〕； 該第二導電基材（22)〔可為透明、不透明或反射 式〕’其第一端面（221)上同樣設有導電薄膜（222);

Description of the Invention: [Technical Field] The present invention aims to provide an electrochromic structure and a method for fabricating the same, in particular, through a plurality of electrically conductive layers having mutual contact with each other in an electrochromic layer a rice particle having a light transmissive property, and the surface of the conductive nanoparticle is coated with an electrochromic material, thereby increasing an electrochromic structure of a coloring, decoloring reaction rate and a cycle life thereof Manufacturing method. [Prior Art] The concept of electrochromic has been proposed in 1961. It mainly uses "electrochromic substances to change their ability to absorb light under the action of an applied electric field, resulting in color." And changes in light penetration, and have reversible and continuous characteristics." That is, when an applied potential is applied to the electrochromic material, the color thereof changes. For example, when an electrochromic structure is applied to a visible light, a substantially electrically discolored structure absorbs light of a particular wavelength, thereby preventing excessive light from passing through the electrochromic structure, which can be used to adjust The amount of light incident at different wavelengths. The conventional electrochromic structure comprises a first transparent conductive substrate, an electrochromic layer, an electrolyte layer and a second transparent conductive substrate, wherein the first transparent conductive substrate and the second transparent conductive substrate are electrically The outermost side of the color-changing structure, the electrolyte layer and the electrochromic layer are disposed between the first transparent conductive substrate and the second transparent conductive substrate, when the first transparent conductive substrate and the second transparent conductive substrate By applying a predetermined potential difference, the electrochromic structure can be changed in color to achieve the predetermined optical characteristics. 200907522 The typical first transparent conductive substrate and the second transparent conductive substrate are made of glass and a conductive film on the glass, but in some special applications, a conductive film is also provided on the plastic material as a transparent conductive base. Material. The electrochromic layer can be realized by an organic compound, such as viologen [Vi〇l〇gen] or pyridine [Pyrodine], or by an inorganic compound, such as an inorganic transition metal compound oxidized crane [Shame 3], molybdenum oxide [M0O3] 】 or pentoxide hunger [VA5]. Alternatively, the electrolyte layer may be a solution in which lithium gasification and perchlorate have been added. Depending on the optical properties, the electrochromic structure can be applied as a smart window for adjusting indoor solar incident energy, anti-dazzling Rear view Mirrors, and sun roofs in the car. ), static pattern board or static display devices, and so on. Referring to the first figure, which is a schematic diagram showing an existing electrochromic structure, the conventional electrochromic structure is in a film structure, which comprises a first transparent conductive substrate (11), an electric a color changing layer (12), an electrolyte layer (13), an insulating layer (14) and a second transparent conductive substrate (15), the electrochromic layer (12) and the electrolyte layer (13) are interposed The first and second transparent conductive substrates (11), (15) are interposed and surrounded by an insulating layer (14); and, due to the coloring and decoloring reaction speed and ion diffusion into the electrochromic layer (丨2) The rate is related. The thicker the thickness of the electrochromic layer (12), the longer the ion will diffuse to the entire electrochromic layer (12); on the contrary, the thinner the electrochromic layer (12) , the ions can quickly diffuse to the entire electrochromic layer (12), but it will affect the contrast of the color. Nowadays, the existing film-type electrochromic structure is limited by its structure in 200907522, which limits the reaction area and affects the reaction rate. If the thickness of the electrochromic layer (12) is reduced in order to increase the reaction rate, The contrast of the color is lowered, resulting in inconvenience in practical applications. SUMMARY OF THE INVENTION Now, the inventor is in view of the fact that the existing electrochromic structure cannot meet the industry's demand for its reaction rate and color contrast, so the inventor has been engaged in research and many practical experiences for many years, and has been researched and designed by many parties. In view of the above, an electrochromic structure and a method for fabricating the same are proposed as the implementation and basis of the foregoing.

When a predetermined potential difference between the first transparent conductive substrate and the second conductive substrate is applied, the ions in the electrolyte layer will move into or out of the electrochromic change. The layer, and thereby changing the optical properties of the electrochromic material in the electrochromic layer, such that the color of the electrochromic structure causes a change in coloration or discoloration. According to the above, the first electrochromic layer of the electrochromic structure of the present invention comprises a plurality of conductive nano-particles in contact with each other, and each of the surface of the conductive nano-particles is coated with an electrochromic change. The material, and the electrochromic layer becomes a porous film structure, and the porous structure increases the area of the electrochromic layer to effectively participate in the color change reaction, thereby achieving the effect of improving the color contrast and accelerating the color change reaction rate, and effectively solving the problem. The shortcomings of the existing thin film electrochromic structure, and the addition of conductive nano particles, can strengthen the overall electrochromic structure and greatly improve the durability of the structure.
