技術說明

本專利為「以電泳法沉積甲殼素開發多功能智慧窗」，目標應用一是以低耗能之電致變色來降低空調或照明用電；目標應用二是將電致變色智慧窗作為浴室建材，不僅提供浴室最基本之隱私性需求，亦可依照變色時間之長短，對室內需照護之使用者達到即時監控之功能，且不對一般使用者造成困擾。 本專利所提出之電致變色方法優點包括：高控制性、反應速度快及驅動電壓低等優點，且本專利之結構能將其製程與操控簡單化，加上利用甲殼素為變色主要成分，較現有已知電致變色方式更具備兩項新穎性：一是材料環保且對人體無害，甲殼素易被分解而屬綠色環保材料；二是提出之電致變色結構簡單，可取代現有複雜且多層結構。 Our patent, “Development of multi-functional smart window using electrophoretic deposition of chitosan”, has two objects. One is to reduce the cost for indoor illumination and air-conditioning during a hot sunny day. The other is to employ the window in a shower room for the elders or handicapped. The time duration of opaqueness can be controlled to not only keep the privacy but to provide convenience for attendants or nurse. Advantages of proposed smart window include: high flexibility, prompt responses, add low driving voltage. Moreover, the proposed set-up has been simplified. The major component employed has been switched to chitosan. As a result, our proposed window is superior other currently-known windows in material section and window composition. The material is non-toxic and environment-friendly. The layer of window composition is five, less than other commercial products. Cost for maintenance and fabrication can thus be saved.
