摘要:

氫致變色薄膜作為一種新型功能材料，以具有可逆吸放氫特性的復合薄膜為核心，通過氫化和脫氫實現透明態和反射態之間的轉換，對可見及紅外波段光譜都具有智能調控性，因而可被廣泛應用于智能調光節能窗和氫氣傳感器等領域。鎂具有較高的儲氫能力，而且產量豐富，易與多種元素復合，這使得鎂基材料在氫能源方面發揮著越來越重要的作用。鎂基薄膜器件具有結構簡單、響應速度快、光學調控范圍廣和可持續性強等優點，是目前主要的氫致變色功能薄膜材料。本文綜述了氫致變色鎂基薄膜在智能窗和光纖傳感器領域的研發過程、變色原理以及復合體系，同時對研究現狀中存在的各類問題和改性機制進行了簡要分析，并就氫致變色鎂基薄膜材料的發展趨勢進行了展望。

Abstract:

As a new functional material, hydrogen-chromic film is mainly composed of a core composite film with reversible hydrogen storage property. It converts between transparent and reflective states through hydrogenation and dehydrogenation, regulates light at the visible and infrared spectrum intelligently. Therefore, it is widely used in smart switchable energy-saving window and hydrogen sensor. Magnesium has high hydrogen storage capacity and abundant output, then it is easy to be combined with various elements, these characteristics make magnesium-based materials play an important role in hydrogen energy application. The magnesium-based thin film device has the advantages such as simple structure, rapid response, wide optical control range and strong sustainability, it is the main hydrogen-chromic film material currently. This paper reviews the research process of hydrogen-chromic magnesium-based films, including their development, color change principle and composite system in the fields of smart window and optic fiber sensor, meanwhile, the current problems and modification mechanisms during the research status are also been briefly analyzed, then their future developments are prospected.
