二氧化钒薄膜的商业化：不同界面对劣化过程影响的研究
Towards Commercializing Vanadium Dioxide Films: Investigation of the Impact of Different Interface on the Deterioration Process for Largely Extended Service Life
摘要：
长期稳定性是阻碍基于二氧化钒（VO2）的功能膜商业化的最紧迫的问题，其显示出相对相变性能的逐渐损失，特别是在潮湿条件下用作智能窗时。在这里，我们研究了不同的界面对VO2薄膜的劣化过程的影响，并提出了一种新的封装结构，大大延长了使用寿命。疏水性和稳定的二氧化铪（HfO2）层已被纳入VO2薄膜封装的表面和截面。通过改变HfO2层的厚度和结构，可以有效地抑制VO2的降解过程。所提出的薄膜可以保持稳定的相变性能在高相对湿度（90%）和温度（60摄氏度）超过100天，这相当于约16年的真实环境。提高VO2材料的稳定性是实现长期使用的高性能薄膜商业化生产的必要步骤。
英文摘要：
Long term stability is the most pressing issue that impedes commercialization of Vanadium Dioxide (VO2) based functional films, which show a gradual loss of relative phase transition performance, especially in humid conditions when serving as smart windows. Here, we investigated the impact of different interface on the deterioration process of VO2 films and proposed a novel encapsulation structure for largely extended service life. Hydrophobic and stable hafnium dioxide (HfO2) layers have been incorporated with VO2 films for encapsulated surfaces and cross sections. With modified thickness and structure of HfO2 layers, the degradation process of VO2 can be effectively suppressed. The proposed films can retain stable phase transition performances under high relative humidity (90%) and temperature (60 Celsius) over 100 days, which is equal to about 16 years in the real environment. Improving the stability of VO2 materials is a necessary step towards commercializing production of high performance films for long term use.
