Dual-phase transformation has been developed as a template-free surface patterning technique in this study. Ordered VO honeycomb structures with a complex hierarchy have been fabricated via this method, and the microstructures of the obtained VO(M) coatings are tunable by tailoring the pertinent variables. The VO(M) honeycomb-structured coatings have excellent visible light transmittance at 700 nm (T) up to 95.4% with decent solar modulating ability (ΔT) of 5.5%, creating the potential as ultratransparent smart solar modulating coatings. Its excellent performance has been confirmed by a proof-of-principle demonstration. The dual-phase transformation technique has dramatically simplified the conventional colloidal lithography technique as a scalable surface patterning technique for achieving high-performance metal oxide coatings with diverse applications, such as catalysis, sensing, optics, electronics, and superwettable materials.
本研究开发了一种双相转变模板自由表面图案化技术。通过该方法制备了具有复杂层次结构的有序 VO 蜂窝结构，并且可以通过调整相关变量来调节所获得的 VO（M）涂层的微结构。VO（M）蜂窝结构涂层在 700nm（T）处具有高达 95.4%的优异可见光透过率和 5.5%的良好太阳能调节能力（ΔT），有望成为超透明智能太阳能调节涂层。通过原理验证证明了其优异的性能。双相转变技术极大地简化了传统的胶体光刻技术，作为一种可扩展的表面图案化技术，用于实现具有多种应用的高性能金属氧化物涂层，如催化、传感、光学、电子和超润湿材料。
