The global energy consumption in the building sector is enormous annually, and the energy consumed in the building part is mainly used for heating, ventilation, and air conditioning. Smart windows can effectively reduce the energy consumed for heating, ventilation, and air conditioning. Vanadium dioxide (VO2) has been widely used in the preparation of thermochromic smart window films due to its excellent properties, but the low luminous transmittance of VO2-based smart films has been one of the main issues limiting their application. In this paper, we utilized the electrospinning technology to...
