Thermochromic VO2 has garnered widespread attention with unique optical regulation in the fields of smart windows. However, windows persistent stability and tunability an outdoor environment are still a challenge. This study presents multifunctional film, including thermochromic VO2/polymer layer particles dispersed urea-polydimethylsiloxane (uPDMS) matrix smooth liquid-infused porous surface (SLIPS) silicone oil filling structures. Entrapping within net ensures stability. The extensive hydrogen bonds between urea groups highly mobile polydimethylsiloxane chains ensure self-healing performance, while upper SLIPS offers self-cleaning performance. bilayer composite film demonstrates excellent solar modulation ability (ΔTsol = 20.25%), adequate visible light transmittance (Tlum,c 47.78%), remarkable performance (RA 8.9°), notable abilities (healing rate 88.48%). research herein reliable approach for fabricating stable energy-saving window films.
