Poly(tetrafluoroethylene) (Teflon) has been selected as the self-template structural material in preparation of VO2 films using a reactive magnetron sputtering method and post-annealing process. with spontaneous random nanoporous structures growing on quartz glasses have deliberately established via bottom-up processing through this novel facile approach. The exhibit an excellent optical performance based localized surface plasmon resonance, ultrahigh luminous transmittance (Tlum-L) up to 78.0% promoted solar modulation ability (ΔTsol) 14.1%. Meanwhile, ingenious microstructure film provides antireflection function from multiple perspectives visible light indicates potential windshield vehicles for smart modulation. expand practical application thermochromic fire-new field, breaking envelope single-layer dense away, offering universal prepare homogeneous thin films.
