Abstract
An anti-fog glass includes a glass body configured as a single layer or a multilayer stack; an active anti-fog layer disposed on the glass body and heating up when being provided with power; and a passive anti-fog layer disposed on the glass body and inhibiting fog from forming on the passive anti-fog layer. The passive anti-fog layer is a super hydrophobic coating and/or hydrophilic coating. Both the active anti-fog layer and the passive anti-fog layer are simultaneously disposed on the glass body to inhibit fog from forming. In this way, in a region of the glass body not covered by the active anti-fog layer, the anti-fog function is achieved by the passive anti-fog layer to a certain degree; in addition, in a region where the passive anti-fog layer itself cannot provide a desired anti-fog level, the active anti-fog layer together with the passive anti-fog layer provide a better anti-fog effect.
