Multilayer dielectric silver stack: Saint GobainRecent Research Landscape

Oxidation and delamination of reflective silver layers on glass substrates lead to mirror degradation and loss of specular reflectivity. Engineering the dielectric-metal interface and epoxy resin encapsulation stabilizes the stack against environmental corrosion.

What technical problems is Saint Gobain addressing in Multilayer dielectric silver stack?

Silver layer atmospheric corrosion

(3)evidences

Atmospheric exposure and moisture cause chemical degradation and tarnishing of thin-film silver reflectors. Preventing this degradation maintains high specular reflectivity and structural integrity of the mirror stack.

Silver layer oxidative degradation

(1)evidences

Silver thin films are highly susceptible to oxidation, sulfidation, and moisture-induced corrosion. Preventing this degradation maintains the optical transparency and electrical conductivity required for high-performance coatings.
