Better safety glasses, if the stuff can be made transparent.
Unbreakable store windows. BLM will not like that.
It would be amazing for the outer skin on the cockpit of an aircraft, if it meets the tensile and thermal requirements...imagine no heavy glass at all, just a complete 360 degrees of transparent fuselage.
if it is truly two dimensional then it has no depth to it at all, so I would guess that it is transparent
