Would we ever be able to use a material like this to reflect a significant enough portion of the light falling on Earth to reduce the total heat imparted by sunlight in a meaningful way? Could we use this as defacto ice caps to perhaps reduce global temperatures in any real way?

Probably yeah, but more likely it would have to be atmospheric and not surface based. When Mount Pinatubo erupted in 1991 it was estimated that the global temp dropped about 0.5 degrees C over the ensuing year due to the ash cloud blocking the sun

So the actual solution to climate change is to light everything on fire so the smoke cover cools down earth
