If you floated thousands of square miles of it on the surface of the oceans, yes. But that first assumes a reasonable time payback of the CO2 burden of manufacturing the stuff in the first place, which is not a given. It's obviously not practical for oceans, but it might protect ice caps and glaciers.

Could we cover large portions of the Earth with this material and reverse global warming?
Probably wouldn't be cost-effective, but it'd work in principle.
