Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 May 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 September 2028.

Abstract

The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase II project is in commercializing a new, "infinitely" re-polymerizable material called Engineered Circular Adaptive Networks (ECANs). This technology allows chemically recalcitrant plastics—specifically thermosets used in cars and electronics—to be fully reused. Unlike common plastics, thermosets are usually impossible to melt down…
