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 30 November 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 30 March 2029.

Abstract

This project focuses on special materials called "polymer brushes," which are tiny, hair-like chains attached to surfaces. These brushes can change how they behave based on their environment — such as changes in acidity or salt levels. Because they are low-cost, flexible, and easy to make, polymer brushes have the potential to be used in water purification and environmental sensing. However, scientists do not yet…
