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 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

Polymer networks, which include everyday materials such as tires and contact lenses, play an essential role in modern life due to their ability to deform and recover. However, these materials are prone to fatigue and cracking over time, ultimately leading to failure and the release of microplastic and microrubber particles into the environment. This collaborative research project aims to advance the fundamental…
