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 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2029.

Abstract

Plastics reinforced with tiny particles, known as polymer nanocomposites, are used throughout modern life, from aircraft and automobile components to microelectronics, batteries, and biomedical devices and drug delivery. The performance of these materials depends significantly on a thin region of polymer surrounding each particle, called the interphase, where the material behaves differently than it does away from…
