So the final report is due by 29 December 2029.

Abstract

Creep, the deformation of a material under a constant load over time, is a problem that affects all classes of materials including polymers. It has been estimated by the Society of Plastics Engineers that creep is the cause of nearly a quarter of plastic component failures. Palygorskite nanoclay was the basis for the renowned Maya Blue pigment, which was used to color murals in Mesoamerican temples. These murals…
