University of Illinois scientists have fabricated the world’s smallest chain-mail fabric that consists of a network of small rings about 500 microns in diameter and even smaller links about 400 microns long. The rings and links are built upon a planar substrate and then released to create a flexible sheet that can bend along two axes and drape over curved surfaces.

Because the rings and links can slide and rotate against each other, the fabric possesses unique mechanical and electrical properties. These properties could prove useful for the development of smart fabric and wearable electronic devices for pervasive computing.

A coating that is hard and has a high modulus of elasticity is needed for application to polyvinyl alcohol (PVA) optical films. Excellent coating adhesion and optical transparency are mandatory. The coating must withstand a force greater than 13,000 MpA, and offer a pencil hardness of B or over.To respond to this Tech Need click here.

Wet coating technologies are needed that show excellent weathering and durability performance. The coatings need to be applied successfully to mainly glass substrates and need to be suitable for application in a solution. They also need to be able to be used as a binder or cross-linking component of coatings comprising fillers such as colloidal nano-particles. To respond to this Tech Need click here.
