Void‐Free Layered Polymeric Architectures via Capillary‐Action of Nanoporous Films - Lee - - Advanced Materials Interfaces - Wiley Online Library
Using carbon fiber (graphene?) thin films in composites (both in between the layers and the overwrap) to strengthen the composite, as running a current through the thin film causes a capillary action to squeeze out air voids and heat the resin for curing.

Tardigrades Use Intrinsically Disordered Proteins to Survive Desiccation: Molecular Cell
They use a fancy gene driven protein made when stressed (so not premade and waiting like nematodes and shrimp), that vitrifies the the damn things. So the protection mechanism is that the Tardigrade turns to glass when dried.
