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.

Hierarchically porous polymer coatings for highly efficient passive daytime radiative cooling | Science
New cheapish polymer coating to make a narrowband IR emitter that pumps through the LWIR atmospheric transmission window. So something can be cooled by exposing it to the sky.
