Fabrication of large-sized robust carbon aerogel composites via pre-shrinkage-induced interfacial engineering
We report a strategy for synthesizing crack-free carbon aerogel (CA) composites by rationally matching the carbonization shrinkage of viscose fiber felts (VFs) with that of a phenolic resin (PR) aerogel matrix. The VFs were pretreated at elevated temperatures to induce controlled pre-shrinkage, followed by an in si...
