Improved Temperature Stability of Atomic Layer Deposition Coated Cellulose Nanocrystal Aerogels

  • Sean W. Smith (a1), Han Chan (a2), Christian Buesch (a3), John Simonsen (a2) and John F. Conley (a1)...


Atomic layer deposition (ALD) was used to coat cellulose nanocrystal (CNC) aerogel scaffolds with a thin conformal layer of Al2O3. Electron probe microanalysis indicates that the penetration of Al2O3 into the aerogel was greater than 50 μm. Thermogravimetric analysis (TGA) shows that Al2O3 coated CNC aerogel composites have improved temperature and oxidation resistance.
