Direct Ink Write (DIW) 3D Printed Cellulose Nanocrystal Aerogel Structures

Abstract Pure cellulose nanocrystal (CNC) aerogels with controlled 3D structures and inner pore architecture are printed using the direct ink write (DIW) technique. While traditional cellulosic aerogel processing approaches lack the ability to easily fabricate complete aerogel structures, DIW 3D pri...
