Ceramic coating is not only eco-friendly and harmless but also thermally and chemically durable. However, foods easily adhere to the cookware on cooking due to hydrophilic coating layer from numerous hydroxyl groups on silica surface. To solve such problem, we prepared ceramic coating solution with enhanced non-stick property. This hydrophobic coating was materialized by rough surface from nanofibers added into ceramic solution. Cellulose nanofibers (CNFs) contained in silica colloidal solution for ceramic coating made the surface of coating irregularly and rough. The average roughness of ceramic coating surface increased when CNFs were added according to the results from 3D microscope. Also, ceramic coating incorporated CNFs was more thermally stable so its thermal degradation temperature also increased compared to that of base ceramic solution. We anticipate that the non-stick and thermally stable pottery can be fabricated by applying this CNF-incorporated ceramic coating. |
