- Abstract:
- ... Waste paper is an environmentally friendly source of cellulosic material. Here we propose a new treatment based on nanocrystalline cellulose (CNC) for paper preservation and consolidation. Suspensions of CNC were prepared by sulfuric acid hydrolysis using waste paper as cellulose source (CNCWP) and compared with CNC from cotton linter (CNCCL). Both CNCs were obtained with good yield, showing high ...
