Preparation of Cellulose Nanofibrils by High Pressure Homogenizer and Cellulose-Based Composite Films
Introduction Cellulose fibers obtained from renewable resources such as wood become of more and more interest as reinforcing agents in composites, because they are biodegradable and harmless for the ecological system. Additionally, they have promising mechanical properties and are cheaper than conventional synthetic fibers. Within cell wall layers of fibers, the cellulose with high tensile properties exists as a system of fibrils embedded in the three dimensionally distributed lignin in wood struct ure. Depending on the acid hydrolysis with sulfuric acid and hydrochloric acid, the dimensions of the partly crystalline fibrils of wood can be various. To use the potential of fibrils, the fragmentation of cellulose fibers into smaller units has been attempted by mechanical treatment with high pressure homogenizer.
