Nanocellulose is a promising new renewable and low-cost nanomaterial which has potential applications in many different fields from biomedical to electronic applications. Here, we report the fabricated aerogels from aqueous CNF and CNC dispersions using freeze-drying technique and analysis of their structural analysis using different microscopic techniques. Also, we report the development of dispenser for aqueous nanocellulose solutions to be installed into 3D-printer system.
