Cellulose nanofibres and nanofibre materials
From wood and agriculture residues, we are developing a series of nanocellulose materials: micro fibrillated cellulose (MFC), nano fibrillated cellulose (NFC) and nanocellulose crystals (NCC). These three types of nanocellulose can be combined with nanoparticles to develop recyclable composites that are very strong and flexible or provide gas and water vapour barriers. Applications are in food preservation and lighter packaging, low cost/disposable reverse osmosis membranes for water and food processing purification and industrial air filters. We are also exploring new technology and concepts to improve the production of cellulose nanofibers.
Our current projects focused on:
- New barrier materials from cellulose nanofibers
- New methods to rapidly make sheets from cellulose nanofibers for filter applications
- New sources of cellulose for nanofiber production to reduce energy consumption
- Methods to quantify cellulose nanofiber quality development
The development of nanocellulose based antimicrobial materials using bis(phosphinato) bismuth complex has also been explored. Morphological studies of the sheets revealed the overall distribution of the complex throughout the nanocellulose matrix. The composite sheets were able to inhibit the growth of bacteria and fungi, including strains of multi-drug resistant bacteria.
