Nano-celluloses - cellulose fibrils with diameters in the nanometer range - are materials from renewable resources with unique and potentially highly useful features. The nanodimensions of the structural elements result in a large surface area and hence powerful interaction of these materials with surrounding species, e.g. water, organic compounds, polymers, nanoparticles, or living cells. In addition, through appropriate modification of nano-cellulose or pre-treatments, various functional nanomaterials with outstanding properties or significantly improved physical, chemical, biological, as well as electronic properties can be developed. Thus, these materials open up the strongly expanding fields of nanocomposites and sustainable materials, as well as medical and life-science devices, to the natural polymer cellulose.

This talk intends to give an overview over different types of nano-celluloses and methodologies of how these materials are produced.

Furthermore, recent developments and novel applications making use of nano-celluloses will be outlined. Eventually, two advanced applications, developed in the Polymer and Composite Engineering group at Imperial College London, are presented: on the one hand the application of nano-cellulose in renewable polymer-composites and on the other hand the production of nanopapers applicable for the treatment of wastewater by nanofiltration.
