“Nano-mechanical characterisation of functionalised cellulose fibres and fibre-fibre bonds”
As part of the project single cellulose fibres, fibre-fibre bonds and paper fleeces are functionalised with polymers. For a better understanding of the connection between fibre properties on micro- or nanometre scale and the functional properties of paper, the atomic force microscope and nano mechanical bending tests are used for investigation. Therefore, the spatial distribution of the polymer on paper fleece/fibres, the nano mechanic of polymer coated cellulose fibres in dependency of temperature and humidity and the strength of the inter fibre bonds of functionalised fibres are for interest. The gained knowledge is compared with fluorescence microscopy, confocal laser scanning microscopy and scanning electron microscopy to obtain a nano mechanical as well as a chemical image of the surface.
