Abstract:
"The goal of this project is to implement the industrial use of layer-by-layer
polyelectrolyte nanocoated pulp fibers, thereby to bring new technology to paper
making. The proposed work is based on our pioneering in the layer-by-layer
nanoassembly techniques and on our results on modification of lignocellulose fibers,
which made stronger paper and improved paper recycling. Layer-by-layer (LbL)
assembly is a nanofabrication technique which has been used to produce multilayered
films with nanometer precision through alternate adsorption of oppositely charged
components. The main work directions are as follows: 1) Fiber polyelectrolyte
nanocoating with control of thickness (in the range 5-50 nm), surface roughness, and
surface charge (negative and positive). 2) Development of new paper making processes
based on the mixture of LbL-nanocoated positive and negative fibers: Modifying
recycled fibers for electrostatic bonding. Drastic increase the percentage of LbL treated
recycled fibers in paper without loosing paper strength. 3) Scaling up our nanocoating
process to tens of kilograms and more. 4) Customizing the technology for patent
licensing, working with individual paper mills. The proposed LbL nanocoating will
increase paper recycling. We propose to develop specific polyelectrolytes for
commercial use in current pulp preparations to improve fiber surface properties for better
bonding and stronger paper."
