Improving the wet strength of filter paper while maintaining the current porosity
10 November, 2016
“I propose reinforcing the paper with an inorganic, organic or organic/inorganic hybrid layer through layer-by-layer, atomic layer deposition or pulsed chemical vapor deposition.”
We manufacture filter papers for single serve coffee capsules. Hot pressurised water is injected through the top of the capsule into the coffee powder, passes through the paper filter and then leaves the capsule through the bottom. In order to improve performance, these filters should be strong enough to withstand the pressurised water, while having the correct porosity to separate the coffee from the coffee powder.
The challenge is to find approaches to improve the wet strength of filtration papers while maintaining the current porosity.
One of my research interests is paper. I have quite a few publications and patents concerning paper-based technologies.
I thought about this problem and I think the best strategy would be to reinforce paper with an inorganic, organic or organic/inorganic hybrid layer through layer-by-layer, atomic layer deposition or pulsed chemical vapor deposition. If you are interested, we can get together and discuss.
