[nanoPost] Nanomaterials for the Pulp & Paper Industry

Company USA

Forestry, as the raw material supplier for the paper and pulp industry, faces global demands to supply the Pulp & Paper Industry which has to produce new and improved paper products.  

The company are using Layer by Layer (LbL) Assemblies which are readily implemented into current paper making processes.

Current R&D is in:

1) Nanoassembly on pulp fibers, to systematically modify their surface charge and roughness (to decrease pulp beating for energy saving); an application of nanocoating to make pulp homogeneous; development of a repair process for broken fibers for better recycling.  Biometric approach for synthesis in fiber lumen to provide new properties (strength, conductivity). Using cellulose microtubules as a template for nano-, micro-integrated devices.

2) On pre-formed paper, to develop controlled loading (1 to 5 wt %) with nanoparticles, including clay and ceramic nano-tubules, and to enhance wet and dry strength. Control of paper wettability for better printing. Modification of permeability for paper filters by nano-organized polymer coating.

3) Smart paper with embedded sensors and polymeric micro devices - fluorescent nano-layers and polymeric microchips to convert paper passive matrix to active matrix.

4) Nano- and microcapsules for drug sustained release and targeted delivery, and stabilizing colloidal suspensions.
