Catalytically Active

Cellulose–TiO2 membranes with photocatalytic activity were prepared by non-solvent induced phase separation from cellulose solutions in ionic liquids or from cellulose acetate solutions in organic solvents followed by deacetylation.

In this work we investigated the possibility to use electrophoretic deposition from organic solvents in order to deposit catalytically active surface-stabilized nanoparticles on a substrate. This permits to functionalize a surface by depositing a catalytic layer or simply offers a way to collect the synthesized nanoparticles e.g. for subsequent characterization. As an example, Co nanoparticles were prepared using a sonochemical method, and subsequently deposited on a substrate by electrophoretic deposition. We used ionic liquids (IL) in order to increase the ζ-potential of the nano particles.

Chitosan Membranes

Biofouling, due to the existence of bacteria in water, becomes one of the barriers in cellulose acetate (CA) membrane applications. Although chitosan has been incorporated into CA membranes, its antimicrobial activity has not been improved significantly yet. In this study, cellulose acetate-chitosan membranes were prepared by modification using ZnO and Al2O3 nanoparticles during phase separation method. The membranes were then characterized in term of water permeability, and surface morphology. The anti-bacteria property was examined by using gram-negative bacteria. Modification of cellulose acetate-chitosan membranes with ZnO and Al2O3 nanoparticles have not shown optimal results where no clear zones around the membrane are visible.
