Abstract (Summary)
Generation Of A Novel TiO2 - Composite – A Feasibility Study by Mathias E.V. Lindström The objective of this work was to explore the feasibility of generating a fiber-latex- TiO2-composite material that could be used as an additive in the papermachine wet end. By initially binding a cationic latex and subsequently anionic TiO2 to the fiber surface and then curing the latex, it was envisioned that the pigment would be strongly retained in a latex film on the fiber surface. This novel additive could be utilized in papermaking operations achieving high TiO2 retention and substantial cost-savings. Dispersion turbidity and microscopy were used to monitor experiments. Data were generated on the interaction between fiber and cationic latex, and a fiber-latex intermediate and TiO 2. Retention levels of TiO2 in the range of the target value were achieved, and stability tests proved the material resistant to normal pH and shear stresses. However, the cured composite proved difficult to redisperse and a different approach for curing must be explored.
