Pilot Scale Production of Interactive Zinc Oxide Paper and its Multiple Applicability, 19PaperCon
Large scale production of paper offers both the blessing and curse associated with the economy of scale, i.e. while offering a low production cost it also requires the production of large volumes. To be able to offer a single material to multiple markets we actively searched a paper filler material with several interactive properties that can be exploited in different ways depending on the context during use.
Zinc oxide filler particles meet these interactive requirements since they can respond to electrical voltage, photonic illumination and mechanical bending. In this work we report on successful pilot scale papermaking trials to produce papers filled with zinc oxide tetrapodal microwhiskers. The FEX pilot paper machine (web width 30 cm) was run at a low speed (100 m/min) and showed good retention at 15%, 30%, and 45% zinc oxide filler levels. The produced material was white as normal printing paper to the naked eye offering no clues about its versatile interactive properties. The zinc oxide paper was further explored in selected applications spanning UV sensors and photocatalytic filters to purify air and water.
