Sammanfattning
This study aimed to understand the effect of various rheological additives on the extensional viscosity of barrier coating dispersions. The apparent extensional viscosity was measured using a capillary viscometer. Additives tested include polyvinyl alcohol, polyethylene oxide, and carboxymethylcellulose. Some of the additives could substantially increase the extensional viscosity of the dispersions without increasing the shear viscosity outside the typical range of processability for a curtain coater.
