Quality of Nanofibrous Mats in Relation to Rheological Characterization of PVB and PVB/Silica Solutions

摘要

Rheological properties are influenced by many factors ranging from the characteristics of the carrier fluid (poly(vinyl butyral)), solvent (methanol) and a filler (fumed silica nanoparticles) to the flowing conditions. There is compared rheological characterization of the neat PVB solution with the PVB/silica suspension. This characterization is confronted with quality of the corresponding nanofibrous mats and a role of elasticity is discussed. It is shown that in this case a role of elasticity is rather limited.
