Different Structures of PVA Nanofibrous Membrane for Sound Absorption Application

Popis výsledku v původním jazyce

The thin nanofibrous layer has different properties in the field of sound absorption in comparison with porous fibrous material which works on a principle of friction of air particles in contact with walls of pores. In case of the thin nanofibrous layer,which represents a sound absorber here, the energy of sonic waves is absorbed by the principle of membrane resonance. The structure of the membrane can play an important role in the process of converting the sonic energy to a different energy type. Thevibration system acts differently depending on the presence of smooth fibers in the structure, amount of partly merged fibers or structure of polymer foil as extreme. Polyvinyl alcohol (PVA) was used as a polymer because of its good water solubility. Itis possible to influence the structure of nanofibrous layer during the production process thanks to this property of polyvinyl alcohol.
