Fabrication of MgMoO4-PVA and MgMoO4 fibrous webs via a direct high voltage electrospinning process
Mixtures of (CH3COO)2Mg·4H2O and (NH4)6Mo7O24·4H2O containing 0.7, 1.0 and 1.3 g of poly(vinyl alcohol) (PVA, 125,000 MW) were electrospun by +15 kV direct voltage to form fibrous webs. In the present research, the fibrous web of the 1.3 g PVA was characterized by a thermogravimetric analyser (TGA),...
