Abstract:
In this work, Polyacrylamide/ Polyethylene glycol solutions of
different molecular weights for Polyethylene glycol and different
concentrations (17, 29, 38, 45 and 57 %) of ZnO nanoparticles were
prepared by dissolving 0.5g of Polyethylene glycol in 20mL
Polyacrylamide, then adding different concentrations of ZnO
nanoparticles. Relative viscosity values are calculated by used the
efflux time of the solutions, the viscosities(relative viscosity (ƞr),
specific viscosity (ƞsp), reduced viscosity (ƞred) and inherent viscosity
(ƞint) were calculated for all solutions, where measurements indicated
an increase in these properties with increased concentration of ZnO
nanoparticles and increased molecular weight of Polyethylene glycol.
Viscosity is significant parameters during electrospinning process, and
if the molecular weight increases, the viscosity of the solutions
increase, making subsequent synthesis and purification more difficult.
the constants KH and KK were calculated from the slopes of the
viscosity values related to the Huggins and Kramer equations. These
results can be used in many applications and scientific studies.
