Effect of Nanosilicon Dioxide on Structure and Properties of Poly(Vinyl Alcohol)/ Sodium Carboxymethylcellulose Blending Film

Abstract:

Poly (vinyl alcohol) (PVA)/sodium carboxymethylcellulose (Na-CMC)/nanosilicon dioxide (nanoSiO₂) films were prepared by solution casting method. The structure, properties and morphology of the films affected by nanoSiO₂were characterized by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and mechanical testing. With the increase of nanoSiO₂ content from 0 to 2.3 wt%, tensile strength increased from 20.98 to 34.80 MPa, while further increase of nanoSiO₂ decreased the tensile strength. FTIR spectroscopy of the films confirmed that Si-O-C bonds and hydrogen bonding were formed among PVA, Na-CMC and nanoSiO₂, which was suggested to improve the tensile strength of the films.
