Structural, optical, morphological and mechanical studies of polyethylene oxide/sodium alginate blend containing multi-walled carbon nanotubes

Multi-walled carbon nanotubes were added to mixture of polyethylene oxide (PEO)/sodium alginate (SA) (70/30 wt.%) films via the casting way. X-ray diffraction exhibited the amorphous behavior of the polymer samples, also showed a decrease in the crystalline ratio after the addition of Multi-walled c...

The optical properties of samples were investigated by ultraviolet and visible (UV/vis) spectroscopy and showed decrease in optical energy gap as the concentration of MWCNTs increased. Scanning electron microscopy (SEM) exhibited a homogeneous growth mechanism which denotes the partial compatibility between the nanocomposite components. The mechanical behavior measurements of the prepared samples showed improvement of the modulus of elasticity and tensile strength after adding MWCNTs.
