The effect of SiO2 on hydrophobic and mechanical properties of electrospun PVA nanocomposite fibers

The present study investigates the effect of SiO2 nanoparticle on the hydrophobic and mechanical properties of Poly vinyl alcohol (PVA)/ SiO2 nanocomposite fibers. Firstly, nanocomposite fibers based on PVA/ SiO2 were prepared via electrospinning method. Hydrophobic properties of nanocomposite fibers were determined via contact angle measurement instrument. Improvement in hydrophilicity of the polymer-air interface by addition of SiO2 was clearly evident in the observed contact angles of water on PVA/ SiO2 nanocomposite fiber mats. The tensile results show that the Young’s modulus of these nanocomposite fibers were greatly improved in presence of SiO2. At the same time, there was a deterioration in elongation at break and tensile strength of the nanocomposite fibers.
