|Title:||Properties of PS/TiO2 electrospunfibres using limonene as a solvent|
|Abstract:||Limonene, a natural solvent, has been used for producing polystyrene (PS) nanocomposite (NC) fibres. Nanocompositefibres of PS are prepared by electrospinning of a homogeneous solution of titanium dioxide (TiO2) nanoparticles (NPs) and PS. X-ray diffraction (XRD) pattern of PS nanocompositefibres confirms the presence of TiO2 nanoparticles in the samples. FTIR spectra of PS nanocompositefibres obviously show that there is no chemical linkage or interaction between PS and TiO2 nanoparticles in the resulting composites fibres. The morphology of PS electrospunfibres and PS/TiO2 nanocompositefibres is investigated by SEM and FE-SEM. FE-SEM images of electrospunfibres reveal some aggregation of TiO2 nanoparticles. The results also show that increasing TiO2 nanoparticles reduces PS electrospunfibres diameter. Also, the UV protection of PS electrospunfibres is enhanced due to the increase in TiO2 nanoparticles load. Tensile strength and elasticity modulus first show an increase up to 4 wt% of TiO2 and then a decrease at higher loading. Differential scanning calorimeter (DSC) thermograms for PS electrospunfibres indicate that the introduction of TiO2 nanoparticles decreases the glass transition temperature (Tg).|
