Notes:
The nanocomposite coatings were prepared on the surface of PVC substrate using spinningtechnique with attempts of introducing nanosized iron oxide particles with different morphology into theorganic-inorganic hybrid matrices. The hybrid matrices were derived from 3-glycidoxypropyltrimethoxysilane(GLYMO) and tetraethoxysilane (TEOS) with a process of hydrolyzing and condensation.Nanosized iron oxide particles were synthesized by hydrolysis of FeCl3 solution at different pH value anddifferent temperature. The effects of different additions on nanomechanical properties of thenanocomposite coatings were investigated using X-ray powder diffraction (XRD), transmission electronmicroscopy (TEM) and MTS Nano Indenter XP system. It was found that the acicular α-FeOOH andspherical α-Fe2O3 particles were synthesized, both of them dispersed homogeneously. Nanoindentationand nanoscratch behaviors of the nanoindenter system showed that both of the nanocomposite coatingsreinforced the nanomechanical properties of the PVC obviously. Especially, the contribution of acicularα-FeOOH was more remarkable than the spherical α-Fe2O3
