摘要：

The present investigation deals with the preparation and characterization of nanocomposites of poly(ether ether ketone) (PEEK) containing nanosized nickel filler up to 3wt% loading. Characterization of the developed nanocomposites has been carried out by various advanced analytical techniques. Thermogravimetric analysis study depicts that the prepared nanocomposites exhibit enhanced thermal stability. Dynamic mechanical analysis (DMA) technique has been utilized to investigate the viscoelastic deformation of nanocomposites. From DMA studies, it has been demonstrated that with the increase in nano-nickel content, the stiffness of nanocomposites decreases and a very minute change in glass transition temperature (T-g) has been noticed. The resulting nanocomposites show the optimum improvement in Young's modulus, tensile strength, flexural strength and flexural modulus. Scanning electron microscopy study reveals that he dispersion of nano-nickel particulates is uniform throughout the PEEK matrix.
