A new approach to the synthesis of highly stable aqueous colloids of coordination polymer nanoparticles was developed by using water-soluble chitosan beads as template and as stabilizing agent. The method consists in the synthesis of nanocomposite beads containing cyano-bridged coordination polymer nanoparticles via step-by-step coordination of the metal ions and the hexacyanometallate precurso...

The effect of carbon nanofibers (CNFs) on the electrical properties of Poly(vinylidene fluoride-hexafluoropropylene) (P(VdF-HFP)) based gel polymer electrolytes has been investigated in the present work. The length and diameter ranges of CNFs used in the present work are 5-50 μm and 200-600 nm respectively. The nanocomposite gel polymer electrolytes have been synthesized by solution casting tec...

Abstract-In-situ chemical polymerization was used to synthesize PPy/ TiO2 nanocomposite. The nanocomposite was characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Scanning electron microscopy (SEM) and Energy dispersive X-ray spectroscopy (EDX) to ensure the crystallite size, functional groups and morphology of the polymer nanocomposite. The band gap of th...

Scaffolds play a pivotal role in the tissue engineering paradigm by providing temporary structural support, guiding cells to grow, assisting the transport of essential nutrients and waste products, and facilitating the formation of functional tissues and organs. Single-walled carbon nanotubes (SWNTs), especially ultra-short SWNTs (US-tubes), have proven useful for reinforcing synthetic polymeri...

cofe2o4 magnetic nano particles (mnps) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. then, a hybrid nanocomposite of polyaniline (pani)-cofe2o4 mnps has been electrodeposited directly on a stainless steel wire by the potentiostatic method. microscopic images of electrodeposited pani and pani-cofe2o4 nanocomposite coatings were obtained by s...

various morphologies of silica nanoparticles were synthesized by a microwave-assisted pechini method. silica nanostructures were synthesized via a fast reaction between tetra ethyl ortho silicate and ammonia at presence citric acid and other effective agents in pechini procedure. then for preparation of polymer-matrix nanocomposites, sio2 nanoparticles were added to poly carbonate (pc) and poly...
