Abstract

Introduction: The effects of different solid substrates including: CARBON NANOFIBERS (CNFs), activated carbon, alumina, silica, and poly vinyl pyrolidone (PVP) were compared for high pressure synthesis of POLYTETRAFLUOROETHYLENE (PTFE, (CF2)n) nanoparticles via the ADSORPTION of thermally synthesized TETRAFLUOROETHYLENE (TFE, C2F4) as monomer.Aim: Syntheses and characterization PTFE nanoparticles and also in this paper, a new method is proposed for the synthesis of PTFE nanoparticles via ADSORPTION of TFE monomer on different solid substrates.Materials and Methods: Electron microscopy, FT-IR spectroscopy, and thermogravimetric analysis (TGA) were used for characterization of PTFE nanoparticles on different solid substrates.Results: under similar conditions, the average diameter of the PTFE nanoparticles was around 90 nm for CNFs, 130 nm for PVP, 150 nm for alumina and around 200 nm for silica.Conclusion: Different solid materials have various capacities for the formation of PTFE nanoparticles, depending on their size, shape, and their morphology. In fact, the amounts and the sizes of synthesized PTFE nanoparticles are strongly dependent on the nature of the solid surface substrate.
