By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Life Science Research. According to news reporting from Tehran, Iran, by NewsRx journalists, research stated, "The effect of the glassflake nanoparticles on the rheology, morphology and protective properties of epoxy/glassflake nanocomposites has been studied in this work. Mechanical mixing and sonication process were used to incorporate nano-glassflakes (NGF) into the epoxy."
The news correspondents obtained a quote from the research from Iran Polymer and Petrochemical Institute, "Effects of the time and method of mixing on the morphology and dispersion quality of NGF/epoxy were studied by means of scanning electron microscopic (SEM). Results showed that a 30 min mechanical mixing followed by a 30 min sonication is a best mixing process to design nano-scale glassflake composites. The rheological analysis of epoxy pre-polymer/NGF dispersions indicates that an addition of NGF up to 1 wt% forms microstructure and improves the rheological properties. Barrier properties of the epoxy/NGF coated samples were evaluated by electrochemical impedance spectroscopy (EIS) as a function of immersion time in a sodium chloride solution (5 wt%)."
According to the news reporters, the research concluded: "The experimental results showed that the barrier properties of the epoxy/NGF coating systems improved by an increase of the NGF content up to 0.5 wt%."
