Researchers from Bhabha Atomic Research Center Report New Studies and Findings in the Area of Flame Retardants (Layered silicate-polymer nanocomposite coatings via radiation curing process for flame retardant applications)

By a News Reporter-Staff News Editor at Life Science Weekly -- A new study on Flame Retardants is now available. According to news reporting from Maharashtra, India, by NewsRx journalists, research stated, "Polymer-clay nanocomposite (PCN) films were fabricated by uniformly dispersing organically modified montmorillonite clay (Cloisite 20A and 30B) in varying concentrations of 2%, 5%, 10% and 15% (w/w) in an optimized composition of aliphatic urethane acrylate (AUA)-Trimethylolpropane triacrylate (TMPTA) mixture by ultra-sonication followed by Co-60-gamma radiation induced curing."

The news correspondents obtained a quote from the research from Bhabha Atomic Research Center, "Radiation doses were optimized to obtain non-tacky, homogeneous thin films, which were subsequently characterized by UV-vis spectrophotometry, X-ray diffraction (XRD), small angle X-ray scattering (SAXS), Fourier transform infrared spectrometry (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) techniques. Gloss of the PCN films decreased, and fracture toughness and hardness of PCN films improved with the incorporation of the clay in the PCN coatings."

According to the news reporters, the research concluded: "Limiting Oxygen Indices (LOIs) of the samples were calculated from the thermogravimetric analyses data to ascertain the efficacy of the PCN films as potential flame retardant materials."
