文摘
New and well-dispersed polymer nanocomposites have been developed. Polypyrrole nanoparticles with an average nanoparticle size of 161 nm have been prepared. The polypyrrole nanoparticles were dispersed uniformly in acrylonitrile–butadiene–styrene polymer producing new polymer nanocomposites. The dispersed nanoparticles present a good flame retardant behavior for the developed polymer nanocomposites. Polypyrrole nanoparticles were doped with phosphoric acid, and the effect of dopant on thermal stability and flame retardancy was studied. Mass loadings effect of different polypyrrole nanoparticles on the dispersion, flammability and thermal properties of new polymer nanocomposites were investigated. Flame retardancy and thermal stability were improved. Rate of burning of new polymer nanocomposites achieved 82 % reduction compared to blank polymer. Peak heat release rate and total heat release of the polymer nanocomposites were reduced achieving 78 and 31 % reduction, respectively. Interestingly, the emission of toxic gases was suppressed by 35 % for both CO and CO2.
