Correction: Facile fabrication of core/shell structured SiO2/polypyrrole nanoparticles with surface modification and their electrorheology

摘要: We synthesized conductive polypyrrole (PPy) coated silica core–shell structured nanoparticles, and investigated their electrorheological (ER) characteristics under electric fields applied when dispersed in silicone oil. Silica nanoparticle surfaces were initially modified using 3-(trimethoxysilyl)propyl methacrylate as a modifying agent to enhance the chemical affinity for more stable particle formation with PPy shells. Scanning electron microscopy transmission images provided evidence of structure morphology fabricated particles. ER behavior obtained particles an insulating oil observed via controlled shear rate test rotational rheometer, while fibrillation fluid was optical microscopy. The resulting responses show that composed silica/PPy nanoparticles exhibits typical field. A CCJ model used explain flow curves overall range along dielectric spectral measurements.
