Molecular dynamics of poly(ethylene terephthalate)/poly(phenylene sulfide) nanocomposites with barium titanate

Abstract

Abstract:The relaxation processes and the properties of polymer/ceramic nanocomposites have been studied by the 1 H nuclear magnetic resonance methods. Nanocomposites of poly(ethylene terephthalate) PET and poly(phenylene sulfide) PPS with 0.25, 2.5 and 5% wt. barium titanate BT were prepared using a twin screw extruder and injection moulding machine. The spin-lattice relaxation time T 1 , second moment M 2 and the motional parameters as e.g. the activation energies in the nanocomposites were investigated. PACS
