Opposite Effects of SiO(2) Nanoparticles on the Local α and Larger-Scale α’ Segmental Relaxation Dynamics of PMMA Nanocomposites
The segmental relaxation dynamics of poly(methyl methacrylate)/silica (PMMA/SiO(2)) nanocomposites with different compositions ([Formula: see text]) near and above the glass transition temperature were investigated by mechanical spectroscopy. At [Formula: see text] ≤ 0.5%, the α peak temperature har...
