sing a filament stretching rheometer (FSR) surrounded by a thermostatic chamber and equipped with a micrometric laser it is possible to measure large amplitude oscillatory elongation (LAOE) on elastomeric based networks with no base flow as in the LAOE method for polymer melts. Poly(dimethylsiloxane) (PDMS) based networks, considered as a model system for studying the development of soft elasticity, are mechanically characterized through reversed LAOE deformation, applying oscillatory measurements with several amplitudes and frequencies.
