摘要：

Using a filament stretching rheometer 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)-based networks, considered as a model system for studying the development of soft elasticity, are mechanically characterised through reversed LAOE deformation, applying oscillatory measurements with several amplitudes and frequencies.
