The main objective of this work is to elucidate the crystalline structure of poly(dimethylsiloxane) (PDMS). Silica-filled PDMS elastomers are first synthesized by either physical mixing or in-situ sol-gel loading to obtain specimens that can sustain the extensions necessary for our purpose. Coupling tensile tests and X-ray diffraction (WAXD) at room temperature, it was found that the sol-gel silica filled samples exhibited an anomalously high strain amplification factor. Thereafter WAXD patterns of PDMS elastomer under different extensions was collected at low temperature (typically -100 °C) and the comparison between experimental data and simulations unambiguously demonstrated that the impressive pattern changes observed with increasing de...
