Splet01. jan. 2015 · Polydimethylsiloxane (PDMS) is the most known organosilicon rubbery polymer and its glass transition temperature is about −150 °C. PDMS, often referred to as “silicone rubber,” can be polymerized from different monomers by hydrolysis and anionic, cationic, emulsion, and radiation polymerization process (Mark 2009 ). Splet18. maj 2005 · We studied temperature and pressure dependence of PDMS decomposition by following the rate of production of methane in the ReaxFF MD simulations. We tracked the temperature dependency of the methane production to extract Arrhenius parameters for the failure modes of PDMS. Furthermore, we found that at increased pressures the rate …
