Simulations on the thermal decomposition of a poly(dimethylsiloxane) polymer using the ReaxFF reactive force field.
TL;DR: To investigate the failure of the poly(dimethylsiloxane) polymer (PDMS) at high temperatures and pressures and in the presence of various additives, the ReaxFF reactive force field is expanded to describe carbon-silicon systems and initial thermal decomposition products are CH(3) radical and the associated polymer radical, indicating that decomposition and subsequent cross-linking of the polymer is initiated by Si-C bond cleavage.
Journal ArticleDOI
ReaxFFMgH reactive force field for magnesium hydride systems
TL;DR: A reactive force field is developed for magnesium and magnesium hydride systems that reproduces the QM-derived cell parameters, density, and the equations of state for various pure Mg and MgH(2) crystal phases as well as and bond dissociation, angle bending, charge distribution, and reaction energy data for small magnesium hyDRide clusters.
