Although these force fields have shown effectiveness in predicting certain material properties, many remain insufficiently validated for other thermodynamic and transport characteristics. It is crucial to assess the precision and reliability of these force fields in predicting the properties of common materials within MD simulations. However, a comprehensive benchmarking study for PDMS systems has yet to be conducted. Moreover, a critical issue remains as to whether these models that are parameterized with certain experimental data relevant to thermodynamics can reliably predict other key properties in dynamics and rheology, such as viscosity and thermal conductivity. Nevertheless, the challenge of transferability continues to pose difficulties in the force field development community. Extensive and systematic benchmarks are genuinely required for conducting reliable and accurate molecular simulations of PDMS materials.
