The bulk rheological properties, such as shear viscosity and storage & loss moduli of perfluoropolyether (PFPE) with different molecular weights and endgroup functionalities were examined via a rotational rheometer. Equilibrium and non-equilibrium molecular dynamics simulations were performed to provide a molecular visualization tool to clearly understand the intrinsic nanostructure as well as to predict the bulk shear viscosity, which reveals a strong dependence on temperature and PFPE molecular architecture.
