Regulating microstructures of interpenetrating polyurethane-epoxy networks towards high-performance water-lubricated bearing materials

Structural evolution and mechanical properties of polyurethane/epoxy interpenetration networks (PU/EP IPNs) as a function of PU content were comprehensively studied. In particular, tribological behaviors of the IPNs were investigated in water medium while varying lubrication regimes. Our results demonstrate that microstructures of PU/EP IPNs are closely dependent on stoichiometric proportions of their components. It is impressive that unlike...
