| Abstract | A series of polyurethane (PU) samples based on poly(tetramethylene glycol)/epoxy resin (EP) graft interpen- etrating polymer networks (IPNs) were prepared and their damping, thermal, and mechanical properties were system- atically studied in terms of composition and the value of the PU isocyanate index (R). The damping properties and thermal stability measurements revealed that the formation of PU/EP IPN could improve not only the damping capac- ity but also the thermal stability. Meanwhile, mechanical tests showed that the tensile strengths of the IPNs decreased while their impact strengths increased with increasing PU content. The value of R also had significant impacts on the properties of the IPNs when the PU and EP ratio was fixed, which could be an effective means for manipulating the fab- rication of PU/EP IPNs. The morphologies of the PU/EP IPNs were observed by SEM and AFM characterization and the relationship between the morphologies and properties is discussed. With the results in hand, the PU/EP IPNs hold promise for use in structural damping materials. |
