摘要
Polyurethane is a widely used viscoelastic polymer known for its exceptional damping properties. This paper focuses on the introduction of disulfide and imine bonds into the polyurethanematrix to enhance its damping capabilities, mechanical properties, and self-healing ability. Dynamic mechanical analysis shows that the synergistic effect of disulfide bond and imine bonds extends the effective damping temperature range of the polyurethane to 118 degrees C (-18 to 100 degrees C), while the effective damping frequency extrapolates to a range of 10(-2)-10(5) Hz. Furthermore, the addition of imide bonds compensates for the relatively low mechanical properties associated with disulfide bonds, allowing the polyurethane to achieve a tensile strength of 14.7 MPa at room temperature. Self-repair tests reveal that the combined action of these two dynamic bonds enables a remarkable 97% repair efficiency of polyurethane, exhibiting excellent self-healing performance. This study presents a novel approach to enhance the comprehensive properties of polyurethane.
