Viscoelastic polymer materials exhibiting high damping capacity within a specified frequency–temperature range effectively dissipate mechanical energy as heat, thereby mitigating damage induced by vibrations and impact loads.
Description
However, developing a convenient method for precisely designing damping materials with tunable energy dissipation properties across a desired frequency–temperature range remains challenging. Herein, we present a strategy for fabricating high-damping polyborosiloxane (PBS) elastomers (PBSEs) with tunable damping performance across a specified frequency–temperature range.
This is achieved by precisely modulating the PBS relaxation behaviorspecifically, through systematic variation of both the B–O bond content and the molecular weight of the PDMS diol precursors. We found that the resultant PBSEs exhibit controllable high-damping performance across an ultrawide frequency range (tan <i>δ</i> > 0.3, 10<sup>–3</sup> to 10<sup>2</sup> Hz) and temperature range (tan <i>δ</i> = 0.5–0.6, −20 to 150 °C).

Moreover, PBSEs exhibit excellent impact-protective performance compared with commercial materials and attenuate impact force by more than 95%. This unique design concept will provide a convenient approach to developing advanced damping materials.
