| Abstract: |
| The research progress of polymer-based underwater acoustic materials at home and abroad
was summarized. The sound absorption mechanism of polymer-based sound absorbing materials was
introduced，and the formulation，structure design and application fields of fillers，foams and structural sound
absorbing polymers were highlighted. From the aspects of sound absorption mechanism，formulation design
and application，the research status of polymer-based sound-permeable materials，anti-sound materials and
decoupling materials were reviewed. Finally，the development trend of polymer-based underwater acoustic
materials with wideband，wide-temperature range and high hydraulic pressure resistance was explored. |
