Recent research progress on graphene-based sound-absorbing materials

With the rapid development of transportation and industry, noise pollution has become another source of pollution after air and water pollution, so the development of high-performance sound-absorbing materials. is getting more and more attention. Graphene, as a new type of nano-material, is characterized by lightweight, excellent thermal stability and sound absorption, and can be combined with various components to improve the sound absorption performance of the material. The article first briefly introduces the current research status of graphene monolithic sound-absorbing materials, then discusses the application and research progress of graphene-based binary and ternary sound-absorbing materials in sound wave absorption, and finally looks forward to the future development prospects of graphene-based composite sound-absorbing materials.
