摘要
聚氨酯是一种重要的阻尼材料,为了提高其阻尼性能,众多研究者对各种聚氨酯/填料体系都进行了研究,近年来纳米材料在阻尼材料方面的应用引起了更广泛的兴趣。介绍了在水声吸收、阻尼材料中的一些最新研究成果,特别是作为水声吸声材料的聚氨酯/纳米氧化锌复合材料体系。
Polyurethane is an important damping material. To increase its damping property, many polyurethane/filler composites have been studied, In recent years, there is more interesting in the use of nanomaterials for damping. The advance in damping and underwater acoustic absorption polymer materials is introduced, especially for polyurethane/nano-ZnO composites.
