高分子吸声材料

Advances in Sound Absorption Polymers

新型吸声材料要求宽频、强吸收且综合性能良好。高分子材料具有粘弹内阻尼的特性 ,品种繁多 ,易于进行分子设计、材料设计和成型加工 ,是满足该技术要求的首选材料。本文结合近年来高分子吸声材料的应用及研究 ,从吸声机理和结构设计的角度 ,讨论了高分子材料的声学特性与研究进展 ,并展望了高分子吸声材料的前景。

Due to several advantages over other existing materials, including excellent viscoelasticity and good processibility, polymers are broadly applied to preparation of new sound absorption functional materials. The essential characters, applications and mechanisms of sound absorbtion polymers are discussed in detail. The latest developments in this area are also reviewed.
