| 聚对苯乙炔（PPV）材料具有电导、顺磁、能量迁移和转换等特性，其应用研究很热很广，但其在吸声领域尚未见报道过。将PPV与石墨烯、铜酞菁等材料按一定比例共混成膜，制得了新型导电复合薄膜吸声材料。结果表明，该薄膜吸声材料具有宽吸声频带和强吸声能力，在声波125Hz～4000Hz频率范围内的平均吸声系数大于0.5，最大吸声系数达到0.99，尤其是在中低频范围（125Hz～1000Hz）内吸声性能远比一般吸声材料优异。 |

| Poly-phenylene vinylene (PPV) materials have conductivity, paramagnetic, energy, migration and conversion characteristics, its application the research very hot very wide, but its sound absorption field has not been reported before. PPV and graphene, copper phthalocyanine, etc. blend deposition of material by a certain percentage, the prepared novel conductive composite film sound absorbing material. The results showed that the film sound absorbing material having a wide the sound absorption bands and strong absorption capacity, the average absorption coefficient in the acoustic frequency range of 125Hz ~ 4000Hz is greater than 0.5, a maximum absorption coefficient of 0.99, especially in the low-frequency range (125Hz ~ 1000Hz) within the sound absorption performance than the general sound-absorbing material is excellent |
