摘　　要：聚对苯乙炔(PPV)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较强吸声能力,在声波125~4000Hz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,同时是在中低频范围(125~1000Hz)内吸声性能远比一般吸声材料优异。Poly（wphenylene vinylene） （PPV） has such properties as conductivity, paramagnetizm, energy migration and conversion,it becomes widely and fascinatety in research of its application. But it has not been reported in sound ab- sorption before. In oder to get a new conductive composite film sound-absorbing material, PPV,graphene and copper phthal- ocyanine were blended to form film by a certain percentage. The results showed that the sound-absorbing of the material had a wide sound absorption bands and strong absorption capability,in the sound waves 125Hz^4000Hz frequency range, t average absorption coefficient was at 50 %, maximum absortion coefficients reached 99 %. Especially,it had more excellent sound absorption performance than the general sound-absorbing material in the low and medium sound waves frequency range（ 125 Hz- 1000 Hz）.
