| 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. |
