The study of polyaniline sound absorbing film materials

摘要

In this paper, a new type of sound-absorbing film material was made, using polyaniline (PAN) doped graphite (G) as the basis, polymer as the film forming agent. Factors which affected the sound absorption properties were discussed, the results showed that sound absorbing properties were the best, when Surface resistance was 103Ω, film thickness was 300µm. On this condition, average absorption coefficient was 0.6, and the maximum value was 0.97.
