Sound absorption of electrospun polyvinylidene fluoride/graphene membranes

In this study, a novel sound-absorbing material was developed using electrospun piezoelectric polyvinylidene fluoride (PVDF) membranes. The effects of graphene (Gp) and electrospinning on the crystal structure and piezoelectric properties of PVDF/Gp nanofibrous membranes were examined. The results showed that electrospinning effectively induced the beta phase and increased the piezoelectricity. Adding graphene further improved the piezoelectric...
