Abstract

Through the functionalization strategy of multi-walled carbon nanotubes (MWCNTs) with polyvinyl acetate (PVAc), dampening material for acoustic devices was sought. In this paper, we investigated the effect of polymer grafting of MWCNTs on the frequency response based on a mechanistic basis. We have found that vibration reduction ability of the MWCNTs incoporated polymer has a maximum increase of 70% compared with pure polymer. Composites with pristine MWCNTs and polymer grafted MWCNTs were found to exhibit similar dynamic mechanical behavior in the frequency above 1000 Hz.
