PDMS/MWCNT nanocomposite films for underwater sound absorption applications

Polydimethylsiloxane (PDMS) nanocomposite films for underwater sound absorption applications are presented. Films were fabricated by a spin coating method and characterized using XPS, FTIR, TGA, SEM, tensile testing, and elastic cold-neutron scattering. The XPS results reveal the addition of surfactant and carboxyl-functionalized multi-walled carbon nanotube (MWCNT-COOH) increased the components of C and O atoms by 4.12% and 2.81%, respectively,...
