dc.description.abstractEnA simple and easy way is proposed for the fabrication of a highly attenuating material for underwater acoustics. The approach consists in the introduction of porous polymer beads into a polyurethane matrix. The porous beads are prepared using an emulsion templating approach and two different processes are used. The first one uses microfluidics to synthesize beads of controlled diameter and porosity. The control over the bead size allows for the selection of the frequency range where the material exhibits the highest acoustic attenuation. The second one uses a double emulsion approach and allows for the production of much larger quantities of beads. Both approaches lead to materials exhibiting much higher acoustic absorption than the one obtained using most commonly used microballoons inclusions. We present both the synthesis procedures and the structural and acoustic characterizations of the beads and the final acoustic materials. a.
