1. A composition comprising:
a plurality of repeating units, wherein each of the plurality of repeating units comprises:
a first layer of first particles having a first mean diameter, and
a second layer of second particles having a second mean diameter; and an intermediary material selected from the list consisting of ionomers, polymers, polymerizable monomers, resins, cyclodextrins or combinations thereof,
wherein said intermediary material allows mobility of and contact between the first particles within the first layer and mobility of and contact between the second particles within the second layer, whereby said contact allows momentum transfer between said particles, and
wherein the first mean diameter and the second mean diameter are different and are less than 500 nm; and
wherein the first particles or the second particles are core-shell particles having a core that is partly or completely filled with a liquid, a gas and/or a gel; and
wherein the composition attenuates a compression wave.
