Abstract: The present disclosure provides a cellular foam composition, a method for producing and using the same. One particular aspect of the disclosure provides a cellular foam composition comprising a plurality of foam layers, where each foam layer is made from a hollow microstructure material. In particular, the density of the hollow microstructure material in each foam layer is different from the density of the hollow microstructure material that forms the adjacent foam layer. In some embodiments, cellular foam compositions of the disclosure further include an interfacial layer comprising interfacial voids in between adjacent layers.
