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.

The present disclosure relates to a multilayer composite that may include a first barrier layer and a first foam layer. The first foam layer may include a polyurethane-based matrix component, and a flame retardant filler component. The multilayer component may also have a HBF flammability rating as measured according to ASTM D4986.

The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse in direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 μm. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

Provided is a functional laminate including a porous intermediate layer having air permeability laminated between a porous surface layer and a resin foamed layer, the porous intermediate layer having an affinity to a foaming resin forming the resin foamed layer.
