Abstract
Described is a membrane comprising a microlayer polymeric composite having at least about 10 microlayers. The microlayers are each individually up to about 100 microns thick and alternate between at least one fluid barrier material and at least one elastomeric material. The membrane can be formed into a pressurized bladder or cushioning device for many applications, including footwear and hydropneumatic accumulators.
