A Novel Process for the Manufacture of Auxetic Foams and for Their re‐Conversion to Conventional Form

Images showing the microstructure of conventional and auxetic foams produced through the traditional thermo–mechanical process and the novel chemo–mechanical process. Auxetic foams exhibit the unusual property of becoming fatter which when stretched a property which makes them superior to conventional foams in various applications ranging from smart tunable filters to vibration-proofing materials.
