A novel compressed carbon dioxide assisted fabrication method is demonstrated to produce auxetic PU foam. Auxetic PU foams can be fabricated at room temperature (25 °C) in several seconds with compressed CO 2 . This technology overcomes some key challenging issues in the large‐scale production of auxetic PU foams.
