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 CO2. This technology overcomes some key challenging issues in the large-scale production of auxetic PU foams. 

Quasi Tri‐Axial Method for the Fabrication of Optimized Polyurethane Auxetic Foams

This paper describes the fabrication of polymeric auxetic foam using a quasi tri‐axial compression method. In this method, the conversion process is executed by applying a quasi tri‐axial compression

Developments on auxetic closed cell foam pressure vessel fabrications

Auxetic foam can have higher indentation resistance, better protection under impact and higher vibration damping than conventional foam. Unlike auxetic open cell foam, with established, commercially

Fabrication, characterization and analytical modeling of gradient auxetic closed cell foams

Auxetic (negative Poisson’s ratio) and gradient open cell foams have shown promise for their conformability and high impact energy absorption—useful in applications like protective equipment,

Fabrication of Auxetic Foam Sheets for Sports Applications

Auxetic materials have a negative Poisson's ratio, which can enhance other properties. Greater indentation resistance and energy absorption, as well as synclastic curvature, could lend auxetic

Bioinspired Multifunctional Cellular Plastics with a Negative Poisson’s Ratio for High Energy Dissipation

This method is environmentally friendly and capable of producing cellular plastics with various microstructures by harnessing the numerous morphologies of ice crystals, and shows a much higher energy dissipation capability compared to other materials with similar negative Poisson's ratios.

Preparing Polypropylene Auxetic Foam by a One‐Pot CO2 Foaming Process

At present, the direct preparation of polymer foam with negative Poisson ratio (auxetic foam) from nonpolar polymer resins is still a challenge. Herein, a one‐pot CO2 foaming method is established to

Effect of steam conversion on the cellular structure, Young’s modulus and negative Poisson’s ratio of closed-cell foam

Open-cell auxetic foams have shown potential for use in sporting and other protective equipment. Previous conversion methods for auxetic closed-cell foam used a bespoke pressure vessel. This work
