 Abstract porous materials have been widely used for passive energy absorption in various applications including aerospace systems, automotive vehicles, and electronic products, due to their ability to absorb energy and reduce noise. However, these materials often lack sufficient mechanical strength, making them unsuitable for shock-absorbing structures. To address this issue, researchers developed a new type of porous material called auxetic foam, which features a highly ordered honeycomb pattern on its surface. This pattern was created using a non-solvent process, allowing for precise control over the size and shape of the pattern. The auxetic foam also exhibited improved shock absorption capabilities, reducing impact force by up to 34%. Additionally, the auxetic foam's mechanical strength was greatly increased, making it suitable for use in shock-absorbing structures.
