In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.
In conclusion, plastic gratings have revolutionized the way we approach walkway construction and maintenance. Their robustness, resistance to corrosion, lightweight, non-slip surface, and eco-friendly attributes make them a preferred choice for various industries and environments. As technology continues to advance, it's likely that plastic gratings will play an even more significant role in creating safer and more sustainable walkways for the future.
