Analogous to the morphological and functional features of cactus root, a novel cactus root-inspired material (CRIM) was fabricated by integrating cellulose fibers, microparticles, and agarose-based cryogels. Without undergoing sophisticated chemical synthesis or surface modification, the CRIM exhibited efficient water absorption and retention ability with high structural stability. 82% of the total water absorption capacity was recovered within 1 min, with a swelling rate nearly 930-fold faster than the evaporation rate, while only about 17% of the length extension occurred. Given that efficient water absorption and storage without physical change is crucial to the design and fabrication of water management devices, the CRIM is a promising material for various applications, including cosmetics or healthcare products, functional fabrics, and drug delivery devices.

受仙人掌根启发的快速高效吸水材料
类似于仙人掌根的形态和功能特征，通过整合纤维素纤维、微粒和基于琼脂糖的冷冻凝胶制造了一种新型仙人掌根启发材料 (CRIM)。无需经过复杂的化学合成或表面改性，CRIM 就表现出高效的吸水和保持能力，具有高结构稳定性。82%的总吸水能力在1分钟内恢复，膨胀速度比蒸发速度快近930倍，而长度只有17%左右发生延伸。鉴于没有物理变化的高效吸水和储存对于水管理设备的设计和制造至关重要，因此 CRIM 是一种很有前途的材料，可用于各种应用，包括化妆品或保健产品、功能性织物、
