Design and preparation of a biomimetic DEA coating featuring repair and buffering capabilities (IMAGE)
Caption
Inspired by the structure of human enamel, a biomimetic coating with enhanced viscoelasticity was constructed layer by layer. The underlying amylose hydrogel serves as both a buffering layer and a self-repairing filler. Using multiple spin-coating processes, TiO2@LA combined with CNTs was applied, followed by hot pressing to create a durable, wear-resistant superhydrophobic surface atop the hydrogel. This layered structure effectively disperses energy under impact loads and prevents crack propagation. Its exceptional mechanical durability and corrosion resistance make it highly promising for protecting oil pipelines against erosion and corrosion.
