Amphibious superlyophobic shape memory arrays with tunable wettability in both air and water

Fully Biodegradable Packaging Films for Fresh Food Storage Based on Oil‐Infused Bacterial Cellulose

“…[30] The intimacy between oil and solid is dynamically tunable to make the oil stably held in the solid during operation, while being fully removable upon chemical stimuli after usage. [31,32] These characteristics align well with the requirements of cellulose-based packaging materials.…”

Bioinspired magnetism-responsive hybrid microstructures with dynamic switching toward liquid droplet rolling states

“…[11][12][13][14] Recently, intelligent surfaces with switchable isotropic/anisotropic droplet rolling states have been extensively reported, which are expected to overcome the limitation rooted in pre-vious fixed surfaces. [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] For example, Wang et al reported a switchable surface with vertically and temporarily inclined microarrays using a shape memory polymer (SMP) for droplet transport and information storage; 22 Li et al prepared a SMPbased microcone array doped with iron powder particles for multifunctional droplet manipulation and could readily switch between vertical and curved states. 26 Despite the advances in switching between isotropic and anisotropic rolling states using these strategies, dynamic liquid droplet control with fast response and no loss still remains a challenge.…”

“…26 Despite the advances in switching between isotropic and anisotropic rolling states using these strategies, dynamic liquid droplet control with fast response and no loss still remains a challenge. Most of the reported switchable surfaces require specific SMP materials to shift the surface morphology via their intrinsic shape memory property, such as polyurethane, [16][17][18][19][20] epoxy resin, [21][22][23][24][25][26][27][28][29][30] azobenzene polymers, 31 etc., which are usually assisted by heating-applying external force-cooling [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] or light radiation 31 and are unable to rapidly switch the surface state in real time. As a result, the materials preparation and regulation are rather complicated and high-cost.…”

“…As a result, the materials preparation and regulation are rather complicated and high-cost. [16][17][18][19][20]31 Moreover, most SMP materials are in the rigid form without flexibility at room temperature, [21][22][23][24][25][26][27][28][29][30] which also severely limit their further utility in smart wearable devices.…”
