A stimuli-responsive gel impregnated surface with switchable lipophilic/oleophobic properties

Abstract

A stimuli-responsive gel impregnated surface with switchable lipophilic/oleophobic properties driven by the swelling effect of a hydrogel with controllable morphology.

A highly controlled fabrication of porous anodic aluminium oxide surface with versatile features by spatial thermo-anodization

“…One of the essential criteria for a coating technology to be used in aerospace engineering, is the surface icephobicity [36][37][38][39][40]. Alongside with the recent anti-icing perspectives by using heated surface [41], textured surfaces [42][43][44][45], latest approach of liquid infused surface present a low cost and programmable strategy to distinguish itself from above [46][47][48]. Here, we develop a hybrid strategy by applying a silanization layer to seal the anodized porous surface (Fig.…”

Smart Surfaces with Tunable Wettability

“…Most of the external stimulus changes the chemical composition of the substrate; however, changing the surface structures also produces a change in the surface wettability. Various research groups have demonstrated the mechanical stress-responsive tunable wettability using elastic or gel materials [68][69][70][71][72][73][74][75]. Poly(tetrafluoroethylene) PTFE is the most common 21st Century Surface Science -a Handbook hydrophobic material, and Teflon tape, made with PTFE crystals, has been widely used to tune the wetting behavior by applying mechanical strain.…”

Flexible Strain Sensor Enabled by Carbon Nanotubes‐Decorated Electrospun TPU Membrane for Human Motion Monitoring

“…As a kind of emerging nanomaterials, CNTs are also widely used in many fields [60][61][62][63][64] . Selecting suitable materials to prepare various sensors has become the research focus of scholars at home and abroad [65][66][67][68][69][70][71] . Li et al [72] prepared a flexible sensor with the wide monitoring range and ultralow detection limit by ultrasonically anchoring CNTs to TPU electrospun membrane.…”

[65][66][67][68][69][70][71] Li et al [72] prepared a flexible sensor with a wide monitoring range and ultralow detection limit by ultrasonically anchoring CNTs to TPU electrospun membrane. However, it also shows the disadvantage of a low sensitivity limit, which is less desirable in a condition requiring high sensitivity.…”
