Surface Modification of Fluorine‐Free Superhydrophobic Materials with (Ultra‐)Thin TiO2 Layers
Advanced Engineering Materials, EarlyView.Significant changes in wettability, with a reduction of 60o in the water conduct angle, are reported via the surface modification of fluorine‐free superhydrophobic thin films, prepared by aerosol‐assisted chemical vapor deposition, after coating a 4 nm layer of titanium dioxide on the surface using atomic layer deposition.

Advanced Engineering Materials, EarlyView.A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Advanced Engineering Materials, EarlyView.A shape‐morphing, porous polyurethane film combines passive radiative cooling with folding to deliver multilevel heating‐and‐cooling control. High solar reflectance and midinfrared emissivity keep surfaces up to 3.5 °C cooler in direct sunlight, while photothermal triggering folds the film to absorb solar heat.
