Efficient Self‐Cleaning and Anti‐Bacterial Behavior Realized by Hierarchical Structure in Hybrid Waterborne Polyurethane Coatings Containing Photocatalyst

open access: yesAdvanced Materials Interfaces, EarlyView.
Hybrid WPU coatings with a hierarchical structure are constructed by first directional freezing polymerization of degradable hydrogels with a vertical channel structure and then filling these channels with aqueous WPU solution containing carbon nitride (g‐C3N4) nanosheets.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Design of fibre reinforced PV concepts for building integrated applications [PDF]

open access: yes, 2009
Fibre reinforced polymers present an interesting encapsulation medium for PV-modules. Glass fibres can provide increased strength and stiffness to thin polymer layers overcoming the brittleness and limited deformability of glass-panes.
