Abstract: The present disclosure provides for porous polymer materials that include an ordered array of voids separated by a polymer framework. The porous polymer material can have a recovery state where the voids are in an uncollapsed state and iridescent color, and a deformed state having voids in a collapsed state that is non-iridescent or substantially transparent. The materials can have regions of both states simultaneously. Also described are methods for fabricating a polymer material as above, as well as chromogenic sensors including the polymer material. The sensors can have hidden anti-counterfeiting patterns, hydrophobic/oleophobic properties, and chromogenic transformation can be triggered by various stimuli such as solid target compounds, light energy, and more.

Abstract: Provided herein are materials, methods of making materials, and methods of use, wherein the materials have switchable adhesive properties. Materials of the present disclosure can reversibly change coloration in conjunction with the changing adhesive state. The films, made from a porous polymer material, can be reversibly changed from a smooth state to a rough state, allowing for reversible and tunable gripping and/or adhesive properties.

Abstract: Described herein are various embodiments of a valve that may be opened and closed using a thixotropic or “stress yield” material, or other material that temporarily changes phase upon application of energy to the material. More particularly, some embodiments may include a valve that is opened and closed using a granular gel that is a temporary phase change material.
