Programming Reversibly Self‐Folding Origami with Micropatterned Photo‐Crosslinkable Polymer Trilayers
Jun-Hee Na,Arthur A. Evans,Jinhye Bae,Maria C. Chiappelli,Christian D. Santangelo,Robert J. Lang,Thomas C. Hull,Ryan C. Hayward +7 more
TL;DR: Self-folding microscale origami patterns are demonstrated in polymer films with control over mountain/valley assignments and fold angles using trilayers of photo-crosslinkable copolymers with a temperature-sensitive hydrogel as the middle layer.
Journal ArticleDOI
Photonic Multilayer Sensors from Photo‐Crosslinkable Polymer Films
TL;DR: Layer thicknesses and copolymer chemistries are chosen to provide robust colorimetric temperature sensors that cover nearly the full visible spectrum.
Journal ArticleDOI
Gelation of Copolymers with Pendent Benzophenone Photo-Cross-Linkers
TL;DR: The placement of the hydrogen species most susceptible to abstraction by triplet benzophenone is found to greatly influence gelation efficiency, since radical generation on the polymer backbone typically increases the probability of dislinking events, while hydrogen abstraction pendent to the copolymer backbone tends to enhance cross-linking.
Journal ArticleDOI
Photocrosslinkable Nanocomposite Multilayers for Responsive 1D Photonic Crystals
TL;DR: In this paper, a straightforward method to increase the refractive index of photocrosslinkable polymers by incorporation of high index inorganic nanoparticles is demonstrated and shown to enhance the reflection efficiency of thermochromic 1D photonic multilayers.
PatentDOI
Photonic polymer multilayers for colorimetric radiation sensing
TL;DR: A radiation sensor as mentioned in this paper consists of a substrate and a polymer multilayer film including alternating layers of a high refractive index polymer and a low-refractive index polymeric polymer.
