Jeske, Madelyn P. published the artcileTwo-Photon Printing of Shape-Memory Microstructures and Metasurfaces via Radical-Mediated Thiol-Vinyl Hydrothiolation, Synthetic Route of 7575-23-7, the main research area is photon printing shape memory metasurface radical thiol vinyl hydrothiolation.
Shape-memory resists capable of high-resolution curing into arbitrarily designed structures are increasingly demanded for soft robotics, optical sensors, microscale manufacturing, and biomedicine. Amorphous, shape-memory thiol-vinyl networks are printed using two-photon polymerization (2PP) curing of a simple resin formulated with com. available reagents. The ability to print high-resolution feature sizes down to 200 nm is attributed to the use of radical-mediated, thiol-vinyl step-growth polymerization that quickly crosslinks the resin, limiting diffusive transport. The thermomech. behavior of the 2PP-cured material analyzed in compression, tension, and three-point bending is similar to the behavior of the UV-polymerized samples. To demonstrate the ability to design, field, and test 4D responsive microstructures, an array of nine springs with coil diameters of 330μm is printed. Following compressive shape-fixing, printed arrays can release 11μJ of stored elastic strain energy when reheated. Further, a new concept of dichroic-memory of a metamaterial device is demonstrated by printing a twisted woodpile structure with CD as characterized by Mueller Matrix ellipsometry. The results of this study demonstrate how combining high-resolution 2PP curing with stimuli-responsive mol. architectures can further the engineering of responsive microstructures and metamaterials.
