Non-monotonic Information and Shape Evolution of Polymers Enabled by Spatially Programmed Crystallization and Melting

“…The mechanical stability of polymer film is crucial for their application. 28 We measured the mechanical property of the samples with different t ir values (Figure S5a). The results show that with the extension of irradiation time, the tensile strength of the material decreases slightly and the elongation at break increases, which may be due to the decrease of X c of the samples.…”

Stretchable, Washable, and Anti-Ultraviolet i-Textile-Based Wearable Device for Motion Monitoring

“…Ionogel is a type of conductive material consisting of a three-dimensional porous polymer structure infused with ion conductors. , It exhibits exceptional flexibility, absorption, conductivity, and stability, making it a versatile material with applications in various fields. − Ionogels can be prepared through a straightforward UV polymerization process, and their properties can be tailored by manipulating their composition, cross-linking degree, and pore structure. For instance, the introduction of specific waterproof functional groups enables the development of ionogels with superior water resistance. − The presence of amino or hydroxyl functional groups in the polymer facilitates the adsorption of the ionogel on diverse substrate surfaces. , Taking into account the adhesion properties of the ionogel, an ionic textile (i-textile) has been created by immersing the textile in an ionogel precursor .…”
