Summary: Covalent adaptive networks combine the advantages of cross-linked elastomers and dynamic bonding in a single system. A simple one-pot method to prepare thiol-ene elastomers that exhibit reversible photoinduced switching from an elastomeric gel to fluid state is demonstrated. This behavior can be generalized to different composition and chemistries and allows for self-healing, remolding, and reversible adhesion.

Summary: In this study, we employed a high-throughput screening strategy to rapidly identify a biocompatible bone adhesive with high bond strength. Through thiol-ene click chemistry, a library of polymers was synthesized and a copolymer (1-S2-FT01) composed of TATATO and PETMP was identified as the most suitable candidate. This copolymer exhibited favorable mechanical properties, supported hMSC adhesion, adhered to bone tissue with similar strength to commercially available bone glues, and facilitated osteogenic differentiation of hMSCs and attachment of polymer scaffolds to bone tissue, making it an ideal alternative bone adhesive for orthopedic surgery.

Summary: The physicochemical properties of poly(diallyldimethylammonium chloride) (poly (DADMAC)) and its copolymer with zwitterionic monomer 2-(diallyl(methyl)ammonio) acetate (DAMA) were studied in aqueous solutions with different sizes of ions. The results showed that larger halogen ions facilitated the condensation of bulky anions on the polyelectrolyte chain, leading to a collapse of the poly(DADMAC) coil in the presence of iodine ions. However, introducing DAMA units into the polymer chain improved the solubility of the resulting copolymer (poly (DADMAC-co-DAMA)) in aqueous solutions with iodine ions.

Summary: In this study, poly (vinylidene fluoride-hexafluoropropylene) copolymer films with hexafluoropropylene content 8.3 mol% were obtained by low-temperature crystallization from various solvents. The films mainly crystallized in the alpha-phase, with the degree of crystallinity influenced by the solvent used. IR spectroscopic data showed enrichment of T(3)GT(3)G(-) isomers in the amorphous phase, leading to an increase in high-voltage conductivity. Despite crystallizing mainly in the nonpolar alpha-phase, domain structures were observed in the films using piezo force microscopy.

Summary: Polymer films doped with different porphyrins show variations in absorption and fluorescence spectra due to differences in the structuring and composition of the rotational isomers in the polymer chains. Crystallization of tetraphenylporphyrin (TPP) doped films involves mixtures of alpha- and gamma-phases with TGTG(-) and T(3)GT(3)G(-) conformations, respectively. The introduction of TPP during film formation leads to increased conductivity and the presence of hysteresis phenomena in local piezoelectric measurements.

Summary: Single crystals of [K1-x(NH4)(x)](3)H(SO4)(2) (x >= 0.57) grown in the K3H(SO4)(2)(NH4)(3)H(SO4)(2)-H2O water-salt system were studied. The atomic structure, including H atoms, was determined at room temperature using X-ray structural analysis. [K1-x(NH4)(x)](3)H(SO4)(2) (x >= 0.57) crystals exhibit trigonal symmetry and disordered hydrogen-bond networks similar to the high-temperature phases of K3H(SO4)(2), (NH4)(3)H(SO4)(2), and other superprotonic compounds M3H(AO(4))(2). Impedance measurements on single crystals revealed the high conductivity characteristic of superprotonic phases. Anisotropy of the crystal conductivity was detected using impedance spectroscopy and atomic force microscopy. Additionally, a qualitative correlation between bulk and local conductivity of samples with the same composition and orientation at room temperature was observed, attributed to the peculiarities of their crystal structure.

Summary: This article mainly introduces the low power consumption of electrochromism in actively shaded windows and mirrors, as well as its flexibility for use in wearable devices. By combining conductive and electrochromic ionic liquid-doped poly-(3,4-ethylenedioxythiophene) polystyrene sulfonate with poly-(vinyl alcohol)-based electrolyte, complete electrochromic devices are formed. These devices demonstrate a transmission change of 15% and a reflectance change of 25% for opaque reflective applications, with a switching time of less than 7 seconds under 30% strain. The devices also show stability under both electrochemical and mechanical strain cycling, and a passive matrix display exhibits addressability and low cross-talk under strain. The comparable optical performance to flexible electrochromics and higher deformability make them attractive for wearable, biometric monitoring, and robotic skin devices.
