“…Furthermore, a large amount of water (∼90%) 18 contained inside the hydrogels leads to a poor mechanical strength. In this work, we use the supramolecular nanofibers formed by the self-assembly of sorbitol derivatives (DBS) 34 to prepare in situ reinforced PVA-TA hydrogels. Figure 1a shows the SEM image of the PVA-TA hydrogels without DBS nanofibers.…”

Novel conducting hydrogels (PVA-TA) with dual network structures were synthesized by the grafting reaction of tetraaniline (TA) into the main chains of poly(vinyl alcohol) and in situ reinforced by self-assembly of a sorbitol derivative as the gelator. The chemical structure of the PVA-TA hydrogels was characterized by using FT-IR and NMR. The mechanical strength of the PVA-TA hydrogels was strongly improved due to the presence of supramolecular nanofibers. For instance, the compressive and tensile strengths of supramolecular nanofiber-reinforced hydrogels were, respectively, 10 times and 5 times higher than those of PVA-TA hydrogels. Their storage modulus (G') and loss modulus (G″) were 5 times and 21 times higher than those of PVA-TA hydrogels, respectively. Cyclic voltammetry and conductivity measurements indicated that the electroactivity of reinforced hydrogels is not influenced by the presence of supramolecular nanofibers.

“…1a) is a compound with a strong ability of selfassembly in solvents. The self-assembly of DBS has been thoroughly investigated [35,36]. A common conclusion is that DBS self-assembles into nano-scaled supramolecular fibers and 3D network structures under the driving force of noncovalent interactions.…”

Gd 2 O 2 S:Tb, Dy phosphor were synthesized by co-precipitation method combined with solid-state reactions. The crystal structure and luminescent properties were investigated in this paper. It was confirmed that no new phase was introduced by the analysis of X-ray diffractions (XRD) and fluorescence spectroscopy. It was also illustrated that the lattice size was decreased by doping Dy 3þ ions. The results showed that the Dy 3þ coactivator had a remarkable influence on the spectral properties of the Gd 2 O 2 S:Tb phosphor and can be taken as rare earth ion detector to determine the micro-structure of phosphors. Especially the cross relaxation between Tb 3þ and Dy 3þ may take place to form the non-radiative energy transfer. Dy 3þ as the coactivator added in Gd 2 O 2 S:Tb could enhance the luminescence and not disturb its other primary properties. With Dy 3þ concentration increased, the intensity of 4 F 9/2 -H 13/2 transition at 578 nm was increased further and the emission of 5 D 4 -7 F J transition was highly improved to cause greener emission.
