“…The Δ W r induces the initiation of the p-cracks on the PEDOT:PSS film after the prestrain release. If these cracks are homogeneously formed on the PEDOT:PSS film (e.g., the formation of these cracks is independent of the interfacial bonding between the PEDOT:PSS film and the PDMS slab), a channel crack can be developed on the PEDOT:PSS film . The area ratio ( P p,r ) of p-cracks in the PEDOT:PSS film, which was transferred onto the PDMS slab, can be expressed as follows P normalp , normalr = W normalp , 0 ε p ( ν normals − ν normalf ) W normalp , 0 ( 1 + ν normals ε normalp ) = ε p ( ν normals − ν normalf ) 1 + ν s ε p where W p,0 (1 + ν s ε p ) represents the width of the PDMS slab after the prestrain release.…”

“…However, the heterogeneous nature of crack initiation and development in the PEDOT:PSS film, attributed to the presence of defects, should be taken into account as constraining by the PDMS slab during the film relaxation, thereby differing from the channel crack described by eq 5. 32,33 The consideration of the heterogeneous case allows for the derivation of a solution in the following manner. where k is a constant determined by the presence of cracked structures, referring to the possibility of crack development to heterogeneous independent units.…”

The recent advancement of stretchable photoelectronics has catalyzed revolutionary transformations in various cutting-edge fields. However, the stretchable transparent electrodes (STEs), which are vital components ensuring signal conduction in stretchable photoelectronics, pose a challenge due to the rigid and fragile nature of conventional conductive materials. In this study, we demonstrated a prestrain transfer technique for fabricating STEs using PEDOT:PSS. The resulting STEs achieved a sheet resistance of approximately 50 Ω/sq by leveraging the benefits of methanesulfonic acid treatment and incorporating a carbon-nanotube blend in PEDOT:PSS. The fabricated STEs exhibited exceptional transparency exceeding 90% and remarkable stability over 1000 stretching cycles without degradation in conductance. An in situ investigation was conducted to visualize the deformation of the PEDOT:PSS film and its association with the electrical ductility of the STEs. The prestrain transfer was found to induce kirigami-type cracks and out-of-plane microwrinkles in the PEDOT:PSS film. These structures effectively alleviate stress concentration and compensate for strain during stretching loading, thereby imparting enhanced stretchability and electrical ductility to the STEs. However, once the stretching strain exceeded the prestrain threshold, numerous microcracks emerged on the PEDOT:PSS film, leading to electrical failure of the STEs due to a significant rise in resistance. The incorporation of carbon nanotubes was demonstrated to modulate crack structures, thereby enhancing both the mechanical and electrical ductility of STEs. Additionally, a theoretical model was proposed to quantitatively analyze the morphological evolutions in the PEDOT:PSS film while establishing its correlation with the mechanical and electrical properties of the STEs. The parameters associated with crack structures, sensitivity of resistance to cracks, and tensile limit of PEDOT:PSS were extracted to elucidate the underlying mechanisms of prestrain engineering on the electrical ductility and failure of the STEs. The present results offer guidance for experimental and theoretical approaches for optimizing the fabrication process of stretchable electronics.

Biodegradable stents are the most promising alternatives for the treatment of cardiovascular disease nowadays, and the strategy of preparing functional coatings on the surface is highly anticipated for addressing adverse effects such as in-stent restenosis and stent thrombosis. Yet, inadequate mechanical stability and biomultifunctionality limit their clinical application. In this study, we developed a multicross-linking hydrogel on the polylactic acid substrates by dip coating that boasts impressive antithrombotic ability, antibacterial capability, mechanical stability, and self-healing ability. Gelatin methacryloyl, carboxymethyl chitosan, and oxidized sodium alginate construct a double-cross-linking hydrogel through the dynamic Schiff base chemical and in situ blue initiation reaction. Inspired by the adhesion mechanism employed by mussels, a triple-cross-linked hydrogel is formed with the addition of tannic acid to increase the adhesion and antibiofouling properties. The strength and hydrophilicity of hydrogel coating are regulated by changing the composition ratio and cross-linking degree. It has been demonstrated in tests in vitro that the hydrogel coating significantly reduces the adhesion of proteins, MC3T3-E1 cells, platelets, and bacteria by 85% and minimizes the formation of blood clots. The hydrogel coating also exhibits excellent antimicrobial in vitro and antiinflammatory properties in vivo, indicating its potential value in vascular intervention and other biomedical fields.

In the dynamic landscape of industrial processes, membrane technology offers a paradigm shift beyond energyintensive separation techniques, exemplifying a progressive leap toward sustainability. In this regard, highly flexible and uniform poly(3,4-ethylenedioxythiophene)polystyrenesulfonate (PE-DOT:PSS)-engineered membranes at a reduced thickness have been fabricated on track-etched poly(ethylene terephthalate) (PET) substrates. The membranes were functionalized and embedded with platinum nanoparticles (Pt NPs) having a higher affinity toward H 2 gas. The materials and fabricated membranes were characterized by using high-resolution transmission electron microscopy (HRTEM) and field emission scanning electron microscopy (FESEM) techniques for morphological and structural analysis. FTIR and Raman characterizations were performed to study the characteristic bonds. The uniformity and quantification of Pt nanoparticle binding were tested through inductively coupled plasma mass spectrometry (ICP−MS) studies and FESEM with EDS mapping. The gas separation performance was studied using H 2 , N 2 , and CO 2 gases in pure and mixed (H 2 /CO 2 in 50:50) states. It was observed that the modified membrane showed a 116% increment in H 2 permeability and 82 and 107% increment in H 2 /CO 2 and H 2 /N 2 selectivity values with pure gas, while a 121% increment in H 2 permeability and 156% increment in H 2 /CO 2 selectivity using mixed gas. The separation performance in pure and mixed gas states with repeated experiments conspicuously highlighted their prospective viability as prime contenders for gas separation applications.
