Carbon Nanotubes and Silica@polyaniline Core-Shell Particles Synergistically Enhance the Toughness and Electrical Conductivity in Hydrophobic Associated Hydrogels

Yuhui Xie et al.

Summary: This article introduces a novel carboxylated carbon nanotube (MWCNT-COOH)-embedded P(AM/LMA)/SiO2@PANI hydrogel, which benefits from a double-network structure and exhibits high tensile strength, super stretchability, and excellent strain sensitivity. MWCNT-COOH not only improves the electrical conductivity but also enhances the mechanical properties of the hydrogel. Therefore, the integration of MWCNT-COOH and SiO2@PANI-based hydrogel strain sensors will have broad applications in various fields.

Fully physically crosslinked organohydrogel with ultrastretchability, transparency, freezing-tolerant, self-healing, and adhesion properties for strain sensor

Feng Ji et al.

Summary: Conductive hydrogels with stretchability, transparency, anti-freezing, self-healing, and adhesion properties are in high demand for intelligent wearable devices. A novel multifunctional organohydrogel based on noncovalent intermolecular interactions was developed by polymerizing hydroxyethyl acrylamide (HEAA) in LiCl cryoprotectant/water solution. The gel formation was driven by hydrogen bonding interactions. The organohydrogel exhibited good conductivity, anti-freezing properties, self-healing, and adhesion due to the composition of LiCl and cryoprotectant. Based on this organohydrogel, a strain sensor for detecting human movements in a wide temperature range was successfully prepared.

Graphene Oxide-Carbamoylated Chitosan Hydrogels with Tunable Mechanical Properties for Biological Applications

Ratnika Gupta et al.

Summary: This study focuses on the formation of a nanocomposite hydrogel by adding graphene oxide (GO) nanofillers to carbamoylated chitosan (CH). The influences of chitosan molecular weight (Mw) and GO loading concentrations on hydrogel properties are studied. The results show that the physical properties of the hydrogels can be tuned by adjusting both the GO concentration and the Mw of chitosan. Rheological characterization reveals improvements in the mechanical properties of the synthesized CH-GO hydrogels with an increase in Mw and GO concentration. Human retinal pigmented epithelial-1 (RPE-1) cells exhibit good compatibility with the hydrogel scaffolds, with cell viability, adhesion, and spreading dependent on the Mw of chitosan and GO loading.

A moisture self-regenerative, ultra-low temperature anti-freezing and self-adhesive polyvinyl alcohol/polyacrylamide/CaCl2/MXene ionotronics hydrogel for bionic skin strain sensor

Wenwu Peng et al.

Summary: Ignited by the concept of bionics, hydrogel-based bionic skin sensors have been widely used in health monitoring, robots, implantable prostheses, and human-machine interfaces. However, there are still challenges to be solved, such as water evaporation and the defects of single conductive mechanism. In this study, a polyvinyl alcohol/polyacrylamide/CaCl2/MXene (PPCM) ionotronics hydrogel was prepared, which showed moisture self-regenerative, highly sensitive, ultra-low temperature anti-freezing, and self-adhesive features. The addition of CaCl2 offered the PPCM hydrogel long-term water retention, ensuring the stability of the hydrogel-based sensor.

Investigation on frost heaving stress (FHS) of porous cement concrete exposed to freeze-thaw cycles

Jun Chen et al.

Summary: Frost Heaving Stress (FHS) is a main cause of freeze-thaw (FT) damage in porous cement concrete. A customized measurement device was used to study the influence of curing time, air void, saturation degree, and freeze-thaw cycles on FHS evolution. The results showed that FHS evolution can be divided into three stages, and the increase of saturation degree leads to the growth of FHS. FHS does not completely dissipate in the thawing process.

Summary: This paper investigates the effect of adding superabsorbent polymers (SAP) and United expansion agent (UEA) on the shrinkage and tensile properties of ultra-high performance engineered cementitious composites (UHP-ECC). The results show that the incorporation of SAP and UEA effectively mitigates the autogenous shrinkage of UHP-ECC, while the drying shrinkage shows the opposite trend. Furthermore, the inclusion of SAP improves the tensile ductility of UHP-ECC, but decreases the tensile strength.

Using modified nano-silica to prevent bubble Ostwald ripening under low atmospheric pressure: From liquid foam to air-entrained cement mortar

Zhenxing Du et al.

Summary: This study investigates the use of modified partially hydrophobic nano-silica particles to stabilize air bubbles in cement mortar under low atmospheric pressure. The results show that low atmospheric pressure has a limited effect on the distribution of bubble sizes, but accelerates the process of bubble ripening, leading to larger bubble sizes and decreased air content. The modified nano-silica effectively stabilizes the bubbles and prevents their ripening. This study provides a feasible method to stabilize air bubbles and improve the air-void structure of concrete in extreme environments.
