Conductive hydrogels based on biopolymers have potential applications in the field of wearable devices, implantable devices, and human-machine interfaces due to their biocompatibility as well as conductivity. However, hydrogels are prone to water loss under dry atmospheres. In this paper, a biopolymer-based pressure sensor with water retention was designed. Xanthan gum (XG) and pullulan (P) were cross-linked with sodium trimetaphosphate (STMP) to prepare XG5-P-STMP, and polyethylene glycol with a molecular weight of 200 (PEG200) was added into hydrogels to improve moisture retention. The mechanical properties of the hydrogels were investigated by rheologic measurements such as time sweep, frequency sweep, and strain sweep. The results showed that the addition of PEG200 enhanced strength and moisture retention of the hydrogels, and high PEG200 content hindered the recovery property of the hydrogels. Furthermore, the XG5-P-PEG-STMP hydrogel with ionic conductivity and recoverability was explored as a pressure sensor, and the resistance change ratio exhibited repeatable profile. This work provides some valuable information for further applications of natural polysaccharides as intelligent flexible elections. © TBIS 2023. All rights reserved.

Although 2D transition-metal carbides (MXenes) are usually synthesized by selective etching and chemical vapor deposition approaches, they are limited by the slow reaction kinetics, resulting in their continuous production challenging. Here, we demonstrate a bubbling chemical vapor growth (BCVG) method to continuously produce Cl-terminated MXenes by the reaction of CH4 and TiCl4 chemical bubbles with titanium powder in a molten salt. In the molten reaction system, titanium powder would effectively react with TiCl4 to form highly active [TiCl6]y– with low Ti[sbnd]Cl bond dissociation energies. The multivalent [TiCl6]y– could efficiently incorporate the carbon species from CH4 to form [Ti6CCl18] clusters on the surface of bubbles in a low energy barrier, efficiently promoting the reaction kinetics. Subsequently, Cl-terminated MXenes were produced based on the following condensation reaction of [Ti6CCl18] clusters. The resultant MXene (Ti2CClx) exhibits an expanded structure with strong interfacial polarization between its basal planes and the polymer matrix, delivering a good electromagnetic wave absorption performance with a minimum reflection loss (RLmin) value of –52.2 dB at a thin thickness of 2.84 mm. © 2025 Elsevier Ltd

Herein,a novel TiO_(2)/CN heterojunction material has been prepared by one-step bubble template-assisted calcination to enhance the hydrogen storage capability of LiAlH_(4).The TEM,XPS and UPS analysis confirm that a heterostructure is formed between TiO_(2)and g-C3 N4 *** experimental findings indi-cate that the TiO_(2)/CN significantly enhances the dehydrogenation performance of LiAlH_(4).For instance,the LiAlH_(4)-7 wt%TiO_(2)/CN starts to dehydrogenize at 76℃(94℃ less than pure LiAlH_(4))and releases 6.5 wt%H2 at 200℃.Meanwhile,LiAlH_(4)-7 wt%TiO_(2)/CN releases 4.9 wt%H2 at 120℃ within 50 *** mech-anism analysis illustrates that AlTi3 N is formed in situ during *** density functional theory(DFT)calculation results reveal that the AlTi3 N can weaken the Al-H bonds in LiAlH_(4)through interfacial charge ***,the TiO_(2)/CN heterostructure creates an internal electric field that generates an electron-rich *** a result,the negative electron layer at one end of the TiO_(2)/CN heterojunction has an increased affinity for H,which enhances the dehydrogenation reaction of LiAlH_(4).Clearly,both the TiO_(2)/CN heterostructure and AlTi3 N contribute to the improvement of the dehydrogenation properties of LiAlH_(4).
