“…By contrast, the pores are not evident for the Con-CMC, due to the formation of precipitates insides the pores. These precipitates arise from a large amount of KAc salt solid residue after freeze-drying. , Based on Fourier transform infrared (FTIR) spectrometer measurements (Figure c), the bands of Dil-CMC hydrogel electrolyte at approximately 3272, 1553, 1436, and 1028 cm –1 correspond to – OH stretching, – COO – asymmetric stretching, – COO – symmetric stretching, and C–O–C bending, respectively. , For the bands from – COO – , there existed a difference in the band position for two hydrogel electrolytes, due to much higher content of Ac – ions in the Con-CMC hydrogel electrolyte. , Besides, owing to the strong binding between Ac – ions and water molecules, the – OH stretching band of Con-CMC hydrogel electrolyte moved to a higher wavenumber. , …”

“…During the freezing process, the space occupied by CMC chains was significantly reduced due to the freezing of water molecules into ice crystals, thereby resulting in an increase in the local concentration of CMC. 29 This could force CMC chains to aggregate, contributing to enhanced hydrogen bonding and associated cross-linking. 31 After four F-T cycles, a strong and tough CMC hydrogel was produced.…”

Aqueous zinc-ion batteries are limited by poor Zn stripping/ plating reversibility. Not only can hydrogel electrolytes address this issue, but also they are suitable for constructing flexible batteries. However, there exists a contradiction between the mechanical strength and the ionic conductivity for hydrogel electrolytes. Herein, high-concentration kosmotropic ions are introduced into the cellulose hydrogel electrolyte to take advantage of the salting-out effect. This can significantly improve both the mechanical strength and ionic conductivity. Additionally, the obtained cellulose hydrogel electrolyte (denoted as Con-CMC) has strong adhesion, a wide electrochemical stability window, and good water retaining ability. The Con-CMC is also found to accelerate the desolvation process, improve Zn deposition kinetics, promote Zn deposition along the (002) plane, and suppress parasitic reactions. Accordingly, the Zn/Zn cell with Con-CMC demonstrates dendrite-free behavior with prolonged lifespan and can endure extremely large areal capacity of 25 mAh cm −2 . The Con-CMC also enables a large average Coulombic efficiency of 99.54% over 500 cycles for the Zn/Cu cell. Furthermore, the assembled pouch-type Zn/polyaniline full battery provides great rate capability, superior cyclability (even with limited Zn anode excess), a slow self-discharge rate, and outstanding affordability to external forces. Overall, this work extends our knowledge of the rational design of hydrogel electrolytes.

Cellulose nanopaper has shown great potential in diverse fields including optoelectronic devices, food packaging, biomedical application, and so forth, owing to their various advantages such as good flexibility, tunable light transmittance, high thermal stability, low thermal expansion coefficient, and superior mechanical properties. Herein, recent progress on the fabrication and applications of cellulose nanopaper is summarized and discussed based on the analyses of the latest studies. We begin with a brief introduction of the three types of nanocellulose: cellulose nanocrystals, cellulose nanofibrils and bacterial cellulose, recapitulating their differences in preparation and properties. Then, the main preparation methods of cellulose nanopaper including filtration method and casting method as well as the newly developed technology are systematically elaborated and compared. Furthermore, the advanced applications of cellulose nanopaper including energy storage, electronic devices, water treatment, and high-performance packaging materials were highlighted. Finally, the prospects and ongoing challenges of cellulose nanopaper were summarized.

To solve the problems of low mechanical properties and poor coagulation effect of soluble hemostatic dressings, a new type of soluble hemostatic fabric with three-dimensional knitted structure is proposed in this paper. Three-dimensional knitted fabrics had good extension and porous structure. This three-dimensional soluble knitted fabric can be used for skin wounds clotting and healing. This paper mainly studied the influence of structural thickness on the performance of three-dimensional knitted dressings. Characterization analysis showed that three-dimensional knitted soluble hemostatic dressings had appropriate porosity and water vapor transmission rate (WVTR), and the fabric with the maximum thickness had good elongation (70.04%) and a very low blood clotting index (BCI) (11.18%). This suggests the potential application for soluble three-dimensional knitted structure fabric on skin wound hemostasis.
