“…This indicates that the alkali acid treatment removes hemicellulose, lignin, and pectin from the surface of the bamboo powder fibers and that the presence of the modified microprimary fibers results in a larger specific surface area, which facilitates contact between the bamboo fibers and sodium alginate. The formation of grooves on the surface of the fibers creates a strong capillary effect, which facilitates the infiltration of bamboo fibers with the polymer matrix and enhances the interaction between them . At the same time, the fundamental component of the fiber, the micro protofiber, forms microfibrillated bundles along the axial direction, which have an excellent strengthening effect on the mechanical properties of the composite when fused with the polymer .…”

Modified bamboo fiber (BF), sodium alginate (SA), and NaCl were used as the raw materials. At first, the modified bamboo fiber (BF) was obtained through the surface modification of the bamboo fiber. Then, BF and SA were dissolved in a solution, and CaCl2 was used for molding. Finally, the formed hydrogel was soaked in a NaCl solution to prepare ion-conducting hydrogels with different bamboo fiber contents. The effects of BF on the mechanical properties, swelling properties, and microstructure of the composite hydrogel were investigated. The results show that when the content of modified bamboo fiber is 1.5%, the mechanical properties of the hydrogel are improved, the elongation at break reaches 340%, and the tensile strength reaches 1.58 MPa. The swelling rate of the composite hydrogel decreased to 535%. The study revealed that the conductivity of the mixed conductive hydrogels increased immediately with the concentration of the salt solution. Additionally, the conductivity of the composite conductive hydrogels showed a significant boost with the rise of the BF content under identical salt solution concentrations, which reached a conductivity value of 4.94 S/m. The optimized SA/BF conductive hydrogel was used to create a strain sensor for monitoring the pressure motion. This sensor achieved a short response time and high reproducibility for pressure. It has broad application prospects in wearable electronic devices.

This study examines the effect of a short term rotation on a system of constant volume. Adsorption of CO2 is performed on Activated Carbon (AC) at 281, 293 and 298 K with a special designed device that allows rotation. The adsorption isotherms were conducted up to 10 bar for both No Rotational (NoROT) and Rotational (ROT) cases. The ROT case refers to 60 s of rotation at 5000 rpm. The experimental results were fitted to Langmuir as well as to Dubinin–Astakhov (D–A) models with the latter presenting the best fit. A detailed thermodynamic analysis is performed in order to quantify the overall contribution of the rotation on gas adsorption compared to static case. For the ROT case, the maximum amount adsorbed (q max) is by 12 % higher than the NoROT counterpart, while a decrease in chemical potential as surface loading is increased, indicates that the process after rotation is entropy driven. The outcome of this work suggests that rotation enables gas molecules to access previously inaccessible sites, thus gaining more vacancies due to better rearrangement of the adsorbed CO2 molecules.
