Summary: In this study, PVA/GO composites were prepared using the freezing-thawing method, with investigations on their morphology, chemical structure, viscoelastic properties, and absorption of a cationic dye. The results showed that increasing the concentration of GO led to significant improvements in the properties of the composites, particularly in terms of absorption capacity. A correlation between absorption, swelling, and viscoelastic properties was proposed for the PVA/GO composites.

Summary: An annealed PPy/PVA film was successfully applied to the surface of ZnCo2O4 nanorods, significantly improving the electrochemical performance of the nanocomposites. The inclusion of PVA played a crucial role in inhibiting aggregation, ensuring firm adhesion, and suppressing volume expansion during cycling, leading to a high reversible capacity of 1020 mA h g(-1) for 300 cycles at a current density of 500 mA g(-1). Overall, the study proposes PPy/PVA composites as a promising strategy to enhance the stability and rate performance of ZnCo2O4 for lithium-ion batteries.

Summary: Graphene is widely used in heat dissipation due to its high in-plane thermal conductivity and excellent mechanical properties. However, its poor cross-plane thermal conductivity limits its use in certain electronic applications. In this study, fluorinated graphene oxide (FG) with high thermal conductivity is prepared by grafting F atoms onto the surface of graphene oxide using poly(vinylidene fluoride) as a fluorine source. By avoiding the use of dangerous substances such as HF and F-2, FG can be synthesized effectively. The FG is then used to create a FG/PVA composite film with enhanced thermal conductivity, suitable for thermal management in flexible electronic devices.

Summary: Poly(vinyl alcohol) (PVA)/silver aluminium oxide (AgAlO2)@reduced graphene oxide (rGO) nanocomposites (NCs) were fabricated as flexible supercapacitor electrodes using a solution casting approach. The NCs exhibited excellent electrochemical performance, wide operating potential windows, high specific capacitance, energy density, and power density, as well as negligible equivalent series resistance and charge transfer resistance. The addition of AgAlO2 NPs in the NCs showed better specific capacitance, providing a new approach for fabricating supercapacitor electrodes.

Summary: New anion-exchange membranes based on poly(benzimidazolium-imide) containing triazolium groups were prepared using click chemistry for triazolium groups and cross-linking simultaneously. Two different cross-linked membranes with a hydrophilic cross-linker (Q-CLP1) and a hydrophobic cross-linker (Q-CLP2) were tested for mechanical properties. Q-CLP1 showed higher tensile stress due to the rigidity of the aromatic cross-linker, while Q-CLP2 had more fixability and tensile strain due to the aliphatic cross-linker.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
