Summary: Self-healable polymers are promising intelligent materials that can repair physical damage autonomously, extending their lifetime and reducing maintenance costs. In this study, a series of polymers with switching phase and healing accelerator properties were synthesized and blended with poly(vinyl alcohol). The resulting blend demonstrated good self-healing behavior and hydrothermal-response shape memory effect.

Summary: In this study, a kappa-carrageenan-grafted-poly(acrylamide)/Fe3O4-GO adsorbent was successfully prepared and characterized. The results showed that the adsorbent exhibited superparamagnetic behavior and a semi-crystalline structure, with improved surface area and porosity due to the incorporation of graphene oxide. The adsorption experiments demonstrated high adsorption capacity and efficient adsorption kinetics for the drug CPFX. Furthermore, the prepared adsorbent showed good retrievability and reusability.

Summary: The successful synthesis of NaX nanocrystals using an organic, additive-free hydrothermal approach was reported in this paper. The NaX nanocrystals were found to act as an effective nucleating agent in the crystallization of PVA, enhancing the crystallinity degree of the nanocomposite. The effective energy barrier for the PVA/NaX nanocrystals system was shown to be smaller than that of neat PVA using the Friedman isoconversional method.

Summary: The study focuses on the efficient electrosorption of U(VI) from uranium-containing wastewater using polyvinyl alcohol/graphene oxide composite electrodes, with PVA/GO-4 showing the best performance. The Langmuir model and first-order model are suitable for predicting the adsorption behavior, with U(VI) reaching a capacity of 333.0 mg/g at 0.9 V. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) confirm the electrosorption mechanism.

Summary: Phytic acid-assisted PANi/PVA hydrogel with self-reinforcing features is developed, showing enhanced mechanical performance. Phytic acid plays a crucial role in salinizing aniline and forming hydrogen bonds with PVA, resulting in conductive PANi and structure orientation. The hydrogel exhibits improved fracture strength, Young’s modulus, and toughness after repetitive stretching, attributed to the anisotropic structures fixed by hydrogen bonds. The PVA/PA/PANi hydrogel shows good mechanical durability and reusability, making it a reliable strain sensor.

Summary: The presence of uranium in wastewater poses toxic and hazardous risks to the environment and human health, presenting a major challenge for achieving sustainability. In this study, a hydrothermal and freeze-drying process was used to create an aerogel material capable of selectively and effectively removing uranium from wastewater. The material exhibited high removal efficiency and adsorption capacity for hexavalent uranium. Characterization techniques were employed to analyze the composition, morphology, and formation of the aerogel. Thermodynamic analysis revealed an endothermic and spontaneous adsorption mechanism.
