Owing to the rise in global population and living standards, waste treatment has inevitably become a critical issue for sustainable environment. In particular, an effective recycling process, it is vital disassemble different types of materials by removing adhesives used packaging. However, this removal process requires harsh solvents (acidic organic) that are unfriendly nature may cause additional pollution. To address issue, functional adhesive can be removed without use have drawn...
Common polymer binders are insulators, which significantly diminish the battery performance owing to their low electron mobility. For aqueous sodium-air batteries (SABs) exhibit reliable as energy storage systems,...
Macroporous polymers have gained significant attention due to their unique mass transport and size-selective properties. In this study, we focused on Polyimide (PI), a high-performance polymer, as an ideal candidate for macroporous structures. Despite various attempts create PI (Macro PI) using emulsion templates, challenges remained, including limited chemical diversity poor control over pore size porosity. To address these issues, systematically investigated the role of poly(amic acid)...

Abstract Graphene encapsulation is an attractive surface‐coating technology that can simultaneously improve the rate capability and cycle stability of nickel‐rich LiNi x Co y Mn 1− − O 2 (NCM). Here, carbon with addition polyethylenimine (PEI) polyhedral oligomeric silsesquioxane (POSS), which effectively suppress access to generation harmful factors in electrolyte maximize performance NCM, described. The PEI‐POSS/carbon layer not only facilitates electron lithium‐ion transport on NCM...
The rapid development of foldable and rollable displays electronic devices has aggravated the need for flexible miniaturized energy-storage devices, such as micro-supercapacitors (MSCs). Existing have several shortcomings, high cost materials, energy consumption, complicated fabrication methods. This study introduces a straightforward method fabricating MSCs based on reduced graphene oxide (rGO) manganese utilizing printing technique intense pulsed white light (IPWL) technology. Using this...
