Article Synopsis
  • This study explores the creation of a superspreading polymer membrane (SPPM) using self-assembly techniques with polyvinyl alcohol (PVA) and PP melt-blown nonwovens to address challenges in large-scale application.
  • The resulting amphiphilic SPPM is cost-effective, energy-efficient, and thermodynamically stable, demonstrating successful PVA assembly on fiber surfaces as shown by advanced microscopy techniques.
  • Additionally, the SPPM exhibits impressive spreading performance for both water and oil, outperforming traditional materials in applications like oil-water separation, seawater desalination, and ion separation, contributing to advancements in superspreading materials.

Fog harvesting is considered a promising freshwater collection strategy for overcoming water scarcity, because of its environmental friendliness and strong sustainability. Typically, fogging occurs briefly at night and in the early morning in most arid and semiarid regions. However, studies on water collection from short-term fog are scarce.

The integral catalytic impeller can simultaneously improve reaction efficiency and avoid the problem of catalyst separation, which has great potential in applying heterogeneous catalysis. This paper introduced a strategy of combining electroless copper plating with 3D printing technology to construct a pluggable copper-based integral catalytic agitating impeller (Cu-ICAI) and applied it to the catalytic reduction of 4-nitrophenol (4-NP). The obtained Cu-ICAI exhibits very excellent catalytic activity.

The unmodified clay has been fully exfoliated in epoxy resin with the aid of a novel ultrafine full-vulcanized powdered rubber. Epoxy/rubber/clay nanocomposites with exfoliated morphology have been successfully prepared. The microstructures of the nanocomposites were characterized by means of X-ray diffraction and transmission electron microscopy.
