Summary: Polymeric membrane-based pervaporation separation for desalination and dehydration has been studied using surface-functionalized carbon nanotubes (CNTs) in poly(vinyl alcohol) (PVA) membranes. The hydrophilicity of the functionalization agents is critical for the construction of water-conduction pathways. Small amounts of functionalized CNTs significantly enhance the permeation fluxes of the membranes. PVA-CNT shows the highest performance for desalination, while ozonized lignin-functionalized CNTs are most effective for dehydration.

Summary: Inverse vulcanization uses an organic compound as a reagent to crosslink elemental sulfur, resulting in a polymeric material with a high sulfur content. This study demonstrates the first attempt on extending the scope of crosslinking agents to saturated compounds in inverse vulcanization, using 1,3,5-triisopropylbenzene (TIPB) as the reagent. The reactions between TIPB and elemental sulfur involve ring-opening reaction of S-8, leading to sulfur radicals at sulfur chain ends, which then transfer to the isopropyl groups of TIPB, and undergo radical coupling reactions with carbon radicals and sulfur radicals.
