Circulating-infiltrating preparation of hydrophilic nylon 6 membrane to hydrophobic MWCNT@nylon composite membrane

Mai Thanh Phong,

et al.

Abstract: The ion adsorption capacity has been added to the nylon 6 microfiltration (MF) membrane by grafting the fibers in its structure with carboxylated multi-walled carbon nanotubes (MWCNT-COOH). Through a direct three-step functionalization reaction with hexamethylenediamine (HMDA) and MWCNT-COOH, the multi-walled carbon nanotubes grafted nylon (MWCNT@nylon) fibers are made up of original nylon 6 and intermediate amino-enriched (nylon-NH2) membranes. Chemical structure analysis shows that HMDA and MWCNTs were graft… Show more

“…Multi-wall carbon nanotubes (MWCNTs) are a well-known type of carbon nanomaterial that is widely used in infrastructure, plastic tools, biomedical products, analysis, and electrical chemistry [20]. Furthermore, carbon-based nanostructures were utilized in the process of adsorption applications [21,22], the removal of metal from wastewater [23], and the recycling of agricultural waste [24]. MWCNTs interact covalently with hydroxyl groups due to their cylindrical shape, which imparts mechanical and thermochemical functions [25,26].…”
