Novel, one-step synthesis of zwitterionic polymer nanoparticles via distillation-precipitation polymerization and its application for dye removal membrane

Abstract

In this work, poly(MBAAm-co-SBMA) zwitterionic polymer nanoparticles were synthesized in one-step via distillation-precipitation polymerization (DPP) and were characterized. [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (SBMA) as monomer and N, N′-methylene bis(acrylamide) (MBAAm) as cross-linker are used for the synthesis of nanoparticles. As far as our knowledge, this is the first such report on the synthesis of poly(MBAAm-co-SBMA) nanoparticles via DPP. The newly synthesized nanoparticles were further employed for the surface modification of polysulfone (PSF) hollow fiber membranes for dye removal. The modified hollow fiber membrane exhibited the improved permeability (56 L/ m2 h bar) and dye removal (>98% of Reactive Black 5 and >80.7% of Reactive orange 16) with the high permeation of salts. Therefore, the as-prepared membrane can have potential application in textile and industrial wastewater treatment.

Functional Zwitterionic Polymers on Surface: Structures and Applications

“…Ibrahim et al designed a copolymer of N, N'-methylene bis(acrylamide) (MBAAm) and PSBMA, poly(MBAAm-co-SBMA), which can form stable nanoparticles in aqueous solution. [60] The nanoparticles were used to modified polysulfone hollow fiber membranes for dye removal after preparing by dry/wet phase inversion method. The membrane showed high water permeability and dye removal ability.…”

Removal of metal ions and humic acids through polyetherimide membrane with grafted bentonite clay

“…In comparison with the typical polymerization methods like group transfer polymerization, radical-polymerization and chain transfer polymerization, distillation-precipitation polymerization offers greater benefits such as, atom economy, lesser reaction time, no metal catalyst, and easy isolation. The mechanism of distillation-precipitation polymerization follows the order of radical initiation of monomer or cross-linker and subsequent chain propagation by chain addition, which increases colloidal stability of modified nanoparticles due to high surface charge 17 , 18 .…”

Enhancing Performances of Polydopamine as Cathode for Lithium‐ and Potassium‐Ion Batteries by Simple Grafting of Sulfonate Groups

“…The increase of negative ζ‐potential of the nanoparticles could be attributed to the grafting of sulfonate group. Consequently, the modified PDA exhibits more pronounced negative ζ‐potential and develop an electrical double layer, which avoids the formation of aggregates [28] . The incorporation of sulfonate groups into PDA was mainly based on the Michael addition [29] (Scheme 1).…”
