“On Water” Surface‐initiated Polymerization of Hydrophobic Monomers

Abstract

We present the "on water" surface-initiated Cumediated controlled radical polymerization ("on water" SI-CuCRP) that converts hydrophobic monomers in aqueous reaction medium to polymer brushes at unparalleled speed and efficiency.The method allows the facile conversion of avariety of common monomers under most simple reaction conditions and with minimal monomer amounts to thicka nd homogeneous polymer brushes.The highly living character of the "on water" SI-CuCRP allowed the preparation of decablock (homo)polymer brushes and opens the pathway to sequentially controlled polymer brushes on solids.

Translating Surface-Initiated Atom Transfer Radical Polymerization into Technology: The Mechanism of Cu0-Mediated SI-ATRP under Environmental Conditions

“…13 An alternative, highly efficient approach to circumventing the need for deoxygenation relies on the use of zerovalent copper, Cu 0 , which acts as a source of active catalyst, 14,15 simultaneously consuming dissolved oxygen when the polymerization mixture is not directly exposed to air. 16,17 Although the robustness of Cu 0 -mediated SI-ATRP for the synthesis of multifunctional, gradient and microstructured polymer brushes has been already proven through the seminal works of Jordan et al [18][19][20] and also by several authors of the present work, 21,22 little has been revealed about the mechanism of this grafting process, and its tolerance to oxygen.…”

Surface-Initiated Cu(0)-Mediated CRP for the Rapid and Controlled Synthesis of Quasi-3D Structured Polymer Brushes

“…13 Compared to the other SI-CRP methods, including those that make use of homogeneous catalytic systems, 20−23 as well as Cu(0) powder and wires, the simple and straightforward setup of SI-Cu(0) plate -CRP is advantageous. 11,15 A simple variation of the distance between the copper plate and the initiating substrate by tilting one or both the surfaces, or the use of a patterned Cu(0) plate, enable the preparation of defined brush gradients and structured polymer films. 11−13 Similarly easy is the fabrication of arrays of different polymer brushes on one substrate with the use of an intermediate mask.…”

Highly Enhanced Adsorption For The Removal of Hg (II) From Aqueous Solution By Co-Polymerized Al2O3 Nanocomposites Fabricated By Improved Sol-Gel Combustion Route: Synthesis, Adsorption Kinetics & Isotherm Modelling

“…Finally, the precipitate was filtered using a Buchner funnel and washed several timed with distilled water and ethanol to remove monomers, oligomers and excess oxidant until the filtrate become almost colorless. At 80° C the precipitate was dried for 24h [63][64][65][66].…”

“…Al 2 O 3 nanoparticles were coated with different loadings of poly (aniline coanthranilic acid "PANAA") copolymer by using surface-initiated polymerization (SIP) method [63][64][65][66]. 8 ml conc.…”

“…In this work, we focus on the synthesis of poly(aniline co-anthranilic acid)/Al 2 O 3 nanocomposite (PANAA/ Al 2 O 3 ) using the surface initiated polymerization (SIP) method [63][64][65][66]. Various experimental factors influencing the adsorption process along with the isotherm models, kinetics, and thermodynamic investigation have been examined.…”
