“…[23][24][25][26] Despite their widespread use, only a limited number of studies have investigated the controlled surface polymerization from organophosphonic acid initiators and these exclusively focused on metal surfaces. [27][28][29][30][31] We therefore report the controlled ATRP of polyelectrolytes using an organophosphonic acid initiator covalently attached to silica and mica substrates. Polyacrylic acid and poly(sulfopropyl methacrylic acid) brushes were examined owing to their known responsiveness to pH and ionic strength.…”

The present work investigates the electrografting of in situ generated 2-bromoisobutyrate p-nitrophenyldiazonium salt (PD-Br) after the electroreduction of its nitro precursor (A-NO 2 Br) into amine on NiTi followed by the surface initiated atom transfer radical polymerization (SI-ATRP) of 2-hydroxyethyl methacrylate (HEMA). Nitinol is interesting for many biomedical applications. A great deal of attention has thus been paid to its surface modification in order to impart and/or improve its surface properties. This can be achieved using SI-ATRP which requires initiator i.e. PD-Br in this work. Results show the effective electrografting of PD-Br and the preservation of the TiO 2 surface layer (responsible for the biocompatibility of Nitinol) made possible by the gentle conditions used for the in situ generation. Nitinol corrosion resistance has been shown to be improved. This SI-ATRP initiator (PD-Br) leads to the successful polymerization of HEMA grafted at the surface of NiTi. Furthermore, the ATRP polymerization of HEMA has a double effect on the corrosion resistance of the modified NiTi. First, the conditions used contribute to a hydrothermal-like treatment which reinforces the TiO 2 layer of NiTi and so its biocompatibility but also its corrosion resistance. Second, the layer of PHEMA grafted further improves the corrosion resistance.

“…Concerning synthesis methods, which are common for groups described herein, free radical polymerization and photopolymerization have been the most studied, but there are also reports of controlled radical polymerization: atom transfer radical polymerization (ATRP) [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ] ( Scheme 2 ) or reversible addition fragmentation transfer (RAFT) processes [ 6 , 19 , 20 , 21 , 22 , 23 , 24 ] ( Scheme 3 ). Living polymerization techniques allow one to obtain well-defined polymers with tunable structures, compositions, and properties [ 5 ].…”

Efficient separation technologies are crucial to the environment and world economy. The challenge posed to scientists is how to engineer selectivity towards a targeted substrate, especially from multicomponent solutions. Polymer-supported reagents have gained a lot of attention in this context, as they eliminate a lot of inconveniences concerning widely used solvent extraction techniques. Nevertheless, the choice of an appropriate ligand for immobilization may be derived from the behavior of soluble compounds under solvent extraction conditions. Organophosphorus compounds play a significant role in separation science and technology. The features they possess, such as variable oxidation states, multivalence, asymmetry and metal-binding properties, highlight their status as a unique and versatile class of compounds, capable of selective separations proceeding through different mechanisms. This review provides a detailed survey of polymers containing phosphoric, phosphonic and phosphinic acid functionalities in the side chain and covers main advances in the preparation and application of these materials in separation science, including the most relevant synthesis routes (Arbuzov, Perkow, Mannich, Kabachnik-Fields reactions, etc.), as well as the main stages in the development of organophosphorus resins and the most important achievements in the field.
