Synthesis of fluorinated phosphorus-containing copolymers and their immobilization and properties on stainless steel

Abstract

A series of fluorinated-phosphonic acid methacrylates were synthesized by free radical polymerization using heptadecafluorodecyl methacrylate (HDFDMA) and (dimethoxyphosphoryl) methyl methacrylate (DMPMM) monomers for potential application as anti-corrosion coatings.

Radiation induced graft polymerization of fluorinated monomers onto flax fabrics for the control of hydrophobic and oleophobic properties

“…After the grafting procedure onto irradiated flax fabrics, the FTIR spectrum exhibits the presence of new signals at 1735, 1200 and 1146 cm − 1 , characteristic of C--O, C-F and C-O-C groups of M8 units of the grafted polymer chains, respectively [14,43,44]. Two bands appear also at 655 and 703 cm − 1 resulting from a combination of rocking and wagging vibrations of the CF 2 groups, respectively [4,45]. These bands are also present in the P(M8) spectrum but do not appear for the pristine fabric and the non-irradiated sample treated with M8.…”

One-Step Multifunctionalization of Flax Fabrics for Simultaneous Flame-Retardant and Hydro-Oleophobic Properties Using Radiation-Induced Graft Polymerization

“…Moreover, it was also observed the presence of the characteristic bands of fluorinated polymer chains at 1200 cm −1 corresponding to the C-F bonds when the monomers were combined and also for the grafting of M8 alone [39,41,42]. Two bands of medium intensity appeared at 655 and 703 cm −1 resulting from a combination of rocking and wagging vibrations of the CF 2 groups [29,43]. These results highlight the one-step grafting of both phosphorus and fluorinated monomers onto irradiated flax fabrics.…”

“…As a matter of fact, fluoropolymers have also attracted the interest of the academic and industrial scientific communities because of their excellent properties, including high heat, UV and aging resistance, outstanding solvent and chemical stability and low surface energy [28,29]. Per-and polyfluoroalkyl substances (PFAS) with alkyl chains containing six or more carbons (C n F 2n+1 with n > 6) have a strong hydrophobic and oleophobic character [17,20,[30][31][32][33][34][35].…”

Design, Synthesis and Actual Applications of the Polymers Containing Acidic P–OH Fragments: Part 2—Sidechain Phosphorus-Containing Polyacids

“…Steel plates, coated with the copolymer, displayed satisfactory anticorrosion properties under a simulated seawater environment. An original and efficient approach to development of anticorrosive agents was proposed by Kousar and Moratti [ 157 ], via the use of methacrylate copolymers containing –(CH 2 ) 2 (CF 2 ) 7 CH3 and –CH 2 P(O)(OH) 2 substituents. These copolymers formed monolayers at the stainless-steel surface (the contact angle >128°) and were stable after being submerged in water for a week.…”
