Poly(fluoroacrylate)s with tunable surface hydrophobicity via radical copolymerization of 2,2,2-trifluoroethyl α-fluoroacrylate and 2-(trifluoromethyl)acrylic acid

Abstract

Fluorinated polyacrylates with tunable surface hydrophobicity are prepared via radical copolymerization of an α-fluoroacrylate and 2-(trifluoromethyl)acrylic acid.

Altering the bio-inert properties of surfaces by fluorinated copolymers of mPEGMA

“…13 r FATRIFE = 1.65 ± 0.07 and r MAF = 0 at 56 °C According to these studies, the resulting copolymers based on α-fluoroacrylates were statistic. 48 After reaction, these copolymers were purified by precipitation from pentane and dried. In addition, and compared to such copolymers, owing to its hydration structure, 3 PMEA was also prepared as a reference polymer for this present study.…”

“…Here, following investigations dealing with small amounts of fluorinated monomers in copolymers with hydrophilic polymers, 2,39,40 we designed and synthesized new fluorinated copolymers based on the alpha-fluoroacrylate monomer, 1,1,1,3,3,3-hexafluoropropan-2-yl 2fluoroacrylate (FAHFiP). 48 FAHFiP can be radically polymerized and has a high fluorine content; therefore, a small amount of FAHFiP in copolymers with mPEGMA is expected to make the copolymers insoluble in water. An optimal composition for the development of bioinert properties has been reported for fluorinated moieties and PEG block polymers.…”

Protective coatings for ceramic artefacts exposed to UV ageing

“…As regards poly(meth)acrylates bearing semifluorinated side chains, the appearance of highly ordered surfaces with CF3 groups disposed on the top layer due to an internal microphase separation was observed 9 . Poly(fluoromethacrylate)s present unique characteristics including reduced friction coefficients, low surface energies, nonadhesive nature, water and oil repellency and solid state assembly into smectic layers, making them suitable as chemical resistant antifouling coatings 10 .…”

Access to Fluorinated Polymer Surfaces with Outstanding Mechanical Property, High Optical Transparency, and Low Surface Energy via Nonafluoro-tert-Butyl Group Introduction

“…According to the synthetic approach, the fluorination of common polymers can be divided into (i) copolymerization with fluorinated monomers, 10,11 (ii) direct functionalization using fluorination agents such as F 2 and HF, 12−16 and (iii) introduction of fluorinated functional moieties. 17,18 Copolymerization is a very general method of introducing fluorofunctionalities into polymers owing to its ease of implementation and cost-effectiveness; 19,20 however, the scope of fluorinated monomers is restricted by the need to carefully consider the polymerization conditions and the level of synthetic difficulty.…”

In contrast, the introduction of fluorinated moieties offers the advantages of mild reaction conditions, applicability to a wide range of polymers, and control over functionality (or selective functionalization) in the case when the polymer has certain reaction sites. ,,, However, this technique still suffers from drawbacks due to the complex synthesis of fluorination agents and the limited scope of fluorinated moieties …”
