Perfluoroalkylethyl acrylate is a synthetic fluorinated monomer with the general formula Rf-CH₂CH₂-OC(O)CH=CH₂ (Rf = perfluoroalkyl chain, typically C₄–C₁₂).
Key Points:
Function: Combines a highly oleophobic/hydrophobic perfluoroalkyl "tail" with a polymerizable acrylate "head".
Use: Added to polymers/coatings to impart extreme water, oil, and stain repellency and low friction.
Applications: Waterproof textiles, stain-resistant carpets, oil-repellent paper/food packaging, and anti-fouling coatings.
PFAS Status: Classified as a PFAS (per- and polyfluoroalkyl substance), raising significant environmental and health concerns due to persistence, bioaccumulation, and potential toxicity.
Regulation: Subject to increasing global restrictions.
In short: A key PFAS chemical for durable "non-stick" surfaces, but facing phase-outs due to environmental risks.
Perfluoroalkylethyl acrylate is a specialized fluorinated monomer used to create water- and oil-repellent surfaces. Here's a concise overview (under 100 words):
Chemical Structure: Combines a perfluoroalkyl group (Rf, typically C₄–C₁₂) with an ethyl spacer linked to an acrylate group.
General formula: Rf–CH₂CH₂–O–C(=O)–CH=CH₂ (Rf = perfluoroalkyl chain).
Function: The perfluoroalkyl tail provides extreme hydrophobicity/oleophobicity; the acrylate head enables polymerization.
Properties: Imparts low surface energy, chemical resistance, and durable repellency to coatings.
Applications:
Waterproof/Stain-resistant textiles (e.g., outdoor gear).
Oil-repelling paper/food packaging.
Anti-fouling coatings (electronics, medical devices).
Regulation: Faces scrutiny as a PFAS (per- and polyfluoroalkyl substance) due to environmental persistence and toxicity concerns.
In short: A key fluorinated acrylate for "non-stick" coatings, but part of the debated PFAS family.
