Fluoropolymers with very low surface energy characteristics

Low surface energy surfaces from self-assembly of perfluoropolymer with sticky functional groups

“…Therefore, considerable research efforts have been directed toward the development of alternative, low surface energy polymeric materials with good film-forming characteristics. Many fluorinated polymers, such as fluorinated polyacrylates, polymethacrylates, and polysiloxanes [7][8][9][10][11][12][13][14], have been synthesized, and most of the polymer films fabricated by spin-coating solutions of these polymers on the solid surfaces exhibited ultralow surface energies (less than 12 mJ m À2 ). However, despite their ultralow surface energy and good film quality, these films have weak adhesion to surfaces, which thereby causes poor stability and consequently limits their applications.…”

Surface segregation of fluorinated moieties on poly(methyl methacrylate-ran-2-perfluorooctylethyl methacrylate) films during film formation: Entropic or enthalpic influences

“…As we know, the perfluoroalkyl moieties have a great influence on its surface tension [31,32]. In fluoroalkyl acrylate homopolymers (comb-like), the tight packing of the long perfluoroalkyl side chain can result in dense CF 3 terminal groups at the surface and the low surface tension [31].…”

“…In fluoroalkyl acrylate homopolymers (comb-like), the tight packing of the long perfluoroalkyl side chain can result in dense CF 3 terminal groups at the surface and the low surface tension [31]. In addition, a conformational change of the polymer chains in solution could be caused by selecting certain solvents [33].…”

Synthesis and property investigation of three core‐shell fluoroacrylate copolymer latexes

“…It has been reported that the surface properties of fluoroacrylate copolymers were related to the organization of fluorinated side chain, which was governed by the chain length, the chemical structure, and the flexibility of main chain. [23][24][25][26] Therefore, studying the influence of fluorinated side chain structure on the properties of core-shell fluoroacrylate copolymer latex and comparing the properties of core-shell fluoroacrylate latex with general fluoroacrylate copolymer latex will be helpful to select suitable fluorinated acrylate monomer, design polymer microsphere, and reduce cost.…”
