“…1 shows the XPS spectra of the resulting films. The strong signals of F located at 689.5 eV and C located at 291.5 eV in the XPS spectra, which were assigned to F and C of ACF 2 and ACF 3 groups, respectively [11,12,26], indicated the formation of self-assembly films on the surface. The advancing CA and surface energy data in Table 1 also showed the evidence of formation of low surface energy films on the Ti plate surface in solutions of DOPA-PFOMA with various concentrations.…”

“…In Table 1, the average and surface F/C atomic ratios are presented together with the FSE calculations and the CA measurements, for the different fluorinated polymers synthesized. The FSE follows a known tendency [24][25][26][27] with the average fluorine concentration, i.e. the lower the average fluorine content, the higher the FSE.…”

“…The CA of the neat matrix was increased when fluorine was incorporated following any of the studied modifications. When the chemical composition of a surface is responsible of the hydrophobicity, a linear relationship is found between the CA and the measured F/C surf ratio [27,29,30]. When the plot of CA versus F/C surf is not linear, not only the composition, but other effects play a rol in the surface hydrophobicity.…”

Recently developed low fluorine containing polymers are advanced materials which confer advantageous properties to surfaces at a lower cost than conventional fluoropolymers (like PTFE), and are also more easily processable. Fluoropolymer surfaces are characterized by a low surface energy, high oleo and hydrophobicity, low coefficients of friction, among many other properties. This makes them desired materials in microelectronics, antifogging, antifouling and medical applications, to name a few. Fluorinated compounds are not easily coupled with macromolecules or common organic systems, and great efforts are made to compatibilize fluorinated species with hydrocarbon polymers. In this work, two chemical routes were explored in order to incorporate perfluorinated alkyl chains in an epoxy-amine based thermoset. On one side, a perfluoroalkyl thiolated molecule was used as a stabilizing ligand for silver nanoparticles, which were incorporated in the matrix polymer. On the other hand, fluorinated chains containing epoxy functionalities, were used as the matrix modifier. In the first case, fluorinated chains covering the nanoparticles, were mixed with the matrix, while in the second case, the fluoroalkyl chains were chemically linked to the network. Fluorine migration to the air—polymer interface was confirmed by X-Ray photoelectron spectroscopy (XPS). The materials hydrophobicity was then studied in terms of their contact angle with water (CA), as a function of the surface composition and the topography. Scanning electron microscopy (SEM) and atomic force microscopy (AFM), operated in moderate and light tapping modes, were used to morphologically describe the surfaces. An exhaustive surface analysis was made in order to explain the different hydrophobicity grades found.

“…Li et al [6] successfully synthesized a series of semi-fluorinated fluorocarbon diblock copolymer of poly(butyl methacrylic-co-perfluoroalkyl acrylic) with the contact angle of water larger than 100 3 . Grampel et al [7] investigated the surface of the copolymer of 1,1-dihydroperfluoroheptyl methacrylate and methyl methacrylate. Although fluorine-containing polymers are effective as surface modification agents, fluorine-containing monomers are still relatively expensive for application in daily life and are not readily commercially available.…”

Methyl methacrylate and butyl acrylate were copolymerized in the presence of C = C containing silane coupling agent and further grafted with hydroxyl silicone oil (HSO) in butyl acetate. The conversion and grafting degree of HSO were determined by a weighing method. The structure and the surface properties of silicone-grafted acrylic copolymer coatings were characterized by Fourier transform infrared spectroscopy (FTIR), CP/MAS, 13C-NMR, optical contact angle (OCA), and X-ray photoelectron spectrometer (XPS). It was found that a relatively high grafting degree of HSO onto acrylic copolymer can be obtained by using acetic acid as the catalyst and methacryloxypropyltrimethoxysilane (MAPMS) as the silane coupling agent. The HSO graft can effect a decrease in the surface free energy of polymer films and improve the hydrophobic property of acrylic copolymer coating.
