“…For example, fluorination in an inert atmosphere leads to hydrophobization of polyethylene [98] due to the occurrence of fluorine-containing groups (Figure 3). While the presence of oxygen in the reaction mixture in parallel with the substitution of hydrogen to fluorine leads to the formation of polar groups on the surface -CHF(C=O)SNF-and - [41] having a high affinity to water. The set of the detected functional groups for the fluorination of polyethylene in the presence of oxygen is presented in Figure 3.…”

“…An informative and express method for monitoring the surface condition as a result of chemical modification is the wetting method, i.e., measuring contact angles of liquids in contact with a solid under various conditions [41,[67][68][69]. This technique has been found in more than half of publications devoted to the direct fluorination of polymers.…”

“…Knowledge of γ d SV and γ p SV change allows one to directly regulate the adhesion of components in processes of composite materials preparation [92], and coatings application and susceptibility to dyes [23,41]. Despite this, many researchers limit analysis of these θ a(H2O) experimental data to the qualitative evaluation of the degree of fluorination.…”

“…It reduces the concentration of defects at the interface [38,39], which leads to improved mechanical properties. Optimization of the wetting ability of polymer surfaces by fluorination is promising for use in offset printing [30,40,41], ensuring the protective properties of polymer materials [29,[42][43][44][45][46], membrane [27,47]; and sorbents [38] performance. Direct fluorination of polymers also results in the formation of deep and shallow charge traps on a surface that improves dielectric [48][49][50][51], piezoelectric [52,53] properties, surface conductivity [54,55], breakdown [48,56], and DC flashover [57][58][59][60][61][62] voltages.…”

Direct fluorination of polymers is a widely utilized technique for chemical modification. Such introduction of fluorine into the chemical structure of polymeric materials leads to laminates with highly fluorinated surface layer. The physicochemical properties of this layer are similar to those of perfluorinated polymers that differ by a unique combination of chemical resistance, weak adhesion, low cohesion, and permittivity, often barrier properties, etc. Surface modification by elemental fluorine allows one to avoid laborious synthesis of perfluoropolymers and impart such properties to industrial polymeric materials. The current review is devoted to a detailed consideration of wetting by water, energy characteristics of surfaces, adhesion, mechanical and electrical properties of the polymers, and composites after the direct fluorination.

“…The dynamics of the morphological spectrum expressed in dimensionless units of the radius of the localization region and the derivative of the model (1) are anticorrelated at the level of 0.78±0.08. Since it is known [22] that the PET surface hydrophilicity increases sharply during gas-phase treatment with mixtures whose active reagents are fluorine and oxygen, when latex hits the effective surface of a nonwoven fabric, the processes of diffusion of latex as a colloidal solution into the thickness of the nonwoven material and intensive water sorption by the PET fibers surface, hydrophilized by oxyfluorination begin to compete. This phenomenon increases the uncertainty in predicting the sorption capacity at close to critical values of the rubber concentration in latex.…”

An approach to structural and functional modelling of the oxyfluorinated nonwovens based composite materials has been developed. The structural component of the model is presented in the form of integral and differential characteristic functions of the planar heterogeneity. The correlation analysis methods revealed the existence of links between the latex sorption capacities and the nanostructural characteristics of the experimental samples' SEM-images. The obtained functional-structural model allows us to quantify the expected values of sorption capacities of the nonwoven fiber materials under the certain restrictions on the chemical compositions of the impregnating mixtures.

This study investigated novel methods for treating the surface of nitrile‐butadiene rubber to enhance its stability and resistance to thermal oxidation and aggressive media. The rubber surface was modified using 1,1,2‐trifluoro‐1,2,2‐trichlorethane. The study found that the duration of the modification strongly affected specific properties of the rubbers examined. It was observed that surface modification with 1,1,2‐trifluoro‐1,2,2‐trichlorethane improved the properties of nitrile‐butadiene rubber. Subsequently, the impact of the modification duration on morphology, thermal resistance, and chemical resistance was presented.
