“…The formation of core–shell structure was similar to that of the conventional emulsion polymerization. However, after the formation of styrene‐sodium sulfonate (St‐NaSS) emulsion during the polymerization process, on the one hand, from the dynamic point of view, the main chain contains sodium sulfonate polar groups, developing and enhancing the secondary bond forces between the polar groups and water molecules, on the other hand, from the thermodynamics point of view, the interfacial tension between P(St‐NaSS) phase and aqueous phase was weak . In the later stage of emulsion polymerization, P(St‐NaSS) phase contains polar groups to molecular surface diffusion formed the shell phase, modified acrylic ester (BC 2 NP 2 ) phase and the other part of styrene stay in molecular internal contraction formed nuclear phase.…”

“…In addition, the replacement of hydrogen atoms by fluorine atoms not only forms a strong C F bond, but also strengthens the side C C chain, which brings the fluorinated polysiloxanes with unique properties including good mechanical behavior, excellent thermal stability, low-refractive index, predominant hydrophobicity, and oleophobicity. [12][13][14] Therefore, the fluorinated polysiloxanes are widely used in textile and leather product finishing, floor sanding, paint and coating additives, defoamers and hydraulic oils in the aviation industry. [15][16][17][18][19] It has been confirmed that the length and crystallinity of fluorocarbon side-chains, the type of spacer group between the main chain and fluorocarbon side-chains affect the surface properties of fluorinated materials.…”

“…Since fluorine atoms with strong electronegativity are strongly bonded to the carbon atoms, the chemically stable fluoroalkyl side groups limit others atoms to traverse and wedge into the SiOSi main chain, playing a “shielding effect.” 11 Therefore, the fluorinated polysiloxanes exhibit excellent chemical resistance. In addition, the replacement of hydrogen atoms by fluorine atoms not only forms a strong CF bond, but also strengthens the side CC chain, which brings the fluorinated polysiloxanes with unique properties including good mechanical behavior, excellent thermal stability, low‐refractive index, predominant hydrophobicity, and oleophobicity 12–14 . Therefore, the fluorinated polysiloxanes are widely used in textile and leather product finishing, floor sanding, paint and coating additives, defoamers and hydraulic oils in the aviation industry 15–19 …”

“…However, in the process of emulsion film formation, small molecule emulsifiers easily desorb from polymer particles and migrate to the surface of the coating, a weak boundary layer is produced at the bonding site, resulting in shrinkage of the film, affecting the water resistance and adhesion of the coating. Moreover, commonly used emulsifiers contain sulfonic acid groups, which remain in the film and are corrosive to the metal substrate, the dosage of emulsifier should be reduced as much as possible .
