“…This is because the network cross-linking structure limits the evaporation of small water molecules from the film to the air. It is important to point out that in the sample of FSi-PAcr/PB, the lowest water vapor amount is 175.3 g/(m 2 ·24 h), for which it is assumed that the non-cross-linked free FSi chain segments migrate both to the film–air and film–substrate interfaces, forming the barrier layers of water vapor . In addition, XPS spectra of the film–air interface of FSi-PAcr/PB latex film is shown in Figure S6.…”

Binder-free pigment dyeing/printing of textiles is a type of environmentally friendly and clean production technology that utilizes polymer/pigment hybrid latex. Although it has widespread use, the manner in which the nature of the hybrid latex influences the film formation and how systems can be designed to improve softness and air-permeability is still unclear. In this study, we synthesized a series of fluorosilicone-modified polyacrylate/pigment hybrid latexes to explore how cross-linking degree affects film-formation behavior and binder-free pigment printing performance on fabric, where the cross-linking structure is controlled by a silane coupling agent. Our results show that the cross-linking degree of the fluorosilicone-modified polyacrylate chain plays a vital role in chain diffusion, latex particle packing, and deformation. Further, it controls "skin" formation during the process of hybrid latex drying. The dried hybrid films not only have homogeneity and good barrier performance but also exhibit a soft state (low T g , − 28.3 °C) owing to the silicone chain segment and bound water with a plasticizing effect. Interestingly, our results show that the cross-linking degree of hybrid latex particles changes as a function of the morphology of the printed polyester (PET) fiber. Further, as a result of the improvement of the softness and airpermeability of the binder-free printed PET fabric, the surface of single yarns is uniformly wrapped by hybrid films with a high crosslinking degree. These insights allow for effective development of textile pigment printing technology controlled by the film-formation behavior of hybrid latex.

“…Over the past decades, perfluoropolyether materials have been successfully used in anti-smudge, self-cleaning, superhydrophobic, and hydrophobic coatings, and so forth. 13,[32][33][34][35] In this work, our group tried to prepare polymethylhydrosiloxane with different hydrogen contents by anionic ring-opening reactions. Then, four different equivalent PPM were introduced into polymethylhydrosiloxane to prepare four kinds of PEPS with different grafting ratios.…”

Developing materials with a combination of superior properties such as hydrophobicity and low dielectric is very challenging. This work proposes a design strategy based on the synergistic effect of silicon fluorine to fabricate fluorous silicon materials with excellent hydrophobicity and dielectric properties. Perfluoropolyethyl propionate polysiloxane (PEPS) with different grafting ratios was synthesized by the reaction of polymethylhydrosiloxane (PMHS) and perfluoropolyethyl methacrylate (PPM) hydrosilane. The self-crosslinking perfluoropolyether methyl propionate polysiloxane (PFSP) coating with good hydrophobicity and low dielectric was prepared by further introducing triethoxyvinylsilane (TOVS) into the PEPS and condensing. The fluorine content of two interfaces (film PET and film air) of PFSP-4 film was analyzed by XPS, and it was found that the fluorine content of the film air interface was 46.19% and that of the film PET interface was 17.3%. With the increase of perfluoropolyether content in PFSP, fluorine-containing groups migrate to the coating surface, which is more conducive to enhancing the hydrophobicity of the coating. The results indicate that the film has excellent hydrophobicity with a high water contact angle of up to 117 due to the introduction of PPM. In addition, the dipole moment of perfluoropolyether methyl methacrylate is 2.27, which is lower than that of methyl. Therefore, the introduction of a large number of perfluoropolyether bonds effectively reduces the polarity of the material, which is beneficial to its low dielectric properties. The dielectric constant of PFSP-4 is 2.4, which is 33% lower than that of a fluorine-free silicone coating. The results show that the self-crosslinking perfluoropolyether methacrylate polysiloxane coating has excellent hydrophobicity and low dielectric properties, so it has a feasible application prospect in the electronic industry.
