“…Referring to the previous work reported by our groups, [ 31 ] the 30‐membered sulfone‐containing cyclosiloxane (SCS) was synthesized. As shown in Scheme , the vinyl‐containing poly(sulfone siloxane)s (PSVS) were prepared by the ring‐opening copolymerization of SCS and D4 Vi , using the KOH as the catalyst.…”

The enhancement in dielectric properties and self‐healing ability for dielectric materials has been a challenging subject these years. Herein, a series of self‐healed dielectric elastomers by combining the ferric ions and carboxyl‐containing poly(sulfone siloxane)s is reported. Experimental results indicate the excellent dielectric properties of obtained elastomers, as the dielectric constant up to 12.8. SEM micrographs exhibit that carboxyl groups and ferric ions can aggregate together to generate clusters, which further result in interfacial polarization. Besides, high polarity dipole units including sulfonyl units and carboxyl groups contribute to dipole polarization. The overlay of the two mentioned polarization eventually results in the high dielectric property. The dielectric constant obviously increases with the contents of carboxyl groups and ferric ions. Moreover, the samples are feasible for recycling and reprocessing with high self‐healing efficiency, owing to the reversibility of the coordination bond. A self‐healing efficiency of 92.1% in tensile strength of the obtained samples can be reached after 2 h treatment at 60 °C. And the elastomers can also conveniently recover most mechanical properties after solution treatment. This work may offer a promising method for preparing dielectric elastomers with high dielectric properties and self‐healing ability.

“…One can notice the significant contribution of the group of Feng that published a series of papers on the synthesis of different types of polymers with sulfone-and siloxane-based backbones (see e.g. [23,24]). These are prepared by thiol-ene addition, followed by oxone-based oxidation, then depolymerization into hybrid cycles and finally anionic polymerization.…”

This paper summarizes some works exploiting the ate-type addition of electron-withdrawing monomers to hydrogenosiloxane groups so as to generate new silicone materials. Two types of monomers were oligomerized onto silicone backbones, namely unsaturated phosphonate and sulfone monomers. Phosphonated silicones are thermally more resistant than conventional silicones and can be transformed into amphiphilic polymers after selective ester hydrolysis. Sulfoned silicones generate solid supramolecular elastomers thanks to the strong pseudo-ionic interactions in play between sulfone groups. Rheology and modulated DSC show a solid/viscoelastic transition around 175°C, which allows using these thermoplastic materials on a larger scale than conventional silicone urea copolymers. These results open new avenues in the generation of silicone block- and grafted-copolymers with unique functionality and properties.
