“…More significantly, the FSiRF material possesses intriguing mechanical elasticity, which can be stretched to 130% strain or compressed to about 60% strain without breaking apart and can completely restore to its original shape (Figure 1e,f). Such excellent stretching and compressing performance without any deformation are rarely observed in other polymer foams and aerogel materials (e.g., inherently brittle silica aerogels) with high porosity [37,38].…”

“…PDFS-Vi-X (Vinyl-terminated poly(dimethyl-co-methyltrifluoropropyl)siloxane) with varying fluorine content (where X represents the methyltrifluoropropylsiloxane unit ratio) is synthesized via anionic ring-opening copolymerization (AROP) of cyclic oligomers [37]. The specific synthesis steps are as follows: a certain amount of D 4 , MM Vi , and TMAH were added into a three-neck flask with a stir paddle and condenser under nitrogen atmosphere.…”

Polydimethylsiloxane (PDMS) foam materials with lightweight, excellent oil resistance and mechanical flexibility are highly needed for various practical applications in aerospace, transportation, and oil/water separation. However, traditional PDMS foam materials usually present poor chemical resistance and easily swell in various solvents, which greatly limits their potential application. Herein, novel fluorosilicone rubber foam (FSiRF) materials with different contents of trifluoropropyl lateral groups were designed and fabricated by a green (no solvents used) and rapid (<10 min foaming process) foaming/crosslinking approach at ambient temperature. Typically, vinyl-terminated poly(dimethyl-co-methyltrifluoropropyl) siloxanes with different fluorine contents of 0–50 mol% were obtained through ring-opening polymerization to effectively adjust the chemical resistance of the FSiRFs. Notably, the optimized FSiRF samples exhibit lightweight (~0.25 g/cm−3), excellent hydrophobicity/oleophilicity (WCA > 120°), reliable mechanical flexibility (complete recovery ability after stretching of 130% strain or compressing of >60%), and improved chemical resistance and structural stability in various solvents, making them promising candidates for efficient and continuous oil–water separation. This work provides an innovative concept to design and prepare advanced fluorosilicone rubber foam materials with excellent chemical resistance for potential oil–water separation application.

“…It could be used to facilitate synthesis in an aqueous environment which still is advantageous for molecularly imprinted organic polymers. On the other hand, the presence of trifluoromethyl groups increases hydrophobicity, providing the water-resistant characteristic of the resulting material [ 91 ]. The surface properties of molecularly imprinted siloxanes are very important because of solvent transfer and sorption kinetics.…”

Molecular imprinting technology is a well-known strategy to synthesize materials with a predetermined specificity. For fifty years, the “classical” approach assumed the creation of “memory sites” in the organic polymer matrix by a template molecule that interacts with the functional monomer prior to the polymerization and template removal. However, the phenomenon of a material’s “memory” provided by the “footprint” of the chemical entity was first observed on silica-based materials nearly a century ago. Through the years, molecular imprinting technology has attracted the attention of many scientists. Different forms of molecularly imprinted materials, even on the nanoscale, were elaborated, predominantly using organic polymers to induce the “memory”. This field has expanded quickly in recent years, providing versatile tools for the separation or detection of numerous chemical compounds or even macromolecules. In this review, we would like to emphasize the role of the molecular imprinting process in the formation of highly specific siloxane-based nanomaterials. The distinct chemistry of siloxanes provides an opportunity for the facile functionalization of the surfaces of nanomaterials, enabling us to introduce additional properties and providing a way for vast applications such as detectors or separators. It also allows for catalyzing chemical reactions providing microreactors to facilitate organic synthesis. Finally, it determines the properties of siloxanes such as biocompatibility, which opens the way to applications in drug delivery and nanomedicine. Thus, a brief outlook on the chemistry of siloxanes prior to the discussion of the current state of the art of siloxane-based imprinted nanomaterials will be provided. Those aspects will be presented in the context of practical applications in various areas of chemistry and medicine. Finally, a brief outlook of future perspectives for the field will be pointed out.

“…The influence of impurities within the reaction system, especially moisture and residual bases, should not be ignored. The presence of water can stop the anionic polymerization process [ 39 ], so special attention should be paid to removing water throughout the reaction. In addition, the residual base in the reaction system needs to be neutralized in order to obtain PTFPMS with a stable molecular weight and performance [ 40 ].…”
