Reversible addition–fragmentation chain transfer (RAFT) copolymerization of fluoroalkyl polyhedral oligomeric silsesquioxane (F-POSS) macromers

Synthesis of POSS-containing fluorosilicone block copolymers via RAFT polymerization for application as non-wetting coating materials

“…At a feed percentage of the fluoroalkyl methacrylate macromer FMA-POSS to MMA in the range 0-25 wt%, they failed to acquire the homopolymer PFMAPOSS, but a well-controlled P(FMAPOSS-co-MMA) copolymer with lower polydispersity index (1.03-1.08) was obtained [18]. Additionally, they found that the non-wetting properties of the copolymer were enhanced with the increased FPOSS content according to dynamic contact angle measurements [18]. Deng and co-workers successfully synthesized well-defined hybrid PMAPOSS-b-PMMA block copolymers with different POSS block lengths using cumyl dithiobenzoate as the RAFT agent, and these POSS-based block copolymers were further applied as modifiers of epoxy thermosets [19].…”

“…By combination of the advantages of fluoropolymers and silicone, the POSS-poly(acrylic acid) (POSS-PAA) polymer was prepared by hydrolysis of POSS-poly(tert-butyl acrylate) that was synthesized via RAFT polymerization in a living manner using a POSS-containing trithiocarbonate chain transfer agent (CTA) [17]. Ramirez and co-workers synthesized fluoroalkyl methacrylate-POSS copolymer with methyl methacrylate (MMA) via RAFT polymerization [18]. At a feed percentage of the fluoroalkyl methacrylate macromer FMA-POSS to MMA in the range 0-25 wt%, they failed to acquire the homopolymer PFMAPOSS, but a well-controlled P(FMAPOSS-co-MMA) copolymer with lower polydispersity index (1.03-1.08) was obtained [18].…”

General Strategy for the Preparation of Stable Luminous Nanocomposite Inks Using Chemically Addressable CsPbX3 Peroskite Nanocrystals

“…POSS-based polymers have been widely adapted in hybrid materials to induce hydrophobicity, and good mechanical and thermal properties, [36][37][38] owing to the threedimensional cube-like silsesquioxane cage structures for the inorganic-particle effect and steric effect, and its low surface energy for hydrophobic passivation layer. 36,37,[39][40][41][42] Scheme 1. The design of PMPOPNC by copolymerization with chemically addressable NCs Herein, a new approach is developed to interface CsPbX3 NCs with polymers by copolymerizing methacrylic acid capped NC (MA-NC) with POSS-appended methacrylate monomer (MA-POSS) and/or methyl methacrylate (MMA) (Scheme 1).…”

Hyperbranched Polysiloxanes Based on Polyhedral Oligomeric Silsesquioxane Cages with Ultra-High Molecular Weight and Structural Tuneability

“…The alkene functional groups are first introduced into POSS cage molecules through organic synthesis, and then polymerization techniques such as RAFT [14][15][16][17], ATRP [18,19], ROMP [20][21][22] allow subsequent generation of POSS-cage-containing polymers either by themselves or with other alkene monomers. Other ways, such as coupling reactions, have also been utilized for a similar purpose.…”
