Cage and linear structured polysiloxane/epoxy hybrids for coatings: Surface property and film permeability

“…1e) and subsequently leads to a lower crosslinking density resulting in lower T g (260°C). On the other hand, pure PGMA polymer with much lower T g (about 76°C) [8] than the obtained hybrids in this study has proved that the POSS or PDMS inorganic ingredient has distinct advantage to improve the thermal stability of polysiloxane/epoxy hybrids. However, the thermo-mechanical properties of POSS-containing hybrids (Sample 1 and Sample 2) are also in good correlation with morphology features, as reported by N.M. Florea [41] in the novel nanocomposites DGEBA/DG-PDMS/POSS obtained based on diglycidylether of bisphenol A (DGEBA) combined with diglycidylether-terminated polydimethylsiloxane (DG-PDMS), reinforced with epoxy POSS nanocages.…”

“…The cage-structured POSS is normally considered to be a kind of monodisperse silica (1-2 nm) with cube inorganic core of (SiO 1.5 ) n (n = 8, 10 or 12) and the organic shell attached organic groups to give potential synthesis by covalent bonding [6][7][8][9][10][11]. When the substituent of POSS is polymerizable or reactive group, it can be incorporated into a suitable polymer backbone by (co)polymerization or functionalization reactions (e.g., grafting, initiation, and termination), thus providing an opportunity to design and build materials that have a well-defined composition and dimension to show nanophase behavior (nanocomposites) [12].…”

POSS-based glycidyl methacrylate copolymer for transparent and permeable coatings

“…In the cubic POSS, Si atoms occupy the corners of a cube and oxygen atoms located at the edges of core (2,3), but peripheral organic groups in the shell give them several advantages over conventional inorganic particles with a wide variety of potential substituent groups attached (4). The choice of substituent groups not only provides POSS selective solubility in organic or aqueous solvents, but also the ability dispersed in many polymers and the specific chemical reactivity of different substituent groups that can be directly incorporated the POSS into polymer backbones or side groups or networks by covalent bonding (5)(6)(7)(8)(9)(10)(11). Therefore, the outer shell of POSS effectively controls the interaction between the POSS units and the surrounding matrix (12).…”

“…Therefore, the outer shell of POSS effectively controls the interaction between the POSS units and the surrounding matrix (12). What is more, the shell substituents could offer immense opportunities for synthesis of organic-inorganic hybrid copolymers (5)(6)(7)(8)(9)(10)(11). It has been reported that the introduction of POSS into polymers can distinctly enhance the native polymer properties in glass transition temperature (13)(14), decomposition temperature (15), surface hardness, mechanical properties, flammability resistance and oxidation resistance attributed to the inorganic octahedral cage structure of POSS (16)(17)(18).…”

Synthesis of composite latexes of polyhedral oligomeric silsesquioxane and fluorine containing poly(styrene‐acrylate) by emulsion copolymerization

“…To embed POSS into various polymer matrices, a lot of novel approaches have been developed, such as atom transfer radical polymerization (ATRP), reversible addition‐fragmentation chain transfer polymerization (RAFT), in situ solution polymerization, melt blending, radiation crosslink, and reactive blending . However, there are few works to fabricate the POSS‐contain polymers by using emulsion polymerization which is safe, convenient, and environment‐friendly …”
