Optically Transparent Polymer Aerogels Via Controlled Radical Polymerization
نویسندگان
چکیده
We present a class of porous polymer monoliths with high visible light transmittance and low haze synthesized using nitroxide-mediated stable free radical polymerization (SFRP), form controlled polymerization, to suppress large pore structures. Such materials can find applications in thermally insulated windows. Aerogels adjustable optical properties were achieved by modulating the nitroxide equilibrium. Controlled resulted average widths <10 nm, porosities 43%, >60% (for 2.8 mm thickness). These results provide general design rules for clear, colorless polymers.

Synthesis of Polymer Grafted Magnetite Nanoparticle with the Highest Grafting Density via Controlled Radical Polymerization
The surface-initiated ATRP of benzyl methacrylate, methyl methacrylate, and styrene from magnetite nanoparticle is investigated, without the use of sacrificial (free) initiator in solution. It is observed that the grafting density obtained is related to the polymerization kinetics, being higher for faster polymerizing monomer. The grafting density was found to be nearly 2 chains/nm2for the rapi...
متن کاملDiarylbibenzofuranone-Based Dynamic Covalent Polymer Gels Prepared via Radical Polymerization and Subsequent Polymer Reaction
Diarylbibenzofuranone (DABBF) is a dynamic covalent bonding unit, which is in equilibrium with the corresponding radicals at room temperature, and polymers with DABBF linkages show notable properties such as self-healing. The preparation routes have been strictly limited, however, and no polymer with the linkages has been synthesized via radical polymerization because of the strong antioxidant ...

A facile synthetic route to prepare the dual-functional molecule, 2,5bis(40-carboxyphenyl)styrene, was developed. The esterification of this compound with chiral alcohols, that is, (S)-(þ)-sec-butanol/(R)-( )-sec-butanol, (S)-(þ)-secoctanol/(R)-( )-sec-octanol, and D-(þ)-menthol/L-( )-menthol, respectively, yielded three enantiomeric pairs of novel vinyl monomers, which underwent radical polyme...
متن کاملLiving Radical Polymerization via Organic Superbase Catalysis
Organic superbases reacted with alkyl iodides (R–I) to reversibly generate the corresponding alkyl radicals (R). Via this reaction, organic superbases were utilized as new and highly efficient organic catalysts in living radical polymerization. The superbase catalysts included guanidines, aminophosphines and phosphazenes. Low-polydispersity polymers (Mw/Mn = 1.1–1.4) were obtained up to high co...
