In an exemplary embodiment, a method includes reacting a fluoromonomer “M†with a chain transfer agent of the formula X—Y or Y—X—Y, wherein X represents a C 1 -C 3 hydrocarbon, a C 1 -C 6 hydrofluorocarbon, C 1 -C 6 hydrochlorofluorocarbon, or C 1 -C 6 fluorocarbon and Y represents iodine or bromine, in the presence of a radical initiator, to form a macro-initiator of the formula: X-poly(M)-Y or Y-poly(M)-X-poly(M)-Y, wherein poly(M) represents a polymer of the fluoromonomer. The method further includes reacting the macro-initiator with chlorotrifluoroethylene (CTFE) in the presence of a radical initiator to form a diblock or a triblock CTFE-based block copolymer of the formula: X-poly(M)-block-poly(CTFE) or PCTFE-block-poly(M)-X-poly(M)-block-PCTFE.

专利号:US-9867899-B2 优先权日:2010-05-24 标题 :Reinforced adhesive complex coacervates and methods of making and using thereof 发明人:STEWART RUSSELL J 权利人:UNIV UTAH RES FOUND 摘要:Described herein is the synthesis of reinforced adhesive complex coacervates and their use thereof. The reinforced adhesive complex coacervates are composed of (a) at least one polycation, (b) at least one polyanion, and (c) a reinforcing component. The adhesive complex coacervates described herein can be subsequently cured to produce strong, cohesive adhesives. The reinforced adhesive complex coacervates have several desirable features when compared to conventional adhesives. The reinforced adhesive complex coacervates are effective in wet or underwater applications. The reinforced adhesive complex coacervates described herein, being phase separated from water, can be applied underwater without dissolving or dispersing into the water. The reinforced adhesive complex coacervates have numerous biological applications as bioadhesives and bioactive delivery devices. In particular, the reinforced adhesive complex coacervates described herein are particularly useful in underwater applications and situations where water is present such as, for example, wet tissues in physiological conditions.
专利号:US-9561493-B2 优先权日:2010-05-11 标题 :Synthesis of pyrochlore nanostructures and uses thereof 发明人:SUBRAMANIAN VAIDYANATHAN; MURUGESAN SANKARAN 权利人:SUBRAMANIAN VAIDYANATHAN; MURUGESAN SANKARAN; UNIV NEVADA RENO 摘要:A template-free reverse micelle (RM) based method is used to synthesize pyrochlore nanostructures having photocatalytic activity. In one embodiment, the method includes separately mixing together a first acid stabilized aqueous solution including pyrochlore precursor A and a second acid stabilized aqueous solution including pyrochlore precursor B with an organic solution including a surfactant to form an oil-in-water emulsion. Next, equimolar solutions of the first and second acid stabilized oil-in-water emulsions are mixed together. Then, the mixture of the first and second acid stabilized oil-in-water emulsion is treated with a base to produce a precipitate including pyrochlore precursors A and B. After which, the precipitate is dried to remove volatiles. The precipitate is then calcined in the presence of oxygen to form a pyrochlore nanostructure, such as a bismuth titanate (Bi 2 Ti 2 O 7 ) pyrochlore nanorod. The method of synthesizing the pyrochlore nanorod is template-free.
