摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

摘要:In particular, the invention relates to the synthesis of radiation-curable polyurethane/oligomeric urethane dispersions of anionic and cationic characters, containing neutralization techniques characterized by the selection of counter ions as monomers and/or agents which can be polymers acting as promoters under radiation, to a radiation polyurethane/oligomeric urethane synthesis method that enables the creation of radiation curable binder systems without using cosolvents, surfactants, emulsifiers, defoamers, stabilizers and additives, wherein all components of the radiation-curable binder systems can be polymerized.

标题:Synthesis of thioether containing trialkoxysilanes

摘要:The invention relates to a radical-initiated thiol-ene or thiol-yne “clickâ€? reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “clickâ€? reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.

标题 :Synthesis and 3D printing of photocurable colloids

摘要:Photocurable colloid binders are provided that overcome deficiencies associated with 3D printing of high molecular weight polymers via VAT photopolymerization. Methods of additive manufacturing are also provided using the binders. The approaches described herein effectively decouple the viscosity-molecular weight relationship by synthesizing and processing photo-reactive aqueous colloids that are sequestered within a photocrosslinkable scaffold. Sequestering polymers within discrete internal phases prevents inter-particle entanglement of the polymer chains, thus ensuring low viscosity. VP of polymer colloids results in a solid green body embedded with high molecular weight polymer particles. A post-processing heated drying step allows the polymers to coalesce and further entangle, forming a semi-interpenetrating network with mechanical performance of the high molecular weight material. The resins can further include inorganic particles such as silica and other ceramics, metal particles, and the like. The coalescence can result in the particles being encapsulated in polymer, yielding unique hybrid materials with tunable properties.

标 题:Ultrathin composite membranes
发明人：MARTIN CHARLES R; LIU CHAO

摘要:The present invention relates to a method of forming defect-free ultrathin film composite membranes by the photochemical synthesis of an ultrathin polymer film on the surface of a microporous support membrane. In one particular embodiment, the method entails placing a support membrane on a filter paper which is saturated with a solution of the desired monomer(s). The solution then wicks to the top of the membrane, covering the surface with a thin solution film, where it is subjected to irradiation by ultraviolet (UV) light to initiate the polymerization of the ultrathin polymer film. The rate of polymerization can be enhanced by adding a photoinitiator to the gas phase above the membrane or into solution with the monomer or monomers to induce radical polymerization. The method results in a defect-free ultrathin composite membrane. In addition, to minimize photon penetration depth and confine the polymerization predominantly to the membrane surface, the incident at which the UV light strikes the membrane surface is kept at an acute angle. The ultrathin film composite membranes can be used in a vast number of chemical separation processes, bioreactors and sensors, energy conversion and drug delivery systems.
