摘要:我们展示了一种在非极性介质中制备聚合物/量子点(qd)纳米复合薄膜的高效而稳健的方法.通过采用基于硫醇-烯反应的光聚合法,制备出了对 Cdse@cds Qd 具有亲和力的含硫醇聚合物,并利用逐层组装法构建了聚合物/cdse@cds Qd 纳米复合薄膜.通过扫描电镜,电子显微镜,荧光光谱仪,热重分析,共聚焦激光扫描显微镜和时间分辨荧光光谱仪对聚合物/qd 纳米复合薄膜进行了表征.所制备的独立聚合物/qd 纳米复合薄膜具有较高的荧光强度,适度的透明度,非常好的光稳定性和热稳定性.我们进一步将光刻图案化与 Lbl 组装方法相结合,在柔性基底上制作了聚合物/cdse@cds Qd 纳米复合图案.这种多功能,简便的方法为设计基于聚合物/qd 纳米复合薄膜的新型光子器件提供了前景.

权利人:Monroe Mary Beth; PETRYK NATALIE M
摘要:A degradable polyurethane (PUr) having degradation rates useful for hemostatic dressings for controlling bleeding in traumatic wounds. Degradable PUrs may be synthesized from degradable monomers based on hydrolytically labile esters and oxidatively labile thioethers using rapid click-chemistry reactions. Monomers may include trimethylolpropane tris(3-mercaptopropionate) (TMPMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP), dipentaerythritol hexakis(3-mercaptopropionate) (DPEHMP) or 2,2'-(ethylenedioxy) diethanethiol reacted with hydroxyethyl acrylate, 3-buten-1-ol, 3-methyl-3-buten-1-ol, or 3-buten-2-ol. Synthesis of these monomers is rapid and has no byproducts or toxic catalysts that require removal, enabling polyol synthesis and immediate use in further polymerization

标 题 :Thiourethane polymers, method of synthesis thereof and use in fused filament fabrication printing
发明人：ELLSON GREGORY T; LUND BENJAMIN R; VOIT WALTER
权利人:BOARD OF REGENTS THE UNIV OF TEXAS; ADAPTIVE 3D TECH
摘要:A thermoplastic thiourethane polymer comprising a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. The first type of monomer includes two or more thiol functional groups and the type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anhydrous aprotic solvent-dissolved anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7.

摘要:A semi-crystalline thiourethane polymer. The semi-crystalline thiourethane polymer comprises a sequential chain of a first type of monomer covalently bonded to a second type of monomer via thiourethane linkages. Each of the first type of monomer includes two or more thiol functional groups and each of the second type of monomer includes two or more isocyanate functional groups. The first and second types of monomers are polymerized together in an anionic step-growth polymerization reaction that is catalyzed by a non-nucleophillic base having a pKa greater than 7, produced by photo-initiated decomposition of a photolatent base. A method of synthesizing, and polymer jetting and stereolithography methods of manufacturing a polymer part, are also disclosed.

摘要:A method of forming a voided polymer includes forming a polymerizable composition containing a polymer precursor and a solid templating agent, forming a coating of the polymerizable composition, processing the coating to form a cured polymer material having a solid phase in a plurality of defined regions, and removing at least a portion of the solid phase from the cured polymer material to form a voided polymer layer.

摘要:Compositions and processes for development of sustainable materials based upon a method of thermoplastic polymer recycling with a solvent that is also a monomer for renewable polymer synthesis. By combining petroleum-derived polymers with bio-based monomer feedstocks, biphasic, blended polymer products are produced and are shown to exhibit facile tunability of physical and material properties. This one-pot, solvent-based recycling approach yields neat recycled products without the use of solvent evaporation or solute precipitation, and the functional utility of the resulting polymer blends greatly exceeds that of either homopolymer alone.
