  用于 CO2 和环氧化物共聚的表面活化戊二酸锌

  摘要：

  戊二酸锌 (ZnGA) 是一种很有前途的催化剂，它可以从 CO 2和环氧化物中形成聚合物，从而有助于 CO 2利用技术的发展和未来的可持续性发展。在聚合物工业中商业化 ZnGA 的障碍之一是其低催化活性。在这项研究中，我们引入了活化的二维 (2D) ZnGA 以提高其在聚合中的催化活性。用H 3 Co(CN) 6处理形貌受控的二维ZnGA ，制备了多孔颗粒型共改性ZnGA（Co-ZnGA）。二维 ZnGA 的形貌是 H 3 Co(CN) 6活化的先决条件. Co-ZnGA的催化性能通过各种环氧化物和CO 2的共聚来评价，并表现出855、1540、1190和148 g g-cat -1与环氧丙烷、1,2-环氧己烷、1,2的催化活性。 -环氧丁烷和氧化苯乙烯。本研究提供了一种使用二维 ZnGA 代替传统 ZnGA 来提高 CO 2聚合催化活性的新策略。

• Fabrication of biomimetic poly(propylene carbonate) scaffolds by using carbon dioxide as a solvent, monomer and foaming agent
  作者：Xia Zhong、Fariba Dehghani

  DOI：10.1039/c2gc35608b

  日期：——

  The aim of this study was to develop an environmentally friendly process for the fabrication of three dimensional (3D) biomimetic scaffolds from biodegradable poly(propylene carbonate) (PPC). Prior to production of scaffolds, PPC was synthesized using a one-pot process in which the zinc glutarate catalyst was first fabricated in a supercritical CO2 system. The scaffolds were then prepared by gas foaming/salt leaching followed by aminolysis and layer-by-layer (LBL) gelatin assembly on the surface. The pore size and interconnectivity were controlled by the variation of gas foaming process parameters such as temperature, CO2 pressure, depressurization rate and particle size of salt (NaCl). The pore size was within the range of 116 ± 53 to 418 ± 84 μm and the porosity was between 69.8 and 92.3%. The results of micro-CT scan analysis demonstrated that porosity and pore interconnectivity were enhanced by increasing the pore size. However, the compressive modulus of hydrated scaffolds was decreased from 380 ± 90 to 200 ± 50 kPa, when the pore size was increased from 232 ± 91 to 411 ± 108 μm. The results of fluorescence microscopy demonstrated that gelatin was uniformly deposited on the 3D scaffolds. Surface modification of hydrophobic PPC scaffolds substantially increased the fibroblast cells attachment, penetration, and proliferation. The results of this study demonstrated the feasibility of eliminating toxic organic solvents in the synthesis of a solid based catalyst and processing PPC polymer into tissue scaffolds. The clean technology developed will be of great value for large scale production of biodegradable PPC that can be used for many purposes such as packaging products and plastic bags. In addition, it was shown that PPC can be considered as an alternative biomaterial for tissue engineering applications.

  本研究旨在开发一种环境友好型工艺，利用可生物降解的聚（碳酸丙烯酯）（PPC）制造三维（3D）仿生支架。在生产支架之前，采用一锅法合成聚丙烯碳酸酯，首先在超临界二氧化碳系统中制造戊二酸锌催化剂。然后通过气体发泡/盐浸制备支架，接着进行氨解并在表面逐层（LBL）组装明胶。通过改变气发泡工艺参数，如温度、二氧化碳压力、减压速率和盐（氯化钠）的粒度，来控制孔径和互连性。孔径在 116 ± 53 至 418 ± 84 μm 之间，孔隙率在 69.8 至 92.3% 之间。显微 CT 扫描分析结果表明，孔隙率和孔隙互连性随着孔径的增大而增强。然而，当孔径从 232 ± 91 μm 增加到 411 ± 108 μm 时，水合支架的压缩模量从 380 ± 90 kPa 下降到 200 ± 50 kPa。荧光显微镜的结果表明，明胶均匀地沉积在三维支架上。疏水性 PPC 支架的表面改性大大提高了成纤维细胞的附着、穿透和增殖能力。这项研究的结果证明了在合成固体催化剂和将 PPC 聚合物加工成组织支架的过程中去除有毒有机溶剂的可行性。所开发的清洁技术对于大规模生产可生物降解的 PPC 具有重要价值，这种 PPC 可用于包装产品和塑料袋等多种用途。此外，研究还表明，PPC 可被视为组织工程应用的替代生物材料。

• X-ray absorption and NMR spectroscopic investigations of zinc glutarates prepared from various zinc sources and their catalytic activities in the copolymerization of carbon dioxide and propylene oxide

  The local and microstructures of zinc glutarates synthesized from various zinc sources were investigated by X-ray absorption and solid-state carbon-13 nuclear magnetic resonance spectroscopy, and related to their catalytic activities in the copolymerization of carbon dioxide and propylene oxide. It was found that the local structure around the Zn atoms of the zinc glutarate catalysts consists basically of tetrahedrally coordinated carboxyl oxygen atoms with a Zn-O bond distance in the range 1.95-1.96 Angstrom, and that the nearest neighbor Zn atom distance is 3.19-3.23 Angstrom. These results suggest that the catalysts have a network structure composed of layers interconnected by glutarate ligands. However, the first-shell structures of the catalysts tested are somewhat different, which might originate from differences in the catalysts' overall crystallinity and crystal quality (crystal size and perfection) produced by their different synthetic routes. The surface areas of the catalysts also varied with synthetic route. In the copolymerization, one catalyst with low surface area but the highest crystallinity and best crystal quality shows the highest catalytic activity, which is contrary to the usual expectation of increased catalytic activity with increased catalyst surface area. Therefore, the catalytic activities of zinc glutarates in the copolymerization seem to depend primarily on their morphological structures rather than on their surface areas. The surface areas of zinc glutarates may play a crucial role in improving the catalytic activity in the copolymerization when they first meet the morphological requirements (i.e., high crystallinity and crystal quality).
