我国科学家合成新型纳米材料碳141

中科院高能物理研究所赵宇亮等研究人员,日前利用一定能量的中子与C70分子相互作用,首次成功合成、分离、表征了单原子数目富勒烯分子C141。这一将核技术应用于新材料领域而取得的成果,为将来新一代中子源在材料科学研究中的应用提供了新思路。据介绍,富勒烯是一种由碳原子组成的纳米结构的球笼状分子。2个富勒烯碳笼连接起来,可以形成富勒烯二聚体。当2个富勒烯碳笼之间加入一个其他原子时,就可形成桥型富勒烯二聚体。而全碳富勒烯二聚体(C141)作为碳的又一种同素异形体和进行富勒烯聚合反应的起始物,在新型碳纳米材料研究中引起了极大关…

Metallkomplexkatalysatoren mit Phosphonsäureester-Phosphan-Liganden. I. Carbonylierung von Methanol mit Phosphonsäureester-Phosphan-Rhodiumkomplexen in der Flüssigphase

Metal Complex Catalysts with Phosphonic Ester Phosphine Ligands. I. Carbonylation of Methanol by Phosphonic Ester Phosphine Rhodium Complexes The treatment of technically available 2-(chloroethyl)phosphonic acid dimethylester ( 1 ) with diphenylphosphine and potassium-tert.-butylate affords 2-(diphenylphosphino)ethylphosphonic acid dimethylester ( 2a ) in a simple way. 2a can be used as a hemilabil complex ligand (by phosphine and phosphoryl group.) Rhodium complexes of the type (MeO)₂P(O)CH₂CH₂P(Ph)₂RhL₃ ( 3 ) were obtained from 2a and exhibit excellent catalytic properties in the liquid-phase carbonylation of methanol to acetic acid. Studies on other chelat-ligands did not confirm the exceptional increase of the activity by bisphosphinemonoxyd-ligands and the inhibition of the title reaction by bisphosphine-ligands already published.     

Influence of fullerenes on the thermal and flame-retardant properties of polymeric materials

At present, the application of fullerene in polymer materials has become an attractive issue. Fullerene can enhance the thermal and flame-retardant properties of polymers due to its high capacity to trap free radicals. Fullerene also has good synergistic effect with inorganic metal flame retardant, intumescent flame retardant, brominated flame retardant (BFR), clay, carbon nanotubes, graphene oxide, and so on. In this review, the impact and mechanism of fullerene and its derivatives on the thermal and flame-retardant properties of polymeric materials are discussed. And the prospect of fullerene in flame-retardant polymer composites is also briefly introduced by analyzing the research progress in the recent years. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.
