专利号:US-9637612-B2 优先权日:2013-09-20 标题 :Method for aligning high aspect ratio materials and compositions therefrom 发明人:MOASERI EHSAN; MAGHREBI MORTEZA; BANIADAM MAJID 权利人:FERDOWSI UNIV OF MASHHAD 摘要:A method for alignment of high aspect ratio materials (HARMs) within a liquid matrix by means of magnetic particles. The application of an external magnetic field creates a forced motion of the magnetic particles. This in turn leads to a laminar flow within the matrix which imposes a drag force on the HARMs, aligning the HARMs across the matrix. The used magnetic particles eventually accumulate at one end side of the matrix container and can be removed either by an incision or an extraction process. Unlike the previously proposed methods, there is no need for the magnetic particles to be attached either physically or chemically to the HARMs. Thus, the ultimate aligned HARMs are mostly pure and free of any magnetic particles. Once the matrix is a polymeric solution, the mentioned method is capable of synthesis of aligned HARMs-polymer composites, which exhibit improved mechanical and electrical properties.

Cuprous and ferric compounds react with sodium borate to form cuprous ferric oxide precipitates. Oxidizing a cuprous ferric oxide with an oxygen enhanced flame, synthesizes copper ferrite. The cuprous ferric oxide may be reduced to nanoparticle size via pulverization to produce copper ferrite nanoparticles.
