20120112389 | ELECTROSPINNING MEMBRANE MACHINE IN WARP AND WEFT DIRECTIONS AND APPLICATION PROCESS THEREOF - The present invention relates to an electrospinning device for fabricating a membrane, in particular, to an electrospinning device for fabricating membrane by using spinnerets aligned in machine direction (MD) and transverse direction (TD) in a high-voltage DC electric field, and to method for using the same. In addition to producing a single-layer nanofiber membrane from a polymer composite, the electrospinning device according to the present invention can also conveniently produce a multilayer composite nanofiber membrane from more than one polymer composites. The electrospinning device comprises a control section, an electrospinning section and an ancillary section. The electrospinning section comprises a MD spinnerets set and a TD spinnerets set that are alternately arranged and moves above a membrane collecting device in a to-and-fro scanning manner so as to improve the evenness and strength of the obtained membrane. The high-voltage DC electric field is applied between the MD and TD spinnerets sets and a stainless steel conveyer belt for collecting the membrane. A polymer solution supplied to the MD and TD spinnerets sets is split into nanoflows under the action of the electric field, accumulated on the stainless steel conveyer belt to form a membrane and carried to a collecting roller to be collected. | 05-10-2012 |
20090156872 | METHOD FOR PHOTOCATALYTIC ISOMERIZATION OF 1,2-DIPHENYLETHYLENE ANALOGUES - The present invention relates to methods for accelerating the trans-cis isomerization of 1,2-diphenylethylene analogues by using photocatalyst. According to this invention, in the presence of polypyridyl platinum(II) complex with catalytic dosage, a solution containing trans-1,2-diphenylethylene analogues or mixture of cis- and trans-1,2-diphenylethylene analogues is irradiated by visible light to prepare product of cis-1,2-diphenylethylene analogues or product predominantly being cis-1,2-diphenylethylene analogues under inert gas atmosphere. This method has the advantages of fast reaction, high performance, easy separation of reaction system and recycle of the polypyridyl platinum (II) complexes. | 06-18-2009 |
