Patent number: 7943066Abstract: The present invention provides electrically conductive paper composites prepared from cellulose fibers modified to bind a conducting polymer to a surface of the cellulose fibers and mixing these with unmodified cellulose fibers and forming paper products from the composite. Conducting paper composites so formed were investigated for their conductivity and strength properties as a function of monomer dosage or percentage of modified fibers in the mixture and for the composites it was found that less monomer (i.e. conductive polymer) was needed to achieve the same conductivity obtained from conducting paper made from only the modified cellulose. A higher tensile strength was obtained with the composite conducting paper than was attained with conducting paper made from only the modified cellulose. The electrically conductive paper composites may also be prepared from cellulose fibers mixed with particulate fillers modified to bind a conducting polymer to a surface of the particulate fillers.Type: GrantFiled: October 4, 2007Date of Patent: May 17, 2011Assignee: The University of New BrunswickInventors: Yonghao Ni, Bin Huang, Guojun Kang

Publication number: 20100323233Abstract: The present invention relates to electrical separators and to a process for making them. An electrical separator is a separator used in batteries and other arrangements in which electrodes have to be separated from each other while maintaining ion conductivity for example. The separator is preferably a thin porous insulating material possessing high ion permeability, good mechanical strength and long-term stability to the chemicals and solvents used in the system, for example in the electrolyte of the battery. In batteries, the separator should fully electrically insulate the cathode from the anode. Moreover, the separator has to be permanently elastic and to follow movements in the system, for example in the electrode pack in the course of charging and discharging.Type: ApplicationFiled: August 30, 2010Publication date: December 23, 2010Applicant: EVONIK DEGUSSA GmbHInventors: Volker Hennige, Christian Hying, Gerhard Hörpel

Publication number: 20100295633Abstract: Disclosed herein is an electromagnetic bandgap (EBG) pattern structure, including: a nonconductive substrate; and a pattern assembly formed on the substrate and including regularly arranged closed-loop patterns and open-loop patterns both of which are made of a conductive material. The EBG pattern structure is advantageous in that it can be used to manufacture new security products by applying its frequency characteristics to securities or IDs and in that it can be variously used in security technologies for preventing forgery and alteration because various security codes can be created by adjusting the variables of its EBG pattern.Type: ApplicationFiled: May 20, 2010Publication date: November 25, 2010Inventors: Jong Won YU, Won Gyu Lim, Hyeong Seok Jang, Dong Hoon Shin, Jin Ho Ryu, Hyun Mi Kim, Won Gyun Choe
