| 20100130625 | PROTON EXCHANGE MEMBRANE AND METHOD FOR MANUFACTURING THE SAME - A proton exchange membrane and method for formation the same is disclosed. When forming the proton exchange membrane, first, a bismaleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluorethylene copolymer (Nafion) aqueous solution is replaced with dimethyl acetamide (DMAc). 10 to 15 parts by weight of the hyper-branched polymer is added to 90 to 85 parts by weight of the Nafion in the DMAc solution, stood and heated to 50° C. for inter-penetration of the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent to complete formation of the proton exchange membrane. | 05-27-2010 |

| 20100167102 | INTER-PENETRATED PROTON EXCHANGE MEMBRANE, METHOD FOR MANUFACTURING THE SAME, AND PROTON EXCHANGE MEMBRANE FUEL CELL UTILIZING THE SAME - The disclosed forms a proton exchange membrane. First, multi-maleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluorethylene copolymer (Nafion) aqueous solution is replaced from water with dimethyl acetamide (DMAc). 10 to 20 parts by weight of the hyper-branched polymer is added to the 90 to 80 parts by weight of the Nafion in a DMAc solution, stood and heated to 50° C. to inter-penetrate the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent for completing an inter-penetrated proton exchange membrane. | 07-01-2010 |
| 20110033773 | Modified Hyper-Branched Polymer and Proton Exchange Membrane Applied with the Same, and Method for Manufacturing the Proton Exchange Membrane - A proton exchange membrane comprising modified hyper-branched polymer is disclosed. The proton exchange membrane includes 85-90 wt % of sulfonated tetrafluorethylene copolymer and 15-10 wt % of modified hyper-branched polymer. The modified hyper-branched polymer comprises the bismaleimide (BMI)-based hyper-branched polymer, and parts of the chain ends of the hyper-branched polymer are sulfonated by the sulfonic compound. Also, the modified hyper-branched polymer and sulfonated tetrafluorethylene copolymer are interpenetrated to form an interpenetrating polymer. Furthermore, the modification step could be performed before or after forming the interpenetrating polymer. For example, the sulfonation is proceeded after forming the interpenetrating polymer. Alternatively, the sulfonation of the hyper-branched polymer could be proceeded before the formation of the interpenetrating polymer. | 02-10-2011 |

| 20100140099 | METHOD AND APPARATUS FOR ELECTROCHEMICAL PLATING SEMICONDUCTOR WAFERS - A method of electroplating conductive material on semiconductor wafers controls undesirable surface defects by reducing the electroplating current as the wafer is being initially immersed in a plating bath. Further defect reduction and improved bottom up plating of vias is achieved by applying a static charge on the wafer before it is immersed in the bath, in order to enhance bath accelerators used to control the plating rate. The static charge is applied to the wafer using a supplemental electrode disposed outside the plating bath. | 06-10-2010 |
