  • Patent number: 11949137
    Abstract: The present invention belongs to the field of alkaline polymer electrolyte membranes, and relates to a comb-shaped structure polybenzimidazole anion exchange membrane with high conductivity and preparation method thereof. In the invention, firstly, polybenzimidazole is grafted with the non-cationic side chains to the max grafting rate to synthesize the de-protonated comb-shaped polybenzimidazole material, avoiding the N—H in benzimidazole forms ionic binding with cationic functional groups, which will reduce the reactivity and mobility of cationic groups; then react de-protonated comb-shaped polybenzimidazole with quaternization reagent to attach the pendent side chain with cationic functional groups, making it easy to aggregate to form ion clusters and hydrophilic/hydrophobic microphase separation. The anion exchange membrane prepared in this invention has excellent conductivity, mechanical properties and alkaline stability.

  • Patent number: 10633554
    Abstract: The present invention provides a surface modification method based on the polymerization and cross-linking solidification of dopamine and/or its derivatives, which belongs to the technical field about composite material fabrication. The principle of dopamine polymerization and the formation process of polydopamine coating layer are the foundation of the present invention. This innovative method is established after deeply analyzing the failure mechanism of polydopamine coating layer in severe environments, such as organic solvents and acidic/alkalic environments. The critical work is finding out an eligible cross-linking agent which could react with the active functional groups in polydopamine. After cross-linking reaction, the soluble low-molecular-weight dopamine oligomers could be transformed into the insoluble three-dimensional stereographic networks.

  • Patent number: 9372895
    Abstract: A method of forming a keyword based search query that uses a plurality of keywords, in which the keywords of the query are arranged into groups of purpose-related keywords, in which each keyword is associated with a designation of its relative importance. The keywords of a group may be identified manually by the searcher, or existing keywords in a group may be used to suggest or automatically add additional related keywords to the group. The keywords of a group need not be semantically related, but only related to a common purpose of the keyword group. Additional keywords can be suggested to the searcher, or automatically added to the groups. Suitable additional keywords may be identified by reference to previous searches in which the existing keywords were grouped with those additional keywords. Keywords may also be derived from text designated by the searcher, using all or portions of one or more documents or text blocks that the user identifies as describing a concept of interest to the searcher.

  • Patent number: 9170292
    Abstract: An insulation detection circuit suitable for detecting an insulation status between a high voltage power and a low voltage power of a vehicle is disclosed. The circuit includes a first energy storage unit, a second energy storage unit, a constant current unit, and a detection unit. The first energy storage unit is coupled to the high voltage power. The second energy storage unit is coupled between the first energy storage unit and the low voltage power. The constant current unit is coupled between the first energy storage unit and the second energy storage unit. The detection unit is coupled to the second energy storage unit for detecting a current change of the second energy storage unit. When the detection unit detects that current flowing through the second energy storage unit is smaller than a predetermined value, a detection signal representing that the insulation status is abnormal is outputted.
