摘要:
A mobile terminal includes a terminal main body, a circuit board, an antenna device and a connecting portion. The terminal main body has a plurality of members. The circuit board and an antenna device are built in the terminal main body so as to be spaced apart from each other. The connecting portion electrically connects the circuit board and the antenna device to each other. In the mobile terminal, the connecting portion is a conductive pattern formed on one surface of at least one of the members defining an internal space of the terminal main body.

A benzoxazine-based monomer includes a halogen atom-containing functional group and a nitrogen-containing heterocyclic group. A polymer formed from the benzoxazine-based monomer may be used in an electrode for a fuel cell and electrolyte membrane for a fuel cell.
摘要:
A method for the production of mechanically stabilized polyazole polymers, comprising the following steps: a) providing a membrane comprising i.) polyazoles with at least one amino group in a repeating unit except the ones obtainable by reacting aromatic and/or heteroaromatic diaminocarboxylic acids, ii.) at least one strong acid and iii.) at least one stabilizing reagent, the total content of stabilizing reagents in the membrane being within the range of from 0.01 to 30% by weight, b) performing the stabilization reaction in the membrane, immediately or in a subsequent processing step of the membrane, c) if appropriate, additionally doping the membrane obtained in accordance with step b) with a strong acid or concentrating the present strong acid further by removal of present water, wherein the stabilizing agent comprises at least one oxazine-based compound. The polyazole polymer membranes thus obtainable are in particular characterized by a high conductivity and a very good mechanical stability. Therefore, they are in particular suited for applications in fuel cells.
