  • Patent number: 7045241
    Abstract: A monomer to produce polybenzimidazole is dissolved in polyphosphoric acid. For example, polysulfated phenylene sulfonic acid (acidic group-possessing polymer) is further dissolved in this solution. In this procedure, the acidic group-possessing polymer and the monomer are adsorbed to one another in accordance with the acid-base interaction. When the monomer is polymerized, for example, by means of dehydration polymerization in this state, then polybenzimidazole is synthesized, and the polybenzimidazole and the acidic group-possessing polymer are compatibilized with each other to produce a compatibilized polymer. When the compatibilized polymer is deposited as a solid, and the solid is separated from polyphosphoric acid, then the compatibilized polymer is obtained. A proton conductive solid polymer electrolyte as a final product is manufactured by forming the compatibilized polymer to have a predetermined shape.

  • Publication number: 20040171001
    Abstract: Novel methods allowing for the simple optical and electrochemical detection of double-stranded oligonucleotides are disclosed. The methods are rapid, selective and versatile. Advantageously, they do not require any chemical reaction on the probes or on the analytes since they are based on different electrostatic interactions between cationic poly (3-alkoxy-4-methylthiophene) derivatives and single-stranded or double-stranded (hibridized) oligonucleotides.

  • Publication number: 20040143091
    Abstract: Large contrast ratio and rapid switching laminated electrochromic (EC) polymer device includes transparent electrode, cathodic EC polymer, gel electrolyte, and counter-electrode. Preferably the cathodic EC polymer is a poly(3,4-propylenedioxythiophene) derivative, PProDOT-Me2. Counter-electrode is a conductive coating deposited on transparent substrate, with preferred coatings including gold and highly conductive carbon. Lithography and sputtering can be employed to pattern a gold layer, while screen printing can be employed to similarly pattern graphite. Empirical studies of preferred device indicate a color change of high contrast ratio of transmittance (>50% T) is rapidly (0.5−1 s) obtained upon applied 2.5V, repeatable to at least 10,000 times, as estimated by electrochemistry. Dual layer EC devices including PProDOT-Me2 are also disclosed, as are methods for synthesizing preferred EC polymers.
