标 题:Synthesis of nanofibers of polyaniline and substituted derivatives
发明人：EPSTEIN ARTHUR J; CHIOU NAN-RONG
权利人:OHIO STATE UNIVERISTY
摘要:Novel, simple methods are presented directed to the synthesis of nanofibers of polyaniline and substituted derivatives. The production of these fibers is achieved via various methods by controlling the concentration of aniline monomer or substituted aniline derivatives or an oxidant in the reaction medium and maintaining said concentration at a level much lower than conventional polyaniline synthesis methods. Methods are disclosed relating to the use of a permeable membrane to control the release of a monomer and/or oxidant as well as a bulk polymerization method.

摘要:A method for in-site synthesis of transparent conductive coating of poly(3,4-ethylenedioxythiophene)/nano silver hybrid on transparent substrate is provided. Transparent substrate with oxidant coating containing silver salt is immersed into 3,4-ethylenedioxythiophene (EDOT) solution. The oxidant turns EDOT monomer to poly(3,4-ethylenedioxythiophene) (PEDOT) coating on the transparent substrate; meanwhile, the silver salt itself is reduced to nano silver by the EDOT monomer, resulting in a nano silver-doped PEDOT coating. Thereby, a transparent conductive film made of PEDOT/nano silver coating on transparent substrate is obtained. The transparent conductive film with PEDOT/nano silver coating prepared in the present invention possesses the advantages of high electrical conductivity, optical transparency and environmental stability.

摘要:Provided are synthesis methods of polymerizing aniline or derivatives thereof. The production of polyaniline or polyaniline derivatives is controlled by the type of oxidant added in the reaction medium. The methods include the step of using a safe and environmentally friendly carbomethyl cellulose (CMC) or modified CMC as an oxidant in the polymerization reaction to produce polyaniline or aniline derivatives. Synthesis methods of producing O-CMC and O-CMC-S oxidants are also provided herein.

标题 :Gold micro- and nanotubes, their synthesis and use

摘要:Synthesis of gold microtubes and nanotubes suspendable in solution is presented. The synthesis is accomplished using an AAO template route, wherein a polymer tube is used as a sacrificial core. The synthesis produces hollow structures that consist of only gold. These nanostructures exhibit two SPR modes, which correspond to both the transverse and longitudinal modes. The mode assignment was confirmed by measuring SPR behavior as both aligned arrays and in solution. The performance of gold nanotubes as refractive index detectors was quantified and determined to be more sensitive than analogous solid nanorods prepared under identical conditions, and are among the most sensitive nanostructured plasmon sensors to date. Due to their intense and sensitive resonances in the NIR spectrum, these solution-suspendable nanoparticles have potential to be used as in vitro or in vivo sensors.

摘要:Process for the preparation of a benzohetero-[1,3]diazole compound disubstituted with brominated heteroaryl groups which comprises reacting at least one dihalogenated benzohetero[1,3]diazole compound with at least one brominated heteroaryl compound. Said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of compounds useful in the construction of solar concentrators (LSCs—“Luminescent Solar Concentratorsâ€?). Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used in the synthesis of photoactive polymers useful in the construction of photovoltaic devices (or solar devices) such as, for example, photovoltaic cells (or solar cells), photovoltaic modules (or solar modules), on both rigid or flexible supports. Furthermore, said benzohetero[1,3]diazole compound disubstituted with brominated heteroaryl groups can be advantageously used as precursor of monomeric units in the synthesis of semiconductr polymers.
