专利号:US-7713446-B2 优先权日:2004-06-28 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.

专利号:US-6737504-B2 优先权日:2001-07-30 标 题 :Synthesis of substituted poly(aniline)s 发明人:FREUND MICHAEL S; SHOJI EIICHI 权利人:CALIFORNIA INST OF TECHN 摘要:A method for preparing a wide range of substituted poly(aniline)s from a single precursor is described. The method uses a variety of reactions, including a boron activation/electrophilic displacement reaction resulting in ipso-substitution. The ability to tune the properties of poly(aniline) through the generation of new structures is useful in numerous fields ranging from polymer-based electronics to sensors.
