Through appropriate synthesis conditions, there are nearly ~100% of nanofibers formed in the bulk solution and of large arrays of aligned and oriented nanofibers formed on the surfaces of the substrates. For polyaniline nanofibers formed in the bulk solution, the diameters of nanofibers ranging from 20nm to 250nm are tunable via the selection of polymerization conditions. The lengths vary from sub-micrometers to several micrometers. A single nanofiber can be easily isolated from the agglomeration. X-ray diffraction patterns show that doped polyaniline nanofibers are substantially crystalline. Thin films deposited on a variety of sizes of the substrates shows highly uniform aligned and oriented polyaniline nanofibers that are perpendicular to the substrates. Those aligned and oriented uniform nanofibers have the tips ranging from 20nm to 40nm. UV/vis spectra of polyaniline nanofibers formed in the both bulk and substrates are consistent with nonfibrous polyaniline powders prepared by the conventional chemical synthesis. The nanofibrous morphology has no significant change when redoped/dedoped multiple times by the acid/base solutions. The formation mechanism of the nanofibers is discussed. Moreover, molecular modification of polyaniline nanostructures is also memtioned, thereby allowing preparation of nanofibers of a wide variety of polyaniline nanofibers and also control of the chemical, processing and electrical properties. Finally, polyaniline nanostructures offer wide, exciting and interesting applications, such as DNA stretching, surface modification (e.g. superhydrophilicity and superhydrophobicity), etc 2006-09-21 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1148485692 http://rave.ohiolink.edu/etdc/view?acc_num=osu1148485692 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
