Preparation Of Organic/Inorganic Nanocomposite Materials And Their Application For Organic Reactions

Ever since 1980, with the development and integrity of nanotechnology, the research on hybrid and composite nanomaterials has undoubtedly been an active field of special interest in the intersection of physics, chemistry, and materials science, of which inorganic/organic nanocomposites with a wide range of interesting properties increasingly become a burgeoning area. As an important embranchment of nanocomposites, these nanocomposites that incorporated noble metal nanoparticles with polymer nanofibers have the potential applications in various fields. Electrospinning has been extensively explored as a simple and versatile method for producing fibers from polymer solutions (or melts).In the second chapter, we successfully obtained inorganic/organic composite nanofibers (Au/PVA,Au/PVP and Au/PAM). These results of testing indicated that gold nanoparticles were well dispersed in the composite nanofibers.In the third chapter, acts as reducing reagent, we successfully obtained gold nanoparticles. And then, chitosan/PVP andβ-cyclodextrin/PVP composite nanofibers containing gold nanoparticles were prepared by electrospinning method. The product that was examed by various testing showed that gold nanoparticles could disperse uniformly with better morphologies in the composite nanofibers.In the fourth chapter, PMMA nanofibers have been obtained using electrospinning, and then we preparedβ-CD/PMMA composite nanofibers. On the base of, noble,metal (Au, Pt and Pd) nanoparticles were attached on the surface ofβ-CD/PMMA composite nanofibers. The product was approved by SEM, and we investigated the application of catalysts composite nanofibers for the organic reaction.In the fifth chapter, we preparedβ-CD/PS composite nanofibers using electrospinning method. And then, noble metal (Au, Pt and Pd) nanoparticles were attached on the surface ofβ-CD/PS composite nanofibers. The composite nanofibers containing noble metal nanoparticles were verified by the testing, and we first examined the ability of the composite nanofibers to promote the organic reaction.In the sixth chapter, firstly, theβ-CD/PAN composite nanofibers we prepared by electrospinning method. Secondly, we obtainedβ-CD/PAN composite nanofibers containing noble metal (Au, Pt and Pd) nanoparticles.Via the researching work of this dissertation, suggest a new strategy in the design and synthesize of novel inorganic/organic nanocomposites, and the products will have wide applications.
