New Material Design by Using Oxide Nano-Sheet

1)无机纳米片与导电聚合物的杂化我们成功地以无机纳米片与导电聚合物为原料制备了杂化纳米复合材料。我们以Mg_&lt；0.04&gt；Nb_&lt；1.66&gt；O_5，NbWO_6和SbP_O_8为无机纳米片，以聚(N-十八基-2-乙炔基溴化铵)、聚乙炔和聚苯胺为导电聚合物。2)层状氧化物的离子交换反应为了研究质子化层状化合物对高价大尺寸离子的离子交换性能，进行了各种质子化层状化合物与Bi^&lt；3+和gt；离子的离子交换反应。用质子化层状化合物的电荷密度讨论了Bi3+和Gt；离子的吸入量。另一方面，Na&lt；0.95&gt；Mo_2O_4中的Na~+离子试图与质子、碱金属和碱土金属离子进行离子交换，但质子化的化合物没有形成纳米片。通过水热反应合成了两种新的化合物[NH_4]_2Zr_2(OH)_2(PO_4)_2(HPO_4)，并对它们的软化学行为进行了研究。

We obtained the following results by this research project.1) Hybridization of inorganic nanosheets and conductive polymersWe have succeeded in preparation of hybrid nanocomposites from inorganic nanosheets and conductive polymers. We used Mg_<0.04>Nb _<1.66>O_5, NbWO_6 and SbP_O_8 as inorganic nanosheets, and poly(N-octadecyl-2-ethynylpyridinium bromide), polyacetylene and Polyaniline as conductive polymers.2) Ion-exchange reaction of layered oxidesIon-exchange reaction of various protonated layer compounds with Bi^<3+> ion was carried out in order to investigate ion-exchange property of protonated layer compounds for a high valence and large size ion. The uptake amount of Bi^<3+> ion was discussed by the charge density of the protonated layer compounds. On the other hand, Na^+ ion in Na_<0.95>Mo_2O_4 was attempted to ion-exchange with proton, alkaline and alkaline earth metal ions, however, the protonated compounds never formed nanosheets.3) Preparation of new layered oxidesNew layered zirconium phosphates, [enH_2]Zr (OH) (PO_4) (HPO_4) (en ; ethylene diamine) and [NH_4]_2Zr_2(OH)_2(PO_4)_2(HPO_4) were prepared by hydrothermal reaction, and their soft-chemical behaviors were now under investigation.
