Ordered Assembly Of Nanostructure Zirconia

Reserch on the synthesize of inorganic material by microemulsion technology has the hotspot on material chemistry research. Nano-sized ZrO₂ shows many peculiar characters because of quantum effect ,surface effect ,etc. On the other, it can not be applied extensively for the shortcomings of coacervation easily and reclamation difficulty. Nano-sized ZrO₂ is assembled on some carriers with a certain form, which is one of the valid paths to resolve these problems. In this study ,We have prepared ZrO₂ nanopowder by microemulsion technology. On the basis of this, nano-sized ZrO₂ is assembled on PS sphere and ordered structure of ZrO₂ in micrometer scale is deposited on glass base.The main contents of this paper are showed as below:(1 ) Preliminarily study on the phase behavior above w/o microemulsion system of P-Octylpolyethylene glycol phenylether(OP)/ n-pentanol/ cyclohexane/Zr⁴⁺ solution and the influences of temperature,contration of Zr⁴⁺ and non-ionic surfactant OP etc .on the extent of microemulsion;(2)Nano-sized ZrO₂ is prepared by the microemulsion system of P-Octylpolyethylene glycol phenylether(OP)/ n-pentanol/ cyclohexane/Zr⁴⁺ solution. The influences of temperature,contration of Zr⁴⁺,pH, the temperature of calcination, the form of lavation and dryness on the sizes of particle are studied. The contrast on single-microemulsion and double-microemulsion are showed. Several influence factors are discussed on the congregation of nanopowders;(3)By the form of w/o microemulsion and LbL technology, nano-sized ZrO₂ is successfully assembled on PS sphere. Nanostruture PS/ ZrO₂ are characterized by means of TG, EDSand SEM;(4)On the basis of w/o microemulsion and gravity self-assembly technology, ordered-structures nano- ZrO₂ with different shapes are deposited on glass base. The influence of different conditions on ordered-stuctrue are studied. The mechanism of assembly on the ordered-structure is briefly discussed.
