SEM Technique Analyzing Tungsten Trioxide Nanowire

Structural Equation Modeling is a blend of multivariate statistical techniques of factor analysis and path analysis. Its strength lies in the quantitative study of the interactive relations among multiple variables. In nearly three decades, SEM is used in a large number of social and behavioral sciences, in the recent years; it has been increasingly used in market research. By SEM technique analyze of tungsten trioxide nanowire, we have a better understand that the impact of changes in external factors caused by the topography. It can be analyzed by the precursor and the reaction temperature.

Nanowires may be defined as having in the transverse direction that is limited to one-dimensional structure at 100 nm (without longitudinal limit). Nanowire suspension means the end of the nanowire under vacuum. Depending on the composition of the material, the nanowire can be divided into different types, including metallic nanowires, nanowires and the insulator semiconductor nanowires.

The preparation of tungsten trioxide nanowire can be divided in three steps. Firstly, obtaining the diameter about 200-500nm tungsten trioxide nanowire, the length about 5-10μu with 1.3g of sodium tungstate reaction in the same conditions. Secondly, we can also study its effect on the appearance of the tungsten trioxide nanowires synthesized by controlling the reaction temperature. Finally, we obtain tungsten trioxide nanowires in the uniform conditions that the reaction time is 32h at 240 ℃, and its diameter is 200-500nm, its length is about 5-10μm.
