[2] Organization of Nanoparticles

We intend to develop technology to fabricate thin film of ordered nanoparticles by arrangement and deposition on substrate.

We also intend to develop novel process for arrangement of nanoparticles in the gas phase using the attractive force between charged nanoparticles and counter-charged patterns on the substrate.

We aim to achieve high performance nanoparticles for use in different kinds of devices.

[3] Composite of Nanoparticles and Polymer

It is very difficult to mix nanoparticles with resin mechanically and to obtain uniform dispersion of nanoparticles in composites. We intend to develop technology to obtain a uniform dispersion of nanoparticles in the resin by (1) loosening the agglomeration of nanoparticles, and (2) treatment of nanoparticles with organic compounds, etc. Since the size of nanoparticles in the resin is smaller than the wavelength of visible light, the composites or films are transparent in the visible region in the figure shown below.

Through the expression of function/properties of nanoparticles and the application of basic technologies, it is possible to create composite materials, that can be used in a wide range of application fields having excellent thermal, electric, mechanical and photo-functional properties.
