    Abstract

    In this report, we will describe about control of structures of two-dimensional patterns of nanoparticles. When the glass substrate was dipped into and withdrawn from highly concentrated dispersion of nanoparticles, stripe-crack patterns were formed parallel to the receding direction. The patterned assembly of nanoparticles was spontaneously removed from glass substrate. From scanning electron microscopy (SEM), it was clear that the assembly of silica particles had strap-like structure. The thickness of the assembly consisting of silica particles could be controlled by deposition speed and size of particles.
