A process for the preparation of a three-dimensional accumulation of particles, which are arranged in rows

摘要

A method of producing three dimensional ordered arrays of particles. The method may be used for the preparation of nanocomposite materials with highly periodic structures. More particularly the invention provides a method of producing three dimensional arrays based on applying a controlled oscillatory motion to settling dispersions of colloid particles. The controlled oscillatory motion is characterized by G=Aφ2/g, wherein g is the gravitational constant, A is the displacement and φ is angular frequency. G is maintained in the desired range by varying values of A within an effective range of displacements and within ω an effective range of frequencies.
