Abstract

The present invention provides for a number of interrelated methods for the production of random and ordered arrays of particles as well as films containing the same. In another aspect, the present invention relates to the random and ordered arrays of particles and films prepared therefrom. The ordered arrays are obtained by the use of ferrofluid compositions which may be curable, solidifiable or non-curing/non-solidifiable. Especially preferred arrays and films contain electrically conductive particles for use in electronic applications for effecting contact between leads or pads.
