DISSYMETRIC PARTICLES (JANUS PARTICLES) AND PROCESS FOR THE SYNTHESIS THEREOF BY BIPOLAR ELECTROCHEMISTRY.

摘要

The present invention relates to asymmetric particles also called Janus particles of submicron or micron size comprising an electrically conductive substrate (1) having at least one part (11, 12) chemically and / or physically modified by deposition of a layer of electro-magnetic material. chemically removable, and an unmodified portion (13). According to the invention, these particles are of isotropic form, and the layer of electro-chemically removable material has a specific shape delimited by a precise contour. The present invention also relates to a process for synthesizing Janus particles by bipolar electrochemistry, from substrates of isotropic or anisotropic form.
