DISSYMMETRIC PARTICLES (JANUS PARTICLES), AND METHOD FOR SYNTHESIZING SAME BY MEANS OF BIPOLAR ELECTROCHEMISTRY

摘要

Dissymmetric particles also called Janus particles of micron or submicron size and methods of synthesis of Janus particles by bipolar electrochemistry, based on substrates of isotropic or anisotropic shape. The particles include an electrically conductive substrate having at least a chemically and/or physically modified part by deposit of a layer of electrochemically depositable material, and a non-modified part. The particles are of isotropic shape, and the layer of electrochemically depositable material has a specific shape delimited by a precise contour.
