Triphasic Nanocolloids

摘要

One of the major challenges in current nanotechnology is the control of materials distribution at ultra-small length scales,potentially leading to the fabrication of multicompartmental nano-particles.One of the simplest versions thereof are two-sided particles,so-called Janus particles,which are believed to be of importance for designing active nanostructures or as functional elements in future device generations.As a first step toward the fabrication of multiphasic nanocolloids,we recently reported on the use of electrified co-jetting as an alternative approach toward Janus-type nanocolloids.The electrified co-jetting process exploits the manipulation of liquid jets with nanometer scale diameters created under the influence of electrohydrodynamic forces.The basic electrohydrodynamic process was applied to a broad range of materials,including polymer solutions,melts,blends,and dispersions.
