The rapid co‐assembly of graphene oxide (GO) nanosheets and a surfactant at the oil/water
(O/W) interface is harnessed to develop a new class of soft materials comprising continuous,
multilayer, interpenetrated, and tubular structures. The process uses a microfluidic approach
that enables interfacial complexation of two‐phase systems, herein, termed as “liquid
streaming”(LS). LS is demonstrated as a general method to design multifunctional soft
materials of specific hierarchical order and morphology, conveniently controlled by the …

In article number 2200220, Milad Kamkar, Orlando J. Rojas, and co-workers devise types of
biphasic soft materials featuring unique morphologies, eg, continuous, multilayer,
interpenetrated, and tubular structures. This is achieved by interfacial co-assembly of
nanomaterials and surfactants. These soft materials allow for the fabrication of structurally
tunable and stable ultra-flyweight aerogels with unique worm-like morphologies, consisting
of micro-and macro-scale porosity.
