Polymerization-Induced Self-Assembly of Micelles Observed by Liquid Cell Transmission Electron Microscopy
In this paper, we
describe the use of liquid cell transmission
electron microscopy (LCTEM) for inducing and imaging the formation
of spherical micelles from amphiphilic block copolymers. Within the
irradiated region of the liquid cell, diblock copolymers were produced
which self-assembled, yielding a targeted spherical micellar phase
via polymerization-induced self-assembly (PISA). Critically, we demonstrate
that nanoparticle formation can be visualized in situ and that in
the presence of excess monomer, nanoparticle growth occurs to yield
sizes and morphologies consistent with standard PISA conditions. Experiments
were enabled by employing automated LCTEM sample preparation and by
analyzing LCTEM data with multi-object tracking algorithms designed
for the detection of low-contrast materials
