Crystallinity Tunes Permeability of Polymer Nanocapsules
Permeability
is the key property of nanocapsules because it dictates
the release rate of encapsulated payloads. Herein, we engineer the
crystallinity of polymers confined in the shell of nanocapsules. Nanocapsules
with crystalline shells are formed from polyurea and polyphosphoester.
The thermal properties, such as crystallization temperature and degree
of crystallinity, are different from the bulk. The degree of crystallinity
is used to control the shell permeability and, therefore, the release
of encapsulated payloads, such as fluorescent dyes, typically used
as model components for biomedical applications
