Thermosensitive ZrP-PNIPAM Pickering Emulsifier and the Controlled-Release Behavior
Asymmetric
Janus and Gemini ZrP-PNIPAM monolayer nanoplates were obtained by
exfoliation of two-dimensional layered ZrP disks whose surface was
covalently modified with thermosensitive polymer PNIPAM. The nanoplates
largely reduced interfacial tension (IFT) of the oil/water interface
so that they were able to produce stable oil/water emulsions, and
the PNIPAM grafting either on the surface or the edge endowed the
nanoplates rapid temperature responsivity. The ZrP-PNIPAM nanoplates
proved to be thermosensitive Pickering emulsifiers for controlled-release
applications

Chiral Photonic Crystalline Microcapsules with Strict Monodispersity, Ultrahigh Thermal Stability, and Reversible Response
Tunable photonic
crystals (TPCs) reflecting selected wavelengths of visible light and
responding to external stimuli are widely applied to fabricate smart
optical devices. Chiral nematic liquid crystals (CNLCs) possessing
response to temperature, electric field, and magnetic field are considered
as one-dimensional TPCs. The encapsulation of CNLCs provides responsive
photonic devices with stand-alone macroscopic structure and excellent
processability. However, when CNLCs as cores are wrapped by polymeric
shells to form core–shell structured microcapsules, the polydispersity
of microcapsule size, the irregular spatial geometry, and the low
thermal stability inevitably result in a deterioration of the optical
performance and limited application at high temperatures. Herein,
a combination of microfluidic emulsification and interfacial polymerization
is employed to fabricate polymer wrapped photonic crystalline microcapsules
(PWPCMs). The sizes and reflected colors of PWPCMs can be simultaneously
controlled by adjusting the flow rates in the microfluidic chips.
PWPCMs possess strictly monodispersed sizes with coefficients of variation
less than 1%. The free-standing PWPCMs have high thermal stability.
The deformation temperature of PWPCMs is as high as 210 °C. The
colored PWPCMs also exhibit a reversible thermochromic property between
the chiral nematic phase and the isotropic phase. The highly stable
and tunable PWPCMs provide new opportunities for a wide range of photonic
applications, including smart optical window, tunable microlasers,
responsive microsensors, and various photonic devices
Aqueous Exfoliation of Graphite into Graphene Assisted by Sulfonyl Graphene Quantum Dots for Photonic Crystal Applications
We
investigate the π–π stacking of polyaromatic hydrocarbons
(PAHs) with graphene surfaces, showing that such interactions are
general across a wide range of PAH sizes and species, including graphene
quantum dots. We synthesized a series of graphene quantum dots with
sulfonyl, amino, and carboxylic functional groups and employed them
to exfoliate and disperse pristine graphene in water. We observed
that sulfonyl-functionalized graphene quantum dots were able to stabilize
the highest concentration of graphene in comparison to other functional
groups; this is consistent with prior findings by pyrene. The graphene
nanosheets prepared showed excellent colloidal stability, indicating
great potential for applications in electronics, solar cells, and
photonic displays which was demonstrated in this work
