Tunable nanochannels through graphene oxide/polymer core-shell nanosheets for enhanced proton conductivity
Simultaneous manipulation of the topological
structure and chemical structure of the ionic nanochanels within solid electrolyte has
been proved a crucial but challenging task for the rational design of high-performance
electrochemical devices including proton exchange membrane fuel cell. Herein,
we present a novel approach to the construction of tunable nanochannels via direct assembly of graphene...

[RSC Advances] Exploring the potential of exfoliated ternary ultrathin Ti4AlN3 nanosheets for fabricating hybrid patterned polymer brushes
Since the discovery of graphene, two-dimensional
(2D) materials have been receiving increased attention. The quest for new 2D
materials with unique structure and special properties becomes urgent.Herein we report on the
preparation of a new kind of ternary 2D material, Ti4AlN3 nanosheets by liquid exfoliating of the corresponding laminated MAX phase. The
obtained Ti4AlN3 nanosheets, bearing abunda...

Redox-active cytocompatible phospholipid polymer hydrogels for three-dimensional electrical control of encapsulated living cells
Three-dimensional encapsulation of a living human cervical cancer HeLa cell in a redox-active
cytocompatible phospholipid polymer hydrogel and the regulation of cell functions with simple
bioelectrical stimulation were investigated. A redox-active and cytocompatible polymer based
on the water-soluble phospholipid polymer, poly(2-methacryloyloxyethyl phosphorylcholine
(MPC)-co-n-butyl...

Study of pH/ temperature dual stimuli-responsive nanogels with interpenetrating polymer network structure
Nanogels with interpenetrating polymer network (IPN) structure based on poly(N-isopropylacrylamide) (PNIPAM) and
poly(acrylic acid) (PAA) were synthesized by in situ polymerization of acrylic acid and N, N-methylenebisacrylamide within the PNIPAM nanogels. Their IPN structure was confirmed using transmission electron microscopy after staining by uranyl acetate. The temperature- or pH-dependent hy...

[2015][Macromolecules, 2015, 48 (12), 3941–3948]Optimization of Broad-Response and High-Detectivity Polymer Photodetectors by Bandgap Engineering of Weak Donor–Strong Acceptor Polymers
A series of weak donor–strong acceptor polymers containing two different electron-deficient units (diketopyrrolopyrrole and thienoisoindigo) are synthesized and used in broad-response and high-detectivity polymer photodetectors. By adjusting the composition ratio of the two acceptors, the absorption spectra, energy levels, molecular stacking, and film morphology are affected, which in turn infl...

The stability of covalently immobilization of TEMPO on the polymer surface through ionic liquid linkage: a comparative and model research.
Covalently immobilizing the active sites or ligands on a polymer surface is an efficient strategy to achieve a full use of expensive organic parts. In this work, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) was anchored onto polystyrene beads through an ether bond or an ionic liquid bridge. We quantitatively compared their thermal stabilities at nitrogen atmosphere and their chemical stabilities i...

An insight into the intensification of aqueous/organic phase reaction by the addition of magnetic polymer nanoparticles
The intensification mechanism of aqueous/organic
phase reaction by the addition of magnetic
polymer nanoparticles was investigated. To understand
how nanoparticles intensify the liquid-liquid (L-L)
reaction, three reaction enhancement
strategies of mechanical agitation (MA), the addition of magnetic
polymer nanoparticles (MPN) or phase transfer catalyst (PTC) were
compared in Montanari oxidation...

Improving Performance of Polymer Photovoltaic Devices Using Annealing-free Approach via Constructing Ordered Aggregations in Solution
Low crystalline order has been proved to be one of the main hindrances for achieving high performance devices based on thin films composed of crystallizable polymer. In this work, we use a facile method to substantially improve crystallinity of poly(3-hexylthiophene) (P3HT) in its pure or composite film via the construction of ordered precursors in the solution used for thin film de...

Epitaxy Assisted Creation of PCBM Nanocrystals and Its Application in Constructing Optimized Morphology for Bulk-Heterojunction Polymer Solar Cells
PCBM (a C60 derivative) is so far the most successful electron acceptor for bulk-heterojunction polymer photovoltaic (PV) cells. Here we present a novel method epitaxy-assisted creation of PCBM nanocrystals and their homogeneous distribution in the matrix using freshly cleaved mica sheet as the substrate. The highly matched epitaxy relationship between the unit cell of PCBM crystal ...
