Effective Morphology Control in an Immiscible Crystalline/Crystalline Blend by Artificially Selected Viscoelastic Phase Separation Pathways
We investigated the interplay between viscoelastic phase separation (VPS) and crystallization in a dynamically asymmetric crystalline/crystalline polymer blend
system of poly(butylene succinate) (PBS)/poly(ethylene oxide) (PEO). The dynamic asymmetry came from the large molecular weight difference between the slow relaxing PEO and the fast relaxing PBS molecules. The evolution of networklike struc...

Soft Matter, 2011, 7, 8932-8941; Chemical modification of bioinspired superhydrophobic polystyrene surfaces to control cell attachment/proliferation
Surface chemistry is known to have a profound influence on cellular behavior. However, the cells'' responses on surfaces exhibiting extreme wettability values are not yet fully understood. In this work, bioinspired superhydrophobic polystyrene (PS) surfaces were produced by a phase separation method and the in vitro performance of three different cell lines (SaOs-2, L929 and ATDC5) was...

Chem. Commum, 2005, 1723-1725. Control over the responsive wettability of poly (N–isopropylacrylamide) film in a large extent by introducing an irresponsive molecule,
An irresponsive but very hydrophobic molecule—fluoroalkylsilane—can be used to cooperate with PNIPAAm to obtain tunable and enhancedly responsive wettability, and thus largely extend the application scope of PNIPAAm film.

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...

Time-dependent control of phase and morphology transformation of porous ZnO hollow microspheres by a facile one-step solution route
Porous ZnO hollow microspheres with a ZnO crystalline phase of PDF # 21-1486 have been prepared by a simple one-step solution route using the trisodium citrate as a shape-directing agent. FESEM, FT-IR, TEM and XRD were used to characterize the samples. Series of experiments showed the reaction time has a prominent impact on the phase and morphology transformation. At a point of the controlling g...

SoftMatter--Redox control of GPx catalytic activity through mediating self-assembly of Fmoc-phenyalanine selenide into switchable supramolecular architectures
Artificial enzymes capable of achieving tunable catalytic activity through stimuli control of enzymatic structure transition are of significance in biosensor and biomedicine research. Herein we report a novel smart glutathione peroxidise (GPx) mimic with modulatory catalytic activity based on redox-induced supramolecular self-assembly. First, an amphiphilic Fmoc-phenylalanine-based selenide was de...

[Sci. Adv. Mater.] Preparation and Surface Morphology Control of Self-assembled graphene oxide/chitosan Composite Membrane
Graphene oxide (GO)/chitosan composite membrane with thickness of several hundred nanometers was prepared through self-assembly at the air-liquid interface. Thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectra and X-ray photoelectron spectroscopy (XPS) were employed to study the interactions that induced the assembly of GO nanosheets and chitosan. The results show that the m...

[Macromolecules] From Polymer Sequence Control to Protein Recognition: Synthesis, Self-Assembly and Lectin Binding
A novel, highly efficient methodology to synthesize gradient
glycopolymers has been successfully developed involving concurrent
enzymatic monomer transformation and reversible addition–fragmentation
chain transfer (RAFT) polymerization. By synchronizing enzymatic monomer
transformation with polymerization, a continuous supply of the second
monomer (glycomonomer) is achieved during the...

[Langmuir] Control the Wettability of Poly(N-isopropylacrylamide-co-1-adamantan-1-ylmethyl acrylate) Modified Surfaces: The More Ada, the Bigger Impact?
Surface-initiated
SET-LRP was used to synthesize polymer brush containing
N-isopropylacrylamide and adamantyl acrylate using Cu(I)Cl/Me6-TREN as
precursor catalyst and isopropanol/H2O as solvent. Different reaction
conditions were explored to investigate the influence of different
parameters (reaction time, catalyst concentration, monomer
concentration) on the polymerization. Copolymers wi...
