[Chem Mater] Tough Biomimetic Hydrogels with High Fatigue Resistance Based on Self-Assembled Conjugated Polymer Belt Mesh Interlaced with a Polyelectrolyte Network
Supertough biomimetic hydrogels have been fabricated through in situ synthesis and guided assembling of positively charged conjugated polymer belts by using a parent poly(2-acrylamido-2-methylpropanesulfonic acid)/poly-(acrylamide) double network (PAMPS/PAAm DN) gel template. The interpenetrating structures of the poly(3,4-ethylenedioxythiophene) (PEDOT) belt mesh and PAMPS/PAAm host network have ...

[Ind. Eng. Chem. Res.] A Facile Bifunctional Strategy for Fabrication of Bioactive or Bioinert Functionalized Organic Surfaces via Amides-initiated Photochemical Reactions
Organic polymeric materials would exploit excellent
potential in biomedical field if their interfacial problem could be fully
resolved. A necessary prerequisite to this purpose often involves in the simple but effective synthesis of
bioactive surface to endow polymer surfaces with high reactivity
towards efficient biomolecules conjugation and bioinert surface to prevent
non-specific adsorption of ...

J. Mater. Chem. C, 2013,1, 5133-5141: Selective-swelling-induced porous block copolymers and their robust TiO2 replicas via atomic layer deposition for antireflective applications
We prepared antireflective nanoporous membranes by an extremely simple method which only involved the immersion of the optical substrates coated with amphiphilic block copolymers in hot ethanol for hours and a subsequent air drying process. Nanometer-sized pores were formed throughout the copolymer films through the swelling-induced pore generation mechanism. The pore structure and size and cons...

[J. Am. Chem. Soc.] Rare Earth Metal-Mediated Group-Transfer Polymerization: From Defined Polymer Microstructures to High-Precision Nano-Scaled Objects
Poly(2-isopropenyl-2-oxazoline) (PIPOx) and poly(2-vinylpyridine) (P2VP) have been efficiently synthesized using bis(cyclopentadienyl)methylytterbium (Cp2YbMe) as catalyst. The polymerizations of 2-isopropenyl-2-oxazoline (IPOx) and 2-vinylpyridine (2VP) follow a living group-transfer polymerization (GTP) mechanism, allowing a precise molecular-weight control of both polymers with very narrow mo...

J Mater Chem C, 2013, 2013,1, 1029-1036: Highly ordered TiO2 nanostructures by sequential vapour infiltration of block copolymer micellar films in an atomic layer deposition reactor
Atomic layer deposition (ALD) was used to controllably deliver precursors of TiO2 into the cores of micellar films of the amphiphilic block copolymer, poly(styrene-block-4-vinylpyridine) (PS-b-P4VP). Vaporized ALD precursors diffused through the PS corona and were exclusively enriched into the P4VP cores. Arrays of hexagonally arranged TiO2 nanoparticles were produced by burning off the polymeric ...

[Macromol. Chem. Phys.] Thermoresponsive Poly(2-Oxazoline) Molecular Brushes by Living Ionic Polymerization: Modulation of the Cloud Point by Random and Block Copolymer Pendant Chains
Molecular brushes (MBs) of poly(2-oxazoline)s were prepared by living anionic polymerization of 2-isopropenyl-2-oxazoline to form the backbone and living cationic ring-opening polymerization of 2- n -propyl-2-oxazoline and 2-methyl-2-oxazoline to form random and block copolymers. Their aqueous solutions displayed a distinct thermoresponsive behavior as a function of the side-chain composition an...

[J. POLYM. SCI. PART A-POLYM. CHEM.] Reverse atom transfer radical solution polymerization of methyl methacrylate under pulsed microwave irradiation
The reverse atom transfer radical polymerization (RATRP) of methyl methacrylate (MMA) was successfully carried out under pulsed microwave irradiation (PMI) at 69 °C with N,N-dimethylformamide as a solvent and with azobisisobutyronitrile (AIBN)/CuBr2/tetramethylethylenediamine as an initiation system. PMI resulted in a significant increase in the polymerization rate of RATRP. A 10.5% conversion...
