【23 Chemical Journal of Chinese Universities-Chinese】 Preparation and characterization of PS-b-P2VP/Fe3O4 nanocomposites
Oleic acid modified Fe3O4 nanoparticles(OA-Fe3O4) with uniform particle size were blended with polystyrene-b-poly (2-vinyl pyridine) (PS-b-P2VP) that had micro-phase separation structure using solution-mixing method. The resultant PS-b-P2VP/Fe3O4 nanocomposites were superparamagnetic. The results showed that OA-Fe3O4 nanoparticles were dispersed in the PS phase of PS-b-P2VP, when the mass fraction...

【29 Physical Chemistry Chemical Physics】 Creation of nanoholes in carbon nanotubes with improved capacities for lithium ion battery
The porous carbon nanotubes were selectively prepared from the pristine carbon nanotubes. The surface of carbon nanotubes was firstly functionalized with Fe2O3 nanoparticles and subsequent heat treatment induced CNT etching. After removal of Fe2O3 nanoparticles, mesopores were formed in carbon nanotubes and thus porous structure was obtained. The obtained material of porous carbon nanotubes with h...

【17 Chemical Engineering Journal 】 Effect of the added amount of organically-modified montmorillonite on the catalytic carbonization of polypropylene into cup-stacked carbon nanotubes
For the first time, cup-stacked carbon nanotubes (CS-CNTs) with high quality were efficiently synthesized by a one-pot approach through the carbonization of polypropylene (PP) under the combined catalysis of organically-modified montmorillonite (OMMT)/NiO. The effects of the added amount of OMMT on the yield, morphology, microstructure, phase structure and thermal stability of carbon nanomaterials...

A novel chemical reduction method to fabricate tunable selenium nanosphere and nanobelt based on cellulose nanocrystals
A novel chemical reduction method was reported to prepare tunable spherical or belted morphologies of nano-selenium (Se) based on cellulose nanocrystal (CNC). The homogeneous Se nanospheres with size of about 36?nm can be found for Se-Sphere-12H by adding ascorbic acid (VC) as assisted reducing agent. The Se nanobelt with a length of about 800?nm can be observed for Se-Belt-12H through one-pot rea...

【[Frontiers of Chemical Science and Engineering]】Laser Ablation of Block Copolymers with Hydrogen-Bonded Azobenzene Derivatives
We investigated laser interference ablation
of block copolymer supramolecular assemblies. Supramolecular assemblies
(PS-b-P4VP(AzoR)) are fabricated by hydrogen-bonding azobenzene derivatives
(AzoR) to poly(4-vinyl pyridine) blocks of polystyrene-block-poly(4-vinyl
pyridine) (PS-b-P4VP). PS-b-P4VP(AzoR) forms phase separated nanostructures
with a period of ~75-105 nm. A second len...

Chemical cross-linked polyvinyl alcohol/cellulose nanocrystal composite films with high structural stability by spraying Fenton reagent as initiator
Cross-linked polyvinyl alcohol (PVA) composite films with high structural stability were prepared by free radical copolymerization between cellulose nanocrystal (CNC) and maleic anhydride (MAH) modified PVA through spraying Fenton free radical as initiator. The influence of chemical cross-linked and physical network structure on mechanical, thermal and water absorption properties of the composit...

50. [Chemical Engineering Journal] Tough and pH-sensitive hydroxypropyl guar gum/polyacrylamide hybrid double-network hydrogel
Using a facile two-step method, the researchers synthesized a pH-responsive double-network (DN) hydrogel with high strength and toughness, consisting of a B(OH)4? linked hydroxypropyl guar gum (HPG) network and a covalently cross-linked polyacrylamide (PAAm) network. The mechanical strength of HPG/PAAm DN gel was investigated as a function of synthesis conditions, HPG content, sodium borate conc...

56. [European Polymer Journal] The role of chemical and physical crosslinking in different deformation stages of hybrid hydrogels
Hybrid crosslinking hydrogels have exhibited excellent mechanical properties, however, the relationship between chemical and physical crosslinking in the various deformation stages is still indistinct. Here, we have explored a novel hybrid hydrogel by inducing low density of chemical crosslinking into latex particle hydrogels (LP-Gel), in which latex particles act as physical crosslinking center...

An Insight into Formation Mechanism of Rapid Chemical Co-Precipitation for Synthesizing Yttrium Iron Garnet Nano Powders
The rapid chemical co-precipitation method is supposed to be a stable
way to synthesize high quality cubic yttrium iron garnet (YIG)
nanopowders. In this paper, focusing on clarifying its formation
mechanism, the thermal behaviors and the elemental distributions of the
chemical co-precipitated precursors have been analyzed by simultaneous
differential scanning calorim...
