Crystallization Behavior of Nano-structured PEO-b-PS/PPO Blends
关键字：Crystallization,Behavior,Nano,structured,PEO,PPO,Blends,
It was suggested and demonstrated that block or graft copolymers could be harnessed in a much more powerful way to structure blends down to molecular scale, that is, a few tens of nanometers[1].

【42 RSC Advances】 Interplay between the compatibilization of polyethylene-graft-polystyrene and the composition of LLDPE/PS blends in the foaming behaviour
Polyethylene-g-polystyrene (PE-g-PS) copolymers, which were prepared by the combination of the ROMP and ATRP method, were utilized to compatibilize LLDPE/PS blends. On one hand, the effect of PE-g-PS on the morphologies of LLDPE/PS blends was investigated. On the other hand, the influences of branch length and added amount of PE-g-PS on the cell morphology of foamed LLDPE/PS blends with different ...

【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...

6.【 Polymer】 Effect of Spreading Solvents on Langmuir Monolayers and Langmuir–Blodgett Films of PS-b-P2VP
Langmuir monolayers of polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) diblock copolymers (with the same PS block length and different P2VP block lengths) formed at the air/water interface were characterized with the Langmuir film balance technique. Nonselective and selective solvents were used to spread the samples on the water surface and the spreading solvents showed large effect on the s...

Facile Synthesis of Mono-Dispersed Polystyrene (PS)/Ag Composite Microspheres via Modified Chemical Reduction
A modified method based on in situ chemical reduction was developed to prepare mono-dispersed polystyrene/silver (PS/Ag) composite microspheres. In this approach; mono-dispersed PS microspheres were synthesized through dispersion polymerization using poly-vinylpyrrolidone (PVP) as a dispersant at first. Then, poly-dopamine (PDA) was fabricated to functionally modify the surfaces of PS mi...

Solvothermal synthesis of hierarchical Eu2O3 nanostructures templated by PS-b-PMAA: morphology control via simple variation of water contents.
A new method to synthesize hierarchical Eu203 nanostructures via a solvothermal process in N,N''''-dimethyl formamide (DMF) templated by an ionic amphiphilic diblock copolymer polystyrene-block-poly (methacrylic acid) (PS-b一PMAA) has been developed. By simply varying the mass ratio of HZO over DMF from 0 to 20 wt% in the polymer-salt mixed solution, a series of Eu203 morphologies including worm...
