[Journal of Alloys and Compounds]Controlled shell on nanoparticles as a tool to regulate the properties of immobilized molecules
Tuning functions of organic molecules is a remaining challenge in versatile applications. Here, we demonstrated the pKa of 11- mercaptoundecanoic acid can be subtly tuned by the gold shell thickness of Fe2O3@Au core-shell nanoparticles. Based on titration results, the rebalance of the electrostatic and vdW interactions on nanoparticles was proposed as a mechanism for regulating the pKa of 11-mer...

Chemoenzymatic Synthesis of Amphiphilic Core–Shell TMP-(PCL-b-PGMA2)3 Star-Block Copolymer
A novel well-defined amphiphilic Core–Shell star-block copolymer was synthesized from trimethylolpropane, -caprolactone, and glycidyl methacrylate by a combination of enzymatic ring-opening polymerization and atom transfer radical polymerization. The structure and molecular weight of the macroinitiator and the star-block copolymer were confirmed by means of nuclear magnetic resonance and gel p...

Induced SERS activity in Ag@SiO2/Ag core-shell nanosphere arrays with tunable interior insulator
The recently reported shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) is considered as the next generation of advanced spectroscopy for its surface and molecular generality. With the aim to utilize the virtues of shell-isolated strategy and advance the SHINERS technique, we introduce a silane-based rapid synthesis method of silica-coating Au nanorods (Au@SiO2 NRs) with manoeuvrab...

Morphology Evolution of Polystyrene-core/Poly(N-isopropylacrylamide)-shell Microgel Synthesized by One-pot Emulsion Polymerization
One-pot emulsion polymerization with macroinitiator is supposed to be a robust, facile
way to synthesize well-defined core-shell nanoparticles with fixed shell thickness. To testify this, we calibrated the temperature dependence morphology evolution of polystyrene (PS) core/poly(N-isopropylacrylamide) (PNIPAM) shell microgel synthesized by one-pot emulsion polymerization with PNIPAM-RAFT as m...

Preparation of Core–Shell Nanofi bers with Selectively Localized CNTs from Shish Kebab-like Hierarchical Composite Micelles
A novel and facile bottom-up strategy for preparing core-shell nanofi bers with selectively localized carbon nanotubes is developed using hierarchical composite micelles of crystalline-coil copolymer and carbon nanotubes as the building blocks. An amphiphilic di-block copolymer of poly ( p -dioxanone) (PPDO) and PEG (polyethylene glycol) functionalized with pyrene moieties at...

38. Super-tough, ultra-stretchable and strongly compressive hydrogels with core–shell latex particles inducing efficient aggregation of hydrophobic chains
Toughness, strechability and compressibility for hydrogels were ordinarily balanced for their use as mechanically responsive materials. For example, macromolecular microsphere composite hydrogels with chemical crosslinking exhibited excellent compression strength and strechability, but poor tensile stress. Here, a novel strategy for the preparation of a super-tough, ultra-stretchable and ...

21. Co-toughened Polystyrene by Submicrometer-Sized Core?Shell Rubber Particles and Micrometer-Sized Salami Rubber Particles
A series of submicrometer-sized polybutadiene (PB) rubber particles with different diameters ranging from 100 to 450 nm were prepared via an emulsion polymerization. Subsequently, core.shell polybutadiene-graf t-polystyrene (PB-g-PS) particles were synthesized using a redox initiator system (cumene hydroperoxide and ferrous sulfate) by an emulsion grafting polymerization...

15. Toughening polystyrene by core–shell grafting copolymer polybutadiene-graft-polystyrene with potassium persulfate as initiator
Core–shell polybutadiene-graft-polystyrene rubber particles with different ratios of polybutadiene core to polystyrene shell were synthesized by an emulsion polymerization using K2S2O8 as an initiator. Then the core–shell rubber particles were blended with PS to prepare PS/PB-g-PS. The rubber particles with a size of 0.3–0.5 mm could toughen polystyrene significantly....

4. Synthesis of sub-micrometer core–shell rubber particles with 1,2-azobisisobutyronitrile as initiator and deformation mechanisms of modified polystyrene under various conditions
BACKGROUND: Sub-micrometer core-shell polybutadiene-graft-polystyrene (PB-g-PS) copolymers with various ratios of polybutadiene (PB) core to polystyrene (PS) shell were synthesized by emulsion grafting polymerization with 1,2- azobisisobutyronitrile (AIBN) as initiator. These graft copolymers were blended with PS to prepare PS/PB-g-PS with a rubber content of 20 wt%. The mechanica...
