Improved mechanical and antibacterial properties of silver-graphene oxide hybrid/polylactid acid composites by in-situ polymerization
关键字：Silver,Graphene oxide,Nanocomposite,Flexural properties,Antibacterial properties
Mechanical and antibacterial properties of polylactid acid have to be improved for advanced applications of medical instruments, artificial tissues and active packaging, etc. In this work, antibacterial polylactid acid nanocomposites are developed by using silver-graphene oxide hybrid (Ag@GO) as filler via in-situ polymerization and direct mechanical blending method, respectively. The effects of...

High performance poly(N-aryleneindole ether) containing pyridine units as a novel acid response fluorescent detector
关键字：poly(N-aryleneindole ether); pyridine; sensor; luminescence
A novel high-performance polyindole containing a pyridine ring (P1)was successfully prepared by the catalyst-free nucleophilic substitution polycondensation of 4-hydroxyindole with 2,6-difluoropyridine via a C?N and C?O coupling reaction process. This semirigid polyindole P1 exhibits good thermal stability, and it can be dissolved well in common organic solvents. Fluorescent spectral studies ind...

In situ generation of bioreducible and acid labile nanogels/microgels simply via adding water into the polymerization system.
关键字：insitu generation, nanogel, stimuli-responsive
A novel and versatile method for one-pot and in situ generation of bioreducible and acid labile nanogels/microgels simply via adding water into the polymerization system is reported. The produced polymers in the polymerization system become temperature-sensitive and less soluble after adding water, and hence they collapse together, forming nanoparticles. Subsequently, the disulfid...

Br?nsted Guanidine Acid-Base Ionic Liquids Novel Reaction Media for the Palladium-Catalyzed Heck Reaction
关键字：Ionic liquids, Heck reaction, guanidine
Br?nsted acid?base ionic liquids (GILs) based on guanidine and acetic acid are efficient reaction media for palladium-catalyzed Heck reactions. They offer the advantages of high activity and reusability. GIL2 plays multiple roles in the reaction: it could act as solvent, as a strong base to facilitate a-hydride elimination, and as a ligand to stabilize activated Pd species.

Determination of molecular weight of polyethylene glycol using size-exclusion chromatography with multi-angle laser lightscattering and acid–base titration
关键字：polyethylene glycol
Size-exclusion chromatography with multi-angle laser light scattering (SEC-MALLS) and
acid–base titration were used to determine the molecular weight of a polyethylene glycol
with low molecular weight. All potential uncertainty factors for each measurement were
evaluated using cause-effect diagrams. Weight analysis was applied to harmonize the two
different measurement results. It was fo...
