Selectively grafting polymer from the interior and/or exterior surfaces of bioreducible and temperature-responsive nanocapsules
A novel strategy is reported for selectively grafting polymer brushes from the interior and/or exterior surfaces of bioreducible and temperature-responsive nanocapsules. Poly(N-isopropylacrylamide-copoly(ethylene glycol) methacrylate) (P(NIPAM-co-PEGMA)) nanocapsules with hydroxyl groups at the interior surface, exterior surface or both surfaces were first prepared via seeded prec...

Bioinspired design of nanostructured elastomers with crosslinked soft matrix grafting on the oriented rigid nanofibers to mimic mechanical properties of human skin
Human skin exhibits highly nonlinear elastic properties that are essential to its physiological functions. It is soft at low strain but stiffat high strain, thereby protecting internal organs and tissues from mechanical trauma. However, to date, the development of materials to mimic the unique mechanical properties of human skin is still a great challenge. Here wereporta...

Grafting of telechelic poly(lactic-co-glycolic acid) onto O2 Plasma Treated Polypropylene Flakes
In this work, we described a facile approach to preparing polypropylene (PP) surface functionalized with telechelic poly(lactic-co-glycolic acid) (HOPLGA-COOH). The PP flakes were first treated with oxygen plasma and then grafted with different molecular
weight PLGA (Mw ? 50, 100, and 300 K) in dry dichloromethane solution with the addition of phosphorus pentachloride (PCl...

Synthesis of an Amphiphilic Brush Copolymer by a Highly Efficient “Grafting onto” Approach via CO2 Chemistry
A novel and robust route for the synthesis of a new amphiphilic brush copolymer, poly(glycidyl methacrylate)-graft-polyethylene glycol (PGMA- g -PEG), with high grafting densities of 97%–98% through a “grafting onto” method via carbon dioxide chemistry is reported. PGMAg-PEG can self-assemble and form stable spherical core–shell micelles in aqueous solution. Besides, the obtained P...

High-efficiency grafting of halloysite nanotubes by using p-conjugated polyfluorenes via ‘‘click’’ chemistry
New hybrid halloysite nanotubes (HNTs) were
obtained by grafting conjugated polyfluorenes (PFs) onto
the surface via ‘‘click’’ chemistry. The hybrid material can
be dispersed in organic solvent such as dichloromethane,
and exhibits intense blue emission peaked at 448 nm. The
absorption and emission spectra of the HNTs show distinct
bathochromic shifts compared to PFs, which can be attributed
t...

Efficient grafting of hyperbranched polyglycerol from hydroxyl-functionalized multiwalled carbon nanotubes by surface-initiated anionic ring-opening polymerization
Biocompatible hyperbranched polyglycerol (HPG) has been covalently grafted from the surfaces of multiwalled carbon nanotubes (MWNTs) by the "grafting from" method based on in situ anionic ring-opening polymerization. The macroinitiator of hydroxyl-functionalized MWNTs (MWNT-OH) with hydroxyl density of 1.39 mmol per gram of nanotubes was prepared by one-pot nitrene chemistry in N-methyl-2-pyrrolid...

Facile functionalization of multilayer fullerenes (carbon nano-onions) by nitrene chemistry and “grafting from” strategy
Facile functionalization of multilayer fullerenes (carbon nano-onions, CNOs) was carried out by [2+ 1] cycloaddition of nitrenes. The products were further derivatized by using the "grafting from" strategy of in situ ring-opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Using one-step nitrene chemistry with high-energy reagents, such as azidoethanol and azidoethyl 2-br...

One-step synthesis of versatile amine- and vinyl-capped magnetic iron oxide nanoparticles for polymer grafting, dye adsorption and catalysis
Magnetic iron oxide nanoparticles (MIONs) bearing amine and vinyl groups are fabricated straightforwardly using vinyl-based tertiary amine molecules as both alkaline source and ligands based on the coprecipitation of iron ions in aqueous solution. The as-prepared MIONs present amphiphilic performance that can be well-dispersed both in aqueous solution and common organic solvents (e.g., ethanol, di...
