Abstract Surface molecularly imprinted cellulose‐synthetic hybrid particles are prepared via atom transfer radical polymerization (ATRP). The two‐step process involves the immobilization of α‐bromoisobutyryl bromide in pristine microcrystalline cellulose, to generate ATRP macroinitiator particles, and then creation a crosslinked‐imprinted shell surface considering 4‐vinylpyridine (4VP) ethylene...

Chitin is a representative biomass resource comparable to cellulose. Although considerable efforts have been devoted to extend novel applications to chitin, lack of solubility in water and common organic solvents causes difficulties in improving its processability and functionality. Ionic liquids have paid much attention as solvents for polysaccharides. However, little has been reported regardi...

We report the first use of a block terpolymer for the synthesis of three-component nanocomposites. Here, the use of three chemically distinct polymer blocks enabled control over each of the three final components: partially graphitic carbon, crystalline transition metal oxide, and porosity. Tuning of the individual block lengths and block fractions resulted in control over the three components....

Abstract This paper aimed to produce a bio-based filament, suitable for 3D printing (fused deposition modeling), made of surface modified cellulose fiber and high density polyethylene. The fibers (CF) were first transformed into CF-based macroinitiator through an esterification reaction with the 2-bromoisobutyric acid. We finally studied ability this initiate single electron transfer-living rad...

Shell-sheddable nanoparticles, composed of amphiphilic blockpolymers, have emerged as an attractive vehicle for the site-specific delivery therapeutic agents. In this study, pH-responsive sheddable copolymers bearing orthoester linker were synthesized via ring-opening polymerization between γ-benzyl-L-glutamate N-carboxyanhydride and orthoester-bearing poly (ethylene glycol) macroinitiator (PEG...

Asymmetric and semi-symmetric amphiphilic diblock copolymers polystyrene-block-poly (dimethylaminoethyl methacrylate) (PS-b-PDMAEMA) with the same PS block length of 62 repeat units and quite short (3 repeat units) or equivalent (47 repeat units) length of PDMAEMA have been prepared simply by varying the ratio of the bromine-terminated macroinitiator polystyrene (PS-Br) to DMAEMA using atom tra...

Convenient methods for the rapid, parallel synthesis of diversely functionalized nanoparticles will enable discovery of novel formulations for drug delivery, biological imaging, and supported catalysis. In this report, we demonstrate parallel synthesis of brush-arm star polymer (BASP) nanoparticles by the "brush-first" method. In this method, a norbornene-terminated poly(ethylene glycol) (PEG) ...

BACKGROUND: Self-assembling amphiphilic block copolymers with incorporated, biologically relevant functionalities have received limited attention, partly due to the fact that biomolecules are not robust enough to synthetic manipulation, do not lend themselves readily to systematic studies due to their complexity and leach rather quickly from a vesicle or membrane when physically incorporated. S...

Three types of ethylene oxide-based and carbonate-containing copolymers were prepared through copolymerization oxide (EO) with CO2 under metal-free conditions in the presence triethylborane (TEB), using onium salts (OS) as initiator. Hydrophobic poly[(ethylene carbonate)x-co-(ethylene oxide)y] (PECEO) samples carbonate contents above 90% (x ? y) first a pressure 10–30 bar ratio [TEB] to [OS] 1–...
