Graphene/star polymer nanocoating
A kind of novel nanocoating based on star polymers and graphene was developed. The hydroxyl func-tionalized star polymers were synthesized by Activators Regenerated by Electron Transfer Atom TransferRadical Polymerization (ARGET ATRP) using core-first approach. The branching behavior, copolymercomposition and glass transition temperature was characterized clearly. Graphene/star polymer coatingshow...

CO2-Responsive polymer materials
CO2-Responsive polymer materials have received enormous attention in recent years, since CO2 as a new trigger has many advantages such as abundant availability, low cost, energy-saving, environment-friendly, non-toxic, good reversibility as well as great biocompatibility. In this review, we first discuss the virtues of CO2-responsiveness by comparing with traditional stimuli-sensitive materials ...

[Small] Patterned Polymer Carpets
For the development of polymer carpets as active devices for micro- and nanotechnology, a control of the polymer carpet morphology and especially control of the stimulus responsive polymer brush is needed. Here, we report on the fi rst example for the fabrication of patterned polymer carpets. On a two-dimensional framework of fully crosslinked and chemically patterned nanosheets, polymer brushes...

[Small] Polymer carpets
The fabrication of defined polymer objects of reduced dimensions such as polymer-coated nanoparticles (zero-dimensional (0D)), cylindrical brushes (1D), and polymermembranes (2D), is currently the subject of intense research. In particular, ultrathin polymer membranes with high aspect ratios are being discussed as novel materials for miniaturized sensors because they would provide extraordinary ...

The novel comb-type biodegradable graft copolymers based on e-caprolactone and L-lactide were synthesized. Firstly, 2-oxepane-1,5-dione (OPD) was synthesized by the Baeyer–Villiger oxidation of 1,4-cyclohexanedione, and wassubsequently copolymerized with e-caprolactone (CL) to produce poly(2-oxepane-1,5-dione-co-e-caprolactone) (POCL) catalyzed by stannous(II) 2-ethylhexanoate in toluene. Th...

The synthesis, characterization, and degradability of the novel aliphatic polyester bearing pendant N-isopropylamide functional group are reported for the first time. 2-(N-Isopropyl-2-carbamoylethyl) cyclohexanone (CCH) was first synthesized by the Michael reaction of N-isopropylacrylamide with cyclohexanone and was subsequently converted into 6-(N-isopropyl-2-carbamoylethyl)-3-caprolactone (CCL) ...

The purpose of this research was to synthesize and characterize a novel class of four-arm, star-shape biodegradable polymers having double-bond functionality as a precursor for free-radical polymerization, with unsaturated monomers or macromers or photocrosslinking for network formation. The synthesis involved two basic steps. First, hydroxyl-functionalized four-arm poly(_-caprolactone) s (PPCL-OH...

Poly(ethylene glycol)-block-poly(butyl acrylate) synthesized by radical polymerization in a one-step procedure were characterized by gel permeation chromatography, infrared, 1H-NMR spectroscopy, and differential scanning calorimetry (DSC). The crystalline property, emulsifying property, and phase transfer catalytic effect in the Williamson reaction were studied. It was found that the crystallinity...

Prepolymers of poly(ethylene oxide) (Pre-PEO) were synthesized by reacting azoisobutyronitrile (AIBN) with poly(ethylene glycol) (PEG), and their structures were characterized by IR and UV. The molecular weight of pre-PEO was related to the feed ratio and reaction time. These prepolymers can be used to prepare block copolymers—poly(ethylene oxide) -block-poly(butyl acrylate) (PEO-b-PBA) by r...
