Abstract Recent advances in the enrichment of semiconducting single-walled carbon nanotubes (s-SWCNTs), particularly via conjugated polymers extraction, allow for their wide applications with unique performances, especially for transistors and sensors. Both the low-cost enrichment and convenient device fabrication of s-SWCNTs have become high-priority and challenging tasks. In this study, we demonstrate that a dopamine functionalized thiophene-fluorene copolymer has the capability of selectively...

Abstract Zwitterionic monomer methyacryloxyethyl sulfobetaine (MAES) copolymerized with hydroxyethyl methacrylate (HEMA) forming random copolymer with some block characteristics in a controlled manner. The polyzwitterionic copolymer P(MAESx-ran-HEMAy) (PMxHy, where x and y were the degrees of polymerization of MAES and HEMA, respectively), which bearing hydroxyl groups that served as both reducing and capping reagent for in situ AgNPs synthesis without exogenous additions. The in situ formed uni...

Abstract Various phosphorus flame retardants (FR) have been grafted on lignin-rich miscanthus fibers and lignin-poor flax fibers according to two methods, phosphonic acids condensation in mild conditions and radiation grafting. Phosphorus content and its location on fibers were evaluated. Even if phosphorus FR diffused into the fibers bulk in all cases, chemical modification based on phosphonic acids condensation with hydroxyls of miscanthus fibers appears more suitable for high lignin content f...

Abstract The present work describes how the thermal response of some thermosensitive poly(N-isopropylacrylamide)-poly(ethylene glycol)-poly(N-isopropylacrylamide) (PNIPAM-PEG-PNIPAM) triblock copolymers of different compositions, in aqueous solution, estimated by the cloud point (CP) method, can be controlled by factors like polymer concentration (0.05–5 wt%) and composition (PNIPAM and PEG blocks length, overall polymer hydrophilicity), as well as by the nature and concentration (0.1–0.4 M) of ...

Abstract This study presents a new procedure for the preconcentration of trace levels of silver (I) in an aqueous matrix, through a minicolumn packed with a dithiooxamide-immobilised polysiloxane. The functionalized adsorbent has been synthesized by a sol-gel route and characterized by different physicochemical methods: an elemental analysis was made on a Perkin-Elmer automated analyzer, IR spectra were obtained with a Thermo Nicolet 6700 spectrometer, and thermograms, with a Mettler Toledo TGA/...

Abstract Light emission has been introduced onto poly(ethylene-co-acrylic acid) (PEAA) surfaces by covalently grafting two different fluorescent moieties. The facile surface modification method presented allows commercial polymers to be used for light emitting and sensor applications. Two fluorescent compounds, 4′-(octyloxy)-4-biphenyl carboxylic acid (OBC) and 2,7-bis (bromomethyl)-9,9-dihexyl-9H-fluorene (BMDF), were covalently grafted to the surface of PEAA films. Conversion of the carboxylic...

Abstract The use of functional polymers for the sorption of metallic species in water was widely practiced in treatment processes. Such sorbents offered the possibility to remove a large range of metals because of the variety of possible functional groups on polymeric backbones. In particular, acidic groups (carboxylic, phosphonic or sulfonic groups) proved to be of great interest for the sorption of different cations. Sorption efficiency and selectivity through complexation or ion exchange inte...

Abstract The main objective of the work was to elaborate a methodology of manufacturing tubular guide with an internal scaffold of polysaccharide hydrogel towards potential application for supporting peripheral nerve regeneration. Carboxymethylchitosan (CMSC), a derivative of chitosan and a prospective material in the medical field, was examined with respect to degradation and crosslinking processes and eventually converted into a hydrogel through radiation-induced crosslinking. Physical-chemica...

Abstract The piezoresistive behaviour of SEBS-CNTs nanocomposites was investigated to evaluate their. potential applications as strain sensors. Composites containing from 3%wt. to 7%wt. of CNTs were processed by injection moulding in order to evaluate the percolation threshold. The piezoresistive response under flexural strain of nanocomposites with a CNTs content above the percolation threshold was then studied. The nanocomposites showing the most promising performance were tested under cyclic ...

Abstract The conventional method of dendrimer synthesis, especially poly(propyleneimine) dendrimer (PPI) involves complicated reaction workup and tedious separation strategies. Since it has greater number of nitrogen atom in the structure, it has numerable applications in different fields. But these dendrimers cannot be recycled for subsequent applications. In order to overcome these issues, for the first time, divergent synthesis of poly(propyleneimine) dendrimer G3 on silica coated magnetite h...
