Stabilization and functionalization of single-walled carbon nanotubes with polyvinylpyrrolidone copolymers for applications in aqueous media 下载免费PDF全文

In spite of their useful electronic and mechanical properties, the utility of single-walled carbon nanotubes (SWNT) is limited by their inherent insolubility in aqueous environments and the difficulty in functionalizing the material while retaining opto-electric properties. In this article, the synthesis of polyvinylpyrrolidone (PVP) copolymers for wrapping SWNTs is described. Studies include the effect of polymer composition and charge on SWNT stability in aqueous solution and the variation of the stability of wrapped SWNTs during high-dilution conditions using dialysis studies. Finally, the PVP-copolymer strategy is used to create polymer wrappers with functional handles for the incorporation of useful chemical functionality. © 2014 Wiley Periodicals, Inc. J. Polym.

A preliminary X-ray photoelectron spectroscopic (XPS) investigation on poly[4,4′-isopropylidenebis(1,4-phenyleneoxyethylene) diacrylate] samples obtained by photocuring on several substrates in the presence of a fluorine containing acrylic monomer is reported. Quantitative calculations based on F1s/C1s area ratios and C1s peak fitting show a noticeable fluorine surface enrichment that ranges, depending on the substrate, from 17 wt.-% to 59 wt.-% of fluorine containing moiety. The calculations also reveal the presence of a concentration gradient at the surface. 相似文献

The discovery of the photochromic characteristics of engineered green fluorescent proteins (GFPs) allows new proteomics and biomolecular electronic applications. In particular, photoreversibility among two distinct optical states can lead to the realization of a bio-optical high density storage memory. Here we review our recent work on an optically bistable GFP and we report the recent developments of self-assembly methods for spatial immobilization of proteins into well-definite 2D patterns. 相似文献

Coatings obtained through photopolymerisation of vinylethers, propenyl ethers and epoxy resins are described. The influence of alcohols and of comonomers bearing OH groups on the cationic mechanism of the curing process is discussed. The final properties of the coatings are evaluated and correlated to the structures of the additives. 相似文献

Modern integrated circuits require insulating materials with a dielectric constant as low as possible in order to obtain device speed improvements through lower RC delay. We have investigated the electrical and structural properties of PTFE thin films obtained from Algoflon®-PTFE nanoemulsions, via spin coating deposition, followed by sintering. Films as thin as 160 nm with dielectric strength better than 4 MV/cm have been obtained. 相似文献
