Influence from the sulfonate group (RSO(3)(-)) on the conversion process and emission efficiency of poly(p-phenylene vinylene)
(ELSEVIER SCIENCE BV, 2010)
The discovery of an alternative route to convert poly(xylyliden tetrahydrothiophenium chloride) (PTHT) into poly(p-phenylene vinylene) (PPV) using dodecylbenzenesulfonate (DBS) has allowed the formation of ultrathin films ...
Phase Diagrams of Blends of Poly(phenylene ether), Polystyrene, and Diglycidyl Ether of Bisphenol A: Influence of the Molar Mass of Poly(phenylene ether)
(John Wiley & Sons Inc, 2006-05-06)
Phase diagrams of ternary blends of poly(phenylene ether) (PPE, M n = 1.2 and 12 kg mol-1), polystyrene (PS, Mn = 22.5 kg mol-1), and diglycidyl ether of bisphenol A (DGEBA) were experimentally obtained in an extended range ...
Photoconductivity excitation spectrum for stretch-oriented PPV
(Elsevier B.V., 2005-09-22)
We have obtained the photoconductivity (PC) excitation spectrum for a stretch-oriented poly(paraphenylene vinylene) film over a wide spectral range (up to 5 eV). The measurements were performed in the surface cell configuration ...
Photoconductivity excitation spectrum for stretch-oriented PPV
(Elsevier B.V., 2005-09-22)
We have obtained the photoconductivity (PC) excitation spectrum for a stretch-oriented poly(paraphenylene vinylene) film over a wide spectral range (up to 5 eV). The measurements were performed in the surface cell configuration ...
Polymeric coatings for photostability enhancement of poly(p-phenylene vinylene) derivative films
(John Wiley and SonsBognor Regis, 2010-05)
Poly(p-phenylene vinylene) (PPV) derivatives are an important class of conjugated polymers, known for their applications as electroluminescent materials for light-emitting devices and sensors. These derivatives are highly ...
Moisture and temperature influence on mechanical behavior of PPS/buckypapers carbon fiber laminates
(2017-07-01)
In this work, multiwall carbon nanotubes (MWCNT) were dispersed in water with the assistance of water based surfactant and then sonicated in order to obtain a very well dispersed solution. The suspension was filtrate under ...
Effect of a polymeric protective coating on optical and electrical properties of poly (p-phenylene vinylene) derivatives
(HindawiNew York, 2013)
The resistance to photodegradation of poly [(2-methoxy-5-n-hexyloxy)-p-phenylene vinylene] (OC1OC6-PPV) films was significantly enhanced by the use of poly(vinyl alcohol) 99% hydrolyzed as protective coating. The deposition ...
Atomistic molecular dynamics study of interface formation: Al on poly(p-phenylene vinylene)
(AMER PHYSICAL SOC, 2008)
We model interface formation by metal deposition on the conjugated polymer poly-para-phenylene vinylene, studying direct aluminum and layered aluminum-calcium structures Al/PPV and Al/Ca/PPV. To do that we use classical ...
Synthesis and characterization of semiconductor polymers having different phenylene-vinylene conjugation lengths
(SPRINGER, 2008)
We have synthesized phenylene-vinylene (PV) polymers containing segments with different conjugation lengths interspaced by random distributed aliphatic segments. Infrared (IR) and ultraviolet-visible (UV-vis) spectroscopies, ...
