Which would you opt for between saying polyphenylene vinylene or PPV?
There are many references about the corrosion resistance of electroactive polymers such as polyaniline (PANi) (61-72) poly-n-ethylaniline, (73) polyphenylene oxide, (74) and poly (2,5-bis (N-methy1-N-hexylamine) -p-phenylene vinylene (75) as pigment in paint or coatings.
26 PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES, makes use of MPS-PPV, a fluorescent polymer--a giant molecular chain of repeating units--belonging to the polyphenylene vinylene family.
After the conducting polymer layer is dried, the emissive polymer is deposited in a pattern and can include any of a wide range of suitable polymers, including Polyphenylene Vinylene (known as PPV), polyfluorenes, or others.
The conductive polymers include polyacetylene, polypyrrole, polythiophene, poly(3-alkylthiophene), polyphenylene sulfide, polyphenylene vinylene, polythienylene vinylene, polyphenylene, polyisothianaphthalene, polyazulene, polyfurane, and polyaniline.
Colvin, a chemist at the University of California, Berkeley, and her colleagues report making a new kind of variable-color LED by blending cadmiumselenide nanocrystals with the semiconducting polymer p-paraphenylene vinylene.
The incorporation of vinylene linkages in the polymer backbone facilitates to planarize the chain structure by overcoming torsional interactions between the rings and thus extending the effective conjugation length.
The conducting monomer can be aniline, pyrrole, thiophene, acetylene, paraphenylene, or phenylene vinylene, and the solvent can be hydrochloric, sulfuric, hydrogen nitrate, phosphoric, or acetic acid.
