Poly-4-vinylpyridine electrets

Non-volatile organic transistor memory devices using the poly(4-vinylpyridine)-based supramolecular electrets.

Supramolecular electrets consisting of poly(4-vinylpyridine) (P4VP) and conjugated molecules of phenol, 2-naphthol and 2-hydroxyanthracene were investigated for non-volatile transistor memory applications. The memory windows of these supramolecular electret devices were significantly enhanced upon increasing the π-conjugation size of the molecule. A high ON/OFF current ratio of more than 10(7) ...

Polyoxometalate-modulated self-assembly of polystyrene-block-poly(4-vinylpyridine).

Polyoxometalates can serve as active components to induce and modulate the micellization behavior of polystyrene-block-poly(4-vinylpyridine).

Poly(vinylpyridine oxides) in pneumoconiosis research.

Poly(vinylpyridine oxides) in pneumo-coniosis research. Schlipkoter and Brockhaus of the Institut fur Lufthygiene Dusseldorf found that poly(2-vinylpyridine 1-oxide) can inhibit the fibrosis normally produced by quartz dust in the lungs or other tissues of animals. Later research in Germany and elsewhere has confirmed the earlier observations. The polymer is active when the quartz is administer...

Origin of the Difference in Order-Disorder Transition Temperature between Polystyrene-block-poly(2-vinylpyridine) and Polystyrene-block-poly(4-vinylpyridine) Copolymers

Three polystyrene-block-poly(2-vinylpyridine) (S2VP diblock) and three polystyrene-block-poly(4-vinylpyridine) (S4VP diblock) copolymers with varying molecular weights and block compositions were synthesized via anionic polymerization, and their order-disorder transition temperatures (TODTs) were determined using oscillatory shear rheometry and small-angle X-ray scattering (SAXS). It has been f...
