Synthesis and Characterization of Novel Polyimide/TiO2 Nanocomposite System for the Application of Organic Electronics

Ahn T., Yu Y.I., Hong S.K., Yi M-Y, Korea Research Institute of Chemical Technology, KR

Organic/inorganic nanocomposites have become an effective source of advanced materials as they usually exhibit unique properties that traditional composites and conventional materials do not have. They combine the advantages of the inorganic material (rigidity, high [...]

Polyvinyl Alcohol (PVA)/Layered Silicate Nanocomposite Approaches for Organic Passivation Layers in Organic Thin Film Transistors

Ahn T., Suk H.J., Yi M-Y, Korea Reserch Institute of Chemical Technology, KR

Organic thin-film transistors (OTFTs) have been demonstrated as promising candidates for flexible displays, smart cards (badges), and gas sensors. These applications with organic electronics offer many advantages, such as light weight, low cost processing, and [...]

Synthesis and Thin-Film Transistor Performance of Fluorene-based Copolymers Containing Thiophene Moieties Having Different Position of Alkyl Side Chain

Kong H.Y., Lim E., Jung Y.K., Park M.-J., Ahn T., Yi M.H., Kang I.-N., Shim H.-K., KAIST, KR

We have synthesized fluorene-based copolymers (PF-HT-TT-TH and PF-TH-TT-HT) containing thiophene moieties having different position of alkyl side chain via the palladium-catalyzed Suzuki coupling reaction. The number-average molecular weight (Mn)s of PF-HT-TT-TH and PF-TH-TT-HT were respectively [...]
