Plasma-polymerized multistacked bipolar gate dielectric for organic thin-film transistors

A 10-layer stack of bipolar gate dielectric was formed by sequential layer-by-layer deposition using pulsed radio frequency (RF) plasma polymerization of allylamine and vinyl acetic acid monomers. Due to polar groups localized at the interfaces between each consecutive layer by alternating amine (–NH2) and carboxylic acid (–COOH) functional groups, a 60 nm thick multilayer structure demonstrate...

Adhesion Properties of Self-Polymerized Dopamine Thin Film

We report an experimental study of the adhesion properties of polydopamine thin films and their bonding behavior on polymer, glass and metal surfaces. Dopamine is able to adsorb onto all surfaces and self-polymerize into a thin hydrophilic film. Dynamic contact angle measurements revealed a large contact angle hysteresis between advancing and receding angles and a possible hydration layer when ...

Plasma Polymerized Thin Films Materials: Synthesis, Characterization, and Application Tests

Organic–inorganic hybrid co-polymer thin films were deposited on silicon(100) substrates under the several ratio of TEOS (tetraethoxysilane) against cyclohexene by plasma enhanced chemical vapour deposition (PECVD) method. Toluene and TEOS were utilized as organic and inorganic precursors each, and hydrogen and argon were also used as a bubbler and carrier gases, respectively. In order to compa...

Amperometric biosensor based on glucose dehydrogenase and plasma-polymerized thin films.

A novel design is described for an amperometric biosensor based on NAD(P)-dependent glucose dehydrogenase (GDH) combined with a plasma-polymerized thin film (PPF). The GDH is sandwiched between several nanometer thick acetonitrile PPFs on a sputtered gold electrode (PPF/GDH/PPF/Au). The lower PPF layer plays the role as an interface between enzyme and electrode because it is extremely thin, adh...
