Oxygen enrichment by a Langmuir-Blodgett film of poly(n-dodecylacrylamide) on porous aluminum oxide

Le facteur de separation de la membrane composite preparee pour le systeme O 2 /N 2 atteint 2 entre 10 et 70 o C, avec une vitesse de permeation de l'oxygene variant entre 10 −4 et 10 −3 cm 3 /cm 2 s. cm Hg

Preparation and properties of poly-(p-phenylenevinylene) Langmuir-Blodgett film

An LB film of poly( p-phenylenevinylene) (PPV) was successfully prepared by heat treatment of the Langmuir-Blodgett (LB) film of an amphiphilic poly( p-xylylene sulfonium salt). The electrical conductivities of the SO 3-doped PPV LB film were 0.5 and 1 × 10 −5 S cm −1 in the lateral and normal directions, respectively. The PPV LB film was electrochemically doped and dedoped at E = +0.56 V and E = +0.16 V vs. Ag/AgCl, respectively.

Preparation of a conducting ultrathin multilayer film of poly(p-phenylene vinylene) using a Langmuir–Blodgett technique

An electrically conducting Langmuir–Blodgett (LB) film of poly(p-phenylene vinylene)(4) with no alkyl spacer chains has been prepared for the first time by the deposition of a LB film of poly(sulphonium salt)(2b)(X = C9H17CO2) on an appropriate plate, followed by thermal conversion.

Electron-beam resists from Langmuir-Blodgett films of poly(styrene/maleic anhydride) derivatives

A range of styrene/maleic anhydride polymer derivatives and some related polymers have been synthesized and their performance as electron-beam resists assessed, initially as spin-coated films and then as Langmuir-Blodgett (LB) films on silicon. The effects of molecular structure, molecular weight and packing have been investigated in designing materials for optimum sensitivity and resolution. The most promising materials contain vinyl or ethynyl crosslinking groups and are negative resists, resolution ≈ 0.25 μm and gel dose in the range 1–40 μC cm −2. Exposed and developed LB films only 50 layers (≈ 50 nm) thick have good plasma etch resistance, allowing the processing of tri-level resist structures (polyimide/Al/LB film) with little loss of resolution. This indicates that LB films based on poly(styrene/maleic anhydride) have the potential for the fabrication of submicrometre electronic devices.
