Formation of Asymmetric Films, as a Membrane Precursors, Using Langmuir and Langmuir-Blodgett Techniques

Langmuir-Blodgett films of polyethylene

Langmuir-Blodgett Films of Supported Polyester Dendrimers

Amphiphiles with a dendritic structure are attractive materials as they combine the features of dendrimers with the self-assembling properties and interfacial behavior of water-air affinities. We have synthesized three generations of polyester dendrimers and studied their interfacial properties on the Langmuir films. The behavior obtained was, as a rule, the lowest generation dendrimers behavin...

Ferroelectric nanomesa formation from polymer Langmuir-Blodgett films

Gas sensing using Langmuir - Blodgett films of a ruthenium porphyrin

We report on the Langmuir-Blodgett film formation and properties of a ruthenium porphyrin complex. Multilayer films may be transferred onto a variety of substrates. Reproducible deposition is indicated by both optical and electrical measurements. Ellipsometry reveals the thickness per layer to be 1.65 k 0.05 nm. A marked increase in the in-plane electrical conductivity of these layers is found ...

Stable ordering in Langmuir-Blodgett films.

Defects in the layering of Langmuir-Blodgett (LB) films can be eliminated by depositing from the appropriate monolayer phase at the air-water interface. LB films deposited from the hexagonal phase of cadmium arachidate (CdA2) at pH 7 spontaneously transform into the bulk soap structure, a centrosymmetric bilayer with an orthorhombic herringbone packing. A large wavelength folding mechanism acce...
