Decher, G., Maclennan, J., Sohling, U., Reibel, J. (1992). Creation and structural comparison of ultrathin film assemblies -transferred freely suspended films and Langmuir-Blodgett-films of liquid-crystals. Thin Solid Films 210 504-7. [Pg.872]

The following paragraphs describe selected examples of Langmuir-Blodgett films, freely-suspended liquid crystal films, transferred freely-suspended films and layer-by-layer adsorbed films with respect to some of the desired properties described above. [Pg.446]

Comparison of Transferred Freely-Suspended Films and Langmuir-Blodgett Films of the Same Liquid Crystalline Amphiphile. [Pg.450]

Figure 2. Schematic of the transfer of freely-suspended liquid crystal films onto solid supports. (A) The freely-suspended film spans across an aperture of mm2 to cm2 size. (B) Withdrawing air from the inner compartment cause the film to bulge towards the substrate. Note that the drawing is not to scale, the thickness of the film is only a few nm and its actual distance from the substrate is less than a mm. (C) Further reduction of internal pressure brings the film into contact with the substrate. (D) After the transfer is complete the part of the film connecting the aperture and the substrate breaks and transferred FS-films of up to 1-2 cm2 are obtained. Figure 2.

Freely-Suspended and Transferred Freely-Suspended Liquid Crystal Films Candidates for Optically Homogenous Films... [Pg.449]

We have tried to stabilize freely-suspended films in two ways a) by transfer onto solid substrates and b) by using polymeric liquid crystals. [Pg.449]

The Langmuir Blodgett technique offers the unique advantage to cover holes in perforated substrates. It has been shown, that films of tethered polyisoprenes with photoreactive side groups can be cross linked on the water surface via irradiation [27]. These cross-linked films of 40 nm thickness can be transferred to grids and perforated substrates and can span holes of up to 300 jum in diameter. Since these freely suspended films are made out of a cross-linked polymer melt, they show rubber elastic behaviour. [Pg.298]
