Real-Time Grazing Incidence X-ray Diffraction Studies of Polymerizing n-Octadecyltrimethoxysilane Langmuir Monolayers at the Air/Water Interface

Grazing Incidence Synchrotron X-ray Diffraction of Polymerizing Langmuir Monolayers

“…Previously, we have shown that standard Langmuir trough monolayer techniques coupled with synchrotron GIXD have sufficient time-resolution to follow structural changes induced by a polymerization reaction. 30 We have also reported that a nucleation-type growth precedes the 2D gelation of the material. In this paper, synchrotron GIXD is utilized to further investigate the structural transformations occurring in this reacting monolayer system.…”

“…30 GIXD Instrumentation. The X-ray beam from the undulator was monochromatized by a double silicon crystal monochromator tuned to provide X-ray energy of 10 or 11 keV (λ ) 1.13 or 1.24 Å, respectively).…”

Influence of temperature and alkyl chain length on phase behavior in Langmuir monolayers of some oxyethylenated nonionic surfactants

“…From the applied aspects, Langmuir monolayers are excellent model systems for membrane biophysics, since a biological membrane can be considered as two weakly coupled monolayers. Besides, they are used to study chemical [2] and biochemical reactions [3,4] in two dimensions and to fabricate LangmuirBlodgett films by layer-by-layer transfer from the water surface onto a solid substrate for specific applications in optical and electronic devices, as well as for the study of lubrication, friction, and wetting [5,6]. Although enormous complexity arises in studying the phase behavior of amphiphilic systems at the air-water interface because of a variety of intermolecular interactions, including those with subphase water, Langmuir monolayers provide a unique opportunity to gain insights into the physical properties of two-dimensionally organized molecules in a variety of phases.…”

Surface modified ormosil nanoparticles

“…Numerous research groups have studied alkylsilanes and alkoxysilanes as components in hybrid materials for surface modifications [3][4][5][6][7]. Various other alkylalkoxysilanes have been used in the synthesis of alkylpoly(siloxanes) [8][9][10][11][12].…”
