A thick sol–gel inorganic layer for optical planar waveguide applications

Comparative study on hydrophobic anti-reflective films from three kinds of methyl-modified silica sols

“…Up to now, there have been many reports on the preparing methods of sol-gel AR films and their application . AR films have been applied in fabricating cover glass for solar cells [1][2][3][4][5][6], glazings [7,8], windshields of automobiles [9], optical instruments [10][11][12][13][14] and so on. In the past research, although multi-layer AR film [25][26][27][28] and graded-index AR film [23,25,29] could be designed easily, their fabrication was difficult.…”

Synthetic clay nanocomposite‐based coatings prepared by UV‐cure photopolymerization

“…Finally, laponite films can be used in the manufacture of electrically conductive, antistatic, and protective coatings at low cost. 25 Not surprisingly, several researchers have been studying the effect of laponite in nanocomposites. For instance, Inan and coworkers 26 recently investigated the effect of laponite in nylon-6 nanocomposites, focusing on the mechanism of char formation and flame-retardation behavior.…”

Lithium iodate nanocrystals in Laponite matrixfor nonlinear optical applications

“…8 The interest of Laponite which is generally used to produce catalytic, antistatic and protective coating at very low cost, has been demonstrated in integrated optics. 9 The Laponite JS, provided by Rockwood Specialties Inc., is a synthetic trioctahedric hectoritic clay. Individual particles are disk-shaped crystals, 25 nm in diameter and 1 nm in width, with the chemical composition Na 0.7 10 The precursor solution is prepared at room temperature by dispersing 3 wt.…”

“…9 This structure presents interparticle spaces where lithium iodate solution is confined during the layer formation. The probability of nucleation is greatly reduced in small volumes 14 preventing crystallization during this stage.…”
