چکیده

Well-defined, ordered arrays of nanoscale depressions were obtained in linear-brush-type polystyrene-block-polycarbosilane (PS-b-PCS) diblock copolymer thin films by acetone vapor annealing and silica nanodot arrays were directly obtained from such thin films deposited on a titania substrate by one-step exposure to UV light as a result of transformation of the PCS units to silica, driven by the photocatalytic activity of titania concurrent with removal of the organic matrix.

Crosslinked Poly(styrene)-block-Poly(2-vinylpyridine) Thin Films as Swellable Templates for Mesostructured Silica and Titania

Traditional approaches to the formation of mesostructured inorganic films from block-copolymer and surfactant templates rely on simultaneous assembly of amphiphilic structure-directing agents and inorganic sol–gel precursor species into ordered hybrid structures. Variations in sample composition and processing conditions have afforded considerable control over the local (nanometer-scale) morpho...

Nanopatterning via Self-Assembly of a Lamellar-Forming Polystyrene-block-Poly(dimethylsiloxane) Diblock Copolymer on Topographical Substrates Fabricated by Nanoimprint Lithography

The self-assembly of a lamellar-forming polystyrene-block-poly(dimethylsiloxane) (PS-b-PDMS) diblock copolymer (DBCP) was studied herein for surface nanopatterning. The DBCP was synthesized by sequential living anionic polymerization of styrene and hexamethylcyclotrisiloxane (D₃). The number average molecular weight (Mn), polydispersity index (Mw/Mn) and PS volume fraction (φps) of the DBCP wer...

Deciphering the three-dimensional morphology of free-standing block copolymer thin films by transmission electron microscopy.

Block copolymer thin films with distinct morphologies are prepared by spin casting a nominally lamellar assay of poly(styrene-block-ethylene oxide) from a variety of solvents with and without salt doping. The 3-D morphologies of free-standing thin-film regions, which are obtained by casting directly onto holey substrates, are investigated in detail using various energy-filtering transmission el...

Lateral nanopatterns in thin diblock copolymer films induced by selective solvents.

Block copolymers have long been studied for their theories and applications especially in nanotechnology.1-5 They have periodic structures with 10-100 nm long microphase separated domains which can be controlled by the molecular weight and composition of the block copolymer. Regulating these two parameters, one can prepare thin films with different morphologies over large areas. The patterns fo...

The Effect of thickness parameter and Fluorine Dopant on Photocatalytic performance of TiO2 thin films

In this study, Pure and doped titania sols with Fluorine (F/Ti:0.06) dopant, were prepared by sol-gel method and Ammonium Fluoride(NH4F) as the precursor. They were deposited on glass substrates (soda lime) in a certain(optimum) nanometric thickness by the dip coating method. Coated samples were dried and calcined under the specific rate. Phase composition and optical properties of coatings wer...
