Selective sequential infiltration synthesis of ZnO in the liquid crystalline phase of silicon-containing rod-coil block copolymers

Abstract

The highly selective and uniform infiltration of ZnO in PMPCS liquid crystalline microdomains of rod-coil DM diblock copolymers and DSM triblock terpolymers highlights their potential in 3D hybrid nanofabrication.

Monolithic light concentration by core-shell TiO2 nanostructures templated by monodisperse polymer colloidal monolayers

“…This process is related to other chemical infiltration techniques described elsewhere. [24][25][26] Further, we use finite difference time domain (FDTD) simulations to study the optical properties of these coreshell surfaces. We use these simulations to design favorable optical resonances in a monolithic, light-concentrating structure that shows enhanced absorption in a simulated ultra-thin, GaAs-based PCA device.…”

Solvent-assisted self-assembly of block copolymer thin films

“…210 Non-native multilayered ZnO structures were fabricated by templated synthesis using solvent vapor annealing as a rapid ordering method of BCP templates. 211,212 Combinatorial exploration of SVA Finding suitable SVA conditions and engineering the optimal processing pathway remain a challenge and require systematic studies. Combinatorial experiments offer a great promise in this regard and have been applied to elucidate SVA phenomena, e.g., screening for optimal solvent-mixture composition in gradient-composition solvent vapor annealing 178 and in recent autonomous investigations of film thickness effects.…”

Conductive Polyaniline–Indium Oxide Composite Films Prepared by Sequential Infiltration Synthesis for Electrochemical Energy Storage

“…Sequential infiltration synthesis (SIS) is one of the subcategories of atomic layer deposition (ALD), and it has recently emerged as a promising way to prepare organic–inorganic composite films with excellent control over their morphologies. − The following are the major SIS growth mechanisms: (1) precursor infiltration into the polymer matrix; (2) reversible/irreversible reaction of the precursor with specific functional groups of the polymer; and (3) chemical reactions between precursors and coreactant precursors within the polymer matrix. − Various compositional and structural factors of the composite films, such as the ratio of organic-to-inorganic components and the distribution of the chemical composition, can be controlled by varying the SIS conditions, such as the growth temperature, precursor exposure time, and precursor purge time . Therefore, SIS is expected to be useful for preparing CP-MO composites with the content and distribution of MO carefully controlled.…”
