Abstract:
A facial method of fabricating methyl-modified silica nanobowl using a polystyrene template with tetraethoxysilane (TEOS) and methyltriethoxysilane (MTES) as co-precursors was reported. The morphology of the nanobowl was determined by the mole ratio of TEOS and MTES, and the size and shell thickness of the PS@SiO2. And the 2D ordered nanostructure has also been developed with a nanobowl opening perpendicular to the glass substrate surface by the Langmuir-Blodgett technique. These 2D ordered nanobowl structures present an adjustable antireflection property. The single-side nanobowl coating has a transmission improvement of 4.5% compared to the uncoated glass at a wavelength of 540 nm. Furthermore, the nanobowl structures have good hydrophobicity with a contact angle up to 130° without any additional treatment. The quantitative deformation behavior of the methyl-modified silica nanobowl was also discussed.
