Surface roughness of glass is desired to be arbitrary controlled because it affects a variety of properties such as tactile impression, optical properties, and contact chargeability. While the surface modification is currently achieved by wet etching of the glasses with hydrofluoric acid, there is still room for improvement because the wet etching cannot be simultaneously applied during flat glass production. We recently developed novel etching scheme, which uses gaseous hydrogen fluoride (HF) under high temperature. Because the flat glasses are kept hot during the production, our procedure can be introduced to the flat glass production process. Here, we demonstrate that surface nano-roughness (1-20 nm of arithmetic mean roughness) of silicate glasses can be rapidly and reproducibly controlled by our method with changing the reaction temperature. It was found that the reaction with gaseous HF heterogeneously left metal fluorides on the glasses and that the fluorides partially masked the further reaction. High reaction temperature led the fluoride particles larger, resulting in rougher surface after removing the fluoride layer. It took only a few seconds for this reaction.

“…Controlling surface morphology such as roughness has attracted particular attention in bulk materials in terms of energy saving and environmentally friendly applications. Surface controlled materials are widely utilized as antireflection surfaces [ 1 , 2 , 3 , 4 ], light harvesting films [ 5 , 6 , 7 ], superhydrophobic surfaces [ 8 , 9 , 10 , 11 , 12 ], etc. In parallel, the surface control of an individual particle composing bulk material on the nanoscale is also an important issue considering the fabrication and engineering for versatile applications, for example, heterogeneous catalysts [ 13 , 14 ], biological cellular uptake [ 15 , 16 ], and so on.…”

The surface morphology of Mg-Al-layered double hydroxide (LDH) was successfully controlled by reconstruction during systematic phase transformation from calcined LDH, which is referred to as layered double oxide (LDO). The LDH reconstructed its original phase by the hydration of LDO with expanded basal spacing when reacted with water, including carbonate or methyl orange molecules. During the reaction, the degree of crystal growth along the ab-plane and stacking along the c-axis was significantly influenced by the molecular size and the reaction conditions. The lower concentration of carbonate gave smaller particles on the surface of larger LDO (2000 nm), while the higher concentration induced a sand-rose structure. The reconstruction of smaller-sized LDH (350 nm) did not depend on the concentration of carbonate due to effective adsorption, and it gave a sand-rose structure and exfoliated the LDH layers. The higher the concentration of methyl orange and the longer the reaction time applied, the rougher the surface was obtained with a certain threshold point of the methyl orange concentration. The surface roughness generally increased with the loading mount of methyl orange. However, the degree of the surface roughness even increased after the methyl orange loading reached equilibrium. The result suggested that the surface roughening was mediated by not only the incorporation of guest molecules into the LDH but also a crystal arrangement after a sufficient amount of methyl orange was accommodated.
