A novel fabrication method of uniform porous structures on the glass surface is proposed. The hydrofluoric acid fog formed by air-jet atomization etches the glass surface to fabricate nanoporous structure (NPS) on glass surface. This NPS shows the enhanced average light transmittance of approximately 92.9% and the superhydrophilic property with a contact angle less than 1° which presents an excellent anti-fog property. Passivated by fluorosilane, the NPS shows nearly the superhydrophobic property with a contact angle of 141.2°. This fabrication method has shown promising application prospects due to its simplicity, low cost and efficiency, which can be easily applied to large-scale industrial production.

Poly(pyrene-co-3-methylthiophene), a new copolymer, was successfully synthesized by the direct electrochemical oxidation of a monomer mixture of pyrene and 3-methylthiophene in boron trifluoride diethyl etherate. The electrochemical performance of the copolymers was characterized by cyclic voltammetry. Ultraviolet visible (UV-vis) and Flourier transform infrared (FI-TR) were used to characterize the structure of the copolymers. In addition, the resulting copolymers were found to partially dissolve in some organic solvents (e.g., dimethyl sulfoxide). Fluorescence spectroscopy revealed that not only can the copolymers emit different photoluminescence under 365 nm UV light in the dimethyl sulfoxide solution, but also their emitting properties can be controlled by changing the monomer feed ratios.
