摘要

A microwrinkle surface made of UV-curable resin is known to reduce the regular reflection or glare of light because the wrinkle structure diffuses the incident light. However, the regular reflection cannot be reduced completely because the back side of the film or substrate reflects light as well. To achieve greater reduction in regular reflection, we developed a double-sided nanowrinkle film prepared on a water surface. A mixture of dipentaerythritol penta-/hexa-acrylate (DPHA), 1,6-bis(acryloyloxy)hexane, and 1-hydroxycyclohexyl phenyl ketone (HCK, photoinitiator) was spread on a water surface containing an inhibitor (Cupferron), and exposed to UV light. The photopolymerization reaction shrank the liquid film, and solidification occurred simultaneously in the core of the liquid film. However, the top and bottom interfaces contacted air and water, respectively, and the oxygen in air and the inhibitor in water retarded photopolymerization. The difference in photopolymerization rates results in a mismatch of shrinking speed between the core and each interface, and forms a double-sided wrinkle film. The size of the wrinkles within 0.7 μm of air interface was obtained by changing the concentration of DPHA. The double-sided wrinkle film reduced the regular reflection of laser light (λ = 520 nm) more than the single-sided nanowrinkle film.
