主　　题：antireflection self-cleaning multifunctional surface flexible film biomimetic fabrication 

摘      要：Inspired by cicada wings,a flexible film with self-cleaning and broadband antireflection properties was fabricated with a rapid,straightforward and cost-effective *** cicada wing was selected as the original template,and a polymethyl methacrylate (PMMA) negative replica was obtained by evaporation solvent *** original template was directly peeled ***,the polydimethylsiloxane (PDMS) was spread in the as-prepared PMMA negative *** curing and peeling processes,the PDMS positive replica was manufactured *** morphologies and performances of cicada wings were perfectly inherited by the PDMS positive *** is more,the excellent optical property of cicada wing was investigated experimentally and *** with fiat PDMS film,the average reflectivity of structural PDMS film was reduced from 9% to 3.5% in the wavelength range of 500 nm-900 *** excellent antireflection properties of bio-inspired antireflection film can be attributed to the nanostructures which achieve a gradient refractive index between air and the materials,and the mechanism of the antireflection properties was revealed via effective medium ***,the bio-inspired broadband antireflective film exhibited superhydrophobic property after the surface treatment (a 152.1° water contact angle),and it also displayed satisfactory *** work provided a universal method to fabricate the exquisite biological structures,realizing the transfer of structure and ***,the multifunctional antireflection film exhibited the potential value for applications in optical communications,flexible display screens,and anti-dazzle glasses.
