摘要: Nanopillar arrays have attracted considerable attention lately based on confinement effects and large surface to volume ratios. In this study, we demonstrated an efficient low-cost method for fabrication of large-area high aspect ratio nanopillars based on thiol-ene. Anodic aluminum oxide (AAO) template with ordered deep hole array was employed as the master mold. The low-viscosity and highly rigid UV-curable thiol-ene polymer was used as the structure material. The deep holes were filled with the liquid thiol-ene by overcoming the …
