Herein, we demonstrate that a variety of nanotextures with unprecedented control of sizes, shapes, and orientations (e.g., nanowires, plasmonic nanofunnel, nanoellipsoids, complex nanogratings) can actually be fabricated by directional photofluidization lithography. The term “photofluidization” describes the photosoftening of the azopolymer by the repeated photoisomerization of azobenzene molecules. More significantly, different from the thermal-induced isotropic fluidization of thermoplastic polymers, the direction of the photofluidization of azopolymers proved to be strongly dependent on the polarization of incident light. This ability allows us to generate a variety of nanostructural motifs with unprecedented control of and flexibility in the structural features (e.g., shapes, sizes, and orientation). |
