文摘

The preparation of periodical structures on the polymer surface using photo-directing of Marangoni flow is described. The surface tension gradient appears due to the spatial distribution of energy in the laser beam and leads to the creation of periodical structures. The method allows the creation of surface structures with different symmetry, from simple line array to more complex geometries.
