Multiple Artistic Images Design of Polymers Realized by Microlens Array Structure

Multiple artistic images of polymers can be obtained through microlens array structure. Water droplets are used as templates to prepare ordered array of polymer. To prepare the ordered arrays, the water droplets firstly condense on the surface of cold polymer solution and arrange ordered array during the preparation procedure. The polymer material form regular porous membrane after solvent evaporation. Ordered porous polystyrene array membrane was prepared employing this method and acicular polystyrene array membrane was further obtained by removing the upper layer of ordered porous array structure. Ordered porous polystyrene array membrane can also be used as template for spherical microlens array of polyvinyl alcohol. The obtained microlens array exhibited microscopic imaging performance.
