Novel nano- And micro- fabrication technique of polymer materials based on self-organization

We have utilized dynamic processes and dissipative structures emerged in the casting polymer solution for micro- and nano-patterning of polymer materials. We have found that the typical dissipative structures were formed in the casting process of polymer solutions on solid surfaces. Dynamic regular structures formed in casting polymer solutions are fixed as regular patterns, stripes, and lattices, etc., of polymer materials including nano-particles. We have also found that micro porous polymer films were prepared from water-immiscible solvent under humid casting condition. The patterned films can be applicable to optical and photonic devices as well as biomedical devices.
