TECHNOLOGY FOCUS - POLYMERS - Preferred Method: An electrical field treatment is performed at 200-10000 V/cm for 1-90 hours for the film at higher than the transition glass temperature of the polymer and cooling down to room temperature. The step of coating the uniform solution on the plate electrode, the container of the surface of an object comprises immersion, spin-coating, spreading or mechanical printing. Preferred Condition: The heating step is carried out at 100-300degreesC for 1-50 hours. The cooling down step is at 30-50degreesC/hour. Preferred Composition: The polymer substrate is 30-90, preferably 60-90 wt.%. Preferred Component: The polymer substrate is polyalkylene oxide, polyvinyl fluoride, polyacrylonitrile, polyester, polyether, polysulfone, polyethylene oxide (PEO), polyvinylidene fluoride, poly(methyl methacrylate), polysiloxane, polyphosphazene or their derivates.
