DESCRIPTION:Polymers are ductile materials that are easy to process. Tradi
 tionally they are used as packaging and construction materials. The contro
 l over the molecular structure and the way they pack in three dimensional 
 arrangements made them also suited as functional elements in (opto)electro
 nics products. In order to maintain the ease of processing while controlli
 ng the morphology down to the level of tens of nanometers\, we developed s
 pecial processes based on self-organization and well-controlled diffusion 
 during their formation.  This has led to unique properties\, such as selec
 tive reflection of circularly polarized light\, or unique products\, such 
 as paintable displays. In addition to the diffusion processes on microscop
 ic scale\, the control over the adjusted morphology also enables us to cre
 ate motion in the polymers over macroscopic dimensions. A property that le
 ads to new applications such as thin-film actuators or artificial muscles.
