Abstract
A novel self-assembly phenomenon of nano-sized arrays by casting a dilute solution of a guest material on the friction-transferred poly(tetrafluoroethylene) (FT-PTFE) substrate was discovered. The arrays are composed of rod-like structures whose long axis is aligned perpendicular to the chain direction of the FT-PTFE. As a result, the arrays are highly anisotropic. This phenomenon was first observed for dilute solutions of polymers and organic materials cast and dried on the FT-PTFE. The arrays in question are formed regardless to the crystallinity of the guest materials. The ordered arrays are formed also from latex or colloidal metal suspension. In the arrays formed from colloidal gold, the gold nano-particles were arranged linearly and presented optical anisotropy We guess that the arrays are formed as a result of microscopic flow pattern at the meniscus of the drying solution film. The arrays in question may be categorized as a dissipative structure.
