摘要：

Patterning in evaporated polymer solutions based on amorphous polymers and chlorinated solvents has been investigated. Bilayered films patterned on two scales, i.e., 50 and 5 mu m, are obtained. The addition of polyorganosilane/-siloxane to solutions destroys the large-scale pattern. Poly(ethylene glycol) promotes the formation of more dense close-packed structures on the mesoscopic scale (approximate to 5 mu m). Short-range and mesoscopic (liquid-like) ordering of the honey-comb structures on the characteristic scale of 5 mu m is revealed with the statistical analysis of SEM images. Physical mechanisms responsible for patterning are discussed.
