Characteristics of the Topography Image of Polyurethane Polymer LB Films

폴리우레탄 고분자 LB막의 표면형상 이미지 특성

The synthesis and characterization of polymers for organic Metal/Insulator/Metal(MIM) devices were investigated from LB films. The physicochemical properties of the LB films were examined by UV absorption spectrum and AFM. The AFM images showed for network structure of polyurethane monolayer that the film formed an unsymmetry mesh with intermolecular interaction within the large scale. The stable images are probably due to a strong interaction between the monolayer film and Si substrate. We are unable to obtain molecular resolution in images of the films but did see a marked contrast between images of the bare substrate and those with the network structure film deposited onto it.
