Abstract
The molecular configuration of isotactic PMMA Langmuir-Blodgett (LB) f ilms was investigated with atomic force microscopy (AFM). AFM images o f the isotactic PMMA LB films, transferred at the surface pressure of 15 mN/m, show a closely packed well ordered arrangement with helical c onfigurations. The appearance of the AFM images and the width indicate that the transformation at the surface pressure of 8 mN/m corresponds to the formation of single strand helix.
