Formation of Langmuir-Blodgett (LB) films of novolak resins has been s
tudied and the films have been microscopically characterized by an ato
mic force microscope (AFM). It is found that uniform LB films are form
ed by using fractionated novolak resins. AFM measurements indicate tha
t the LB films formed from the novolak resins of low molecular weight
have ordered structures.
