Atomic force microscopy (AFM) is a powerful tool to study materials at a molecular (or atomic) level, however, it is still challenging to observe soft materials, such as polymers, in the high resolution. We demonstrated that AFM observations of polymers in a resolution close to or better than 1 nm were possible by using monolayers prepared by Langmuir-Blodgett (LB) technique or spin casting followed by annealing under solvent vapors. We believe that the molecular level information is essential to improve our understanding of polymers and to build up nano-materials based on polymers.Appealingpoint:AFM is a popular instrument, however, even now, the observation of Special objectivespolymers at the molecular level is only possible in a limited number of laboratories.
