Keysight Technologies Vapor Annealing Effect on Copolymers Studied by 7500 Atomic Force Microscopy with Environmental Control Application Brief Topography Introduction 7500 AFM system is comprised of a sealed environmental chamber. The Microphase separation is a ubiquitous desired vapor can be realized readily phenomenon in copolymer thin ilms by putting a small vial of corresponding due to the immiscibility and dissimilar solution into the chamber. In this appli- nature of their block components. Such cation brief, results on an atomic force segregations could occur in directions microscopy (AFM)-based investigations both perpendicular and parallel to on the annealing effect on triblock the underlying support substrate.
