Temperature induced healing of scratches in PS-PMMA

A before and after picture showing the same region of a PS-PMMA block copolymer. The “Before” image shows
a series of concentric scratches made with nanolithography. The “After” image shows the polymer fully healed
after elevating the sample temperature to 125°C. 2µm scan. Imaged with the MFP-3D AFM.
