- Abstract
- We investigated the in situ phase transition of the nanoscopic patterns on block copolymer thin films during nanoindentation by using a transmission electron microscope (TEM) with a specially designed nanoindenter. For the first time, we observed directly an in situ phase transition from lamellar microdomains to disordered states during the nanoindentation on a baroplastic polystyrene-block-poly(n-pentyl methacrylate) copolymer (PS-b-PnPMA) film. Through the in situ TEM observation, the mechanism of the nanoscopic pattern formation on a block copolymer thin film by indentation is fully understood.
