![]() For example, a 93-nm-thick PDMS nanosheet showed high flexibility with elongation at break of 338% and Young's modulus of 0.46 MPa. The mechanical properties of the PDMS nanosheets depended on the amount of cross-linker added in preparation. PDMS nanosheets, about 90–2500 nm thick, were prepared using a microgravure coater. In this study, free-standing PDMS thin films (PDMS nanosheets) were fabricated and characterized. ![]() PDMS can be rapidly cross-linked at low temperatures by a platinum-catalyzed addition reaction and is used to create nanostructures owing to its high formability. Polydimethylsiloxane (PDMS) is a biocompatible polymer that exhibits high flexibility and heat resistance.
