Abstract: The present invention generally relates to a device and a process for performing large-scale noncovalent functionalization of 2D materials, with chemical pattern elements as small as a few nanometers, using thermally controlled rotary Langmuir-Schaefer conversion. In particular, the present invention discloses a device comprising a thermally regulated disc driven by a rotor with fine speed control configured to be operable with a Langmuir trough for performing large-scale noncovalent functionalization of 2D materials, achieving ordered domain areas up to nearly 10,000 μm2, with chemical pattern elements as small as a few nanometers. A process using the device for performing large-scale noncovalent functionalization of 2D materials with chemical pattern elements as small as a few nanometers is within the scope of this disclosure. The process we demonstrate would be readily extensible to roll-to-roll processing, addressing a longstanding challenge in scaling Langmuir-Schaefer transfer for practical applications.
