OTF-1200X-II-PE-RR Roll to Roll PE-CVD System with 1200°C Tube Furnace and 300W RF Plasma for Continuous 2D Film Growth on Foil or Wire
The OTF-1200X-II-PE-RR is a laboratory-scale roll to roll plasma-enhanced chemical vapor deposition (PE-CVD) system engineered for continuous synthesis of graphene and other two-dimensional films on flexible substrates such as thin foil or wire. This system addresses the need for scalable film growth by integrating a controlled substrate feeding mechanism within a high-temperature tube furnace environment.
The core of the system is an 80 mm outer diameter quartz tube furnace featuring two heating zones: a 440 mm programmable heating zone capable of reaching 1200°C for short durations and a 250 mm constant temperature zone for stable processing. The furnace is paired with a 300W radio frequency plasma source operating at 13.56 MHz to enhance chemical vapor deposition reactions. Substrate handling is facilitated by two vacuum chambers equipped with reeling rollers that allow substrate speeds from 1 to 400 mm/min and include a precision tension control mechanism to maintain substrate integrity during processing.
Key Features
- Dual-zone tube furnace with max 1200°C temperature for up to 60 minutes and continuous operation at 1100°C
