Efficient Synthesis of High-Quality Carbon Nanotubes Using Induction Heating Technology

This study reports the synthesis of carbon nanotubes (CNTs) using induction heating technology as a rapid, clean, and inexpensive method. CNTs were synthesized on a metal alloy substrate. The CNTs growth were purposed to optimize by controlling work pressure, growth temperature, and growth time in the high vacuum chamber with induction heater. The CNTs were characterized by scanning electron microscope (SEM) for surface analysis and field emission properties were measured. Compared to traditional thermal chemical vapor deposition (CVD) synthesis methods with graphite heater, induction heating technology offers a more efficient and practical alternative for producing CNTs with potential applications in various fields.
