used in materials synthesis
and device processing. In this work, we developed three-dimensional
(3D) printed reduced graphene oxide (RGO)-based heaters to function
as high-performance thermal supply with high temperature and ultrafast
heating rate. Compared with other heating sources, such as furnace,
laser, and infrared radiation, the 3D printed heaters demonstrated
in this work have the following distinct advantages: (1) the RGO based
heater can operate at high temperature up to 3000 K because of using
the high temperature-sustainable carbon material; (2) the heater temperature
can be ramped up and down with extremely fast rates, up to ∼20 000
K/second; (3) heaters with different shapes can be directly printed
with small sizes and onto different substrates to enable heating anywhere.
The 3D printable RGO heaters can be applied to a wide range of nanomanufacturing
when precise temperature control in time, placement, and the ramping
rate are important.
