Strategy to Prepare Core–Shell Microspheres for Laser Direct Writing on Polymers: Microemulsion Method
In this study, new core–shell microspheres for
polymer laser
direct writing (LDW) were successfully designed and prepared by a
facile one-step microemulsion method. The color-changing core–shell
microsphere consists of a SnO2 “core” which
can absorb near-infrared (NIR) laser energy and a polyphenylene oxide
(PPO) “shell” which can be easily carbonized at high
temperatures. Owing to the unique core–shell structure, the
SnO2@PPO microsphere remarkably enhanced the polymer LDW
performance. SEM, TEM, and EDS indicated microspheres were regular
spheres with an average size of 15.1 ÎĽm. Raman spectroscopy
and XPS revealed that the SnO2 absorbed NIR laser energy
to cause instantaneous high temperatures, leading to the carbonizing
of the PPO shell. Thus, the color-change mechanism of the polymer
during NIR LDW was confirmed as the formation of amorphous carbon
by high-temperature carbonization. We believe these novel microspheres
will have wide applications in the field of polymer LDW. Besides,
the concept of preparing core–shell microspheres by the one-step
microemulsion method provides a new idea for designing color-changing
microspheres
