Dual Emulsion Fabrication Approach to Core–Shell Microspheres for Polymer Laser Direct Writing

A unique BaTiO3@PS core–shell microsphere responsive to a near-infrared (NIR) laser is designed and successfully prepared using a dual water-in-oil-in-water emulsion method. The BaTiO3 powder was precisely encapsulated in the PS resin in a uniformly dispersed state, with an average particle size of 10.8 μm. The core material, BaTiO3 powder, has a high photothermal conversion efficiency. It cooperates with the external easily carbonized PS to effectively improve the performance of the polymer NIR laser direct writing (LDW). SEM and EDS results confirm the successful preparation of regular microspheres. Raman tests and XPS analysis indicate that the mechanism of black pattern formation of the polymer under the NIR laser is attributed to the generation of amorphous carbon during the LDW process. These core–shell structured microspheres have expanded the application scope of polymer LDW, rendering it more practically valuable. Additionally, this dual emulsion approach has introduced new concepts for designing and fabricating color-changing microspheres

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 μm. 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
