研究目的
To explore a new promising precursor for laser-induced graphene (LIG) with excellent durability under harsh conditions by converting synthesized poly(Ph-ddm) into LIG using a straightforward CO2 laser.
研究成果
Poly(Ph-ddm) was successfully converted into high-quality LIG with excellent durability under harsh conditions. The LIG demonstrated low sheet resistance, high specific surface area, and good electrochemical performance, making it a promising material for supercapacitors and water splitting electrodes. The study suggests that polybenzoxazine could be a versatile precursor for stable and durable LIG preparation.
研究不足
The study focuses on laboratory-synthesized poly(Ph-ddm) rather than commercial polybenzoxazine, which may limit the immediate scalability of the findings. Additionally, the chemical stability of LIG in highly acidic conditions (2 M HCl) showed some limitations.
1:Experimental Design and Method Selection:
The study employed a CO2 laser scribing machine to convert poly(Ph-ddm) into LIG. The laser parameters were optimized for graphene formation.
2:Sample Selection and Data Sources:
Poly(Ph-ddm) sheets were prepared as the precursor for LIG. The properties of LIG were characterized using Raman spectra, SEM, TEM, and XPS.
3:List of Experimental Equipment and Materials:
CO2 laser scribing machine (DA-LMN100-171101, III Lasers Technology, China), poly(Ph-ddm) sheets, and various analytical instruments for characterization.
4:Experimental Procedures and Operational Workflow:
Poly(Ph-ddm) sheets were laser-scribed under ambient conditions with varying laser fluences to optimize LIG properties. The LIG was then characterized and tested for stability and application in supercapacitors and water splitting.
5:Data Analysis Methods:
The quality of LIG was evaluated using Raman spectra, sheet resistance measurements, and electrochemical performance tests.
