研究目的
Investigating the programmable patterning of RGO/GO Janus paper for multiresponsive actuators.
研究成果
The study successfully demonstrates the fabrication of multiresponsive graphene actuators using laser-induced RGO/GO Janus film. The actuators respond to humidity, light, and electricity, showing potential for applications in soft robotics.
研究不足
The study focuses on the fabrication and characterization of multiresponsive actuators but does not extensively explore the scalability or long-term durability of these actuators in real-world applications.
1：Experimental Design and Method Selection:
The study employs a threshold-controlled direct laser writing (DLW) technology to pattern RGO/GO Janus film.
2：Sample Selection and Data Sources:
Graphene oxide dispersion was prepared by the Hummers’ method using commercial graphite flake.
3：List of Experimental Equipment and Materials:
A CO2 laser (
4：64 μm wavelength), JEOL JSM-7500 field-emission scanning electron microscope (FE-SEM), Rigaku D/MAX 2550 diffractometer, ESCALAB 250 spectrometer, Jobin–Yvon T64000 Raman spectrometer. Experimental Procedures and Operational Workflow:
GO dispersion was drop-casted on clean glass and dried to form GO paper. Laser direct writing was used to partially reduce GO paper. A tape was adhered to the RGO side, and the multilayer film was peeled off from the glass substrate.
5：Data Analysis Methods:
XRD patterns, XPS data, Raman spectroscopy were used to characterize the materials.
