AI Technical Summary
Existing carbon aerogels suffer from problems such as poor compressibility, low porosity, and poor structural stability in supercapacitors and strain sensors, which limit their widespread application.
Cellulose was oxidized to prepare nanofiber colloids, which were then mixed with chitosan. The mixture was mechanically crushed and freeze-dried to form chitosan/nanofiber aerogels, which were then carbonized to form nanofiber-based carbon aerogels with a three-dimensional spider web structure.
This improves the porosity and compressibility of carbon aerogels, enhances structural stability, and improves the specific capacitance and cycling performance of supercapacitors and strain sensors, making them suitable for large-scale preparation and industrial applications.
