1. Mechanical stirring: Short cut carbon fibers are added to a solvent and then stirred using a mechanical stirrer to help disperse the carbon fibers in the solvent.
2. Ultrasonic dispersion: Using an ultrasonic generator to generate high-frequency sound waves, short carbon fibers are dispersed in a solvent through the vibration and cavitation of the sound waves.
3. Surfactant: Add an appropriate amount of surfactant to the solvent to form a protective film on the surface of carbon fibers, reducing the interaction between carbon fibers and promoting their dispersion.
4. Nanocellulose: Add nanocellulose to a solvent and stir it with short carbon fibers to utilize the viscosity and dispersibility of nanocellulose to help carbon fibers disperse better in the solvent.
