AI Technical Summary
Existing methods for preparing conductive foams using carbon black result in uneven distribution, leading to reduced mechanical and electrical performance due to agglomeration and poor dispersion of carbon black particles, causing stress concentration and high volume resistivity.
A water-based polyurethane conductive foam is developed using a combination of modified carbon black and mesoporous oxide titanium, which improves dispersion and mechanical properties through a specific synthesis method, forming a complex network structure that enhances both mechanical and electrical performance.
The solution achieves improved mechanical strength and electrical conductivity by ensuring uniform distribution of carbon black within the foam structure, optimizing pore distribution and forming a stable network for efficient electron transport.
