Traditional materials often remain unchanged, while white carbon black is achieving dynamic response through intelligent design. Researchers grafted thermosensitive polymers onto the surface of white carbon black to prepare an intelligent glass coating with reversible light transmittance regulation. When the temperature increases, the polymer shrinks and exposes the white carbon black nanopores, causing the glass to become foggy; Restore transparency after cooling. In the aerospace field, shape memory white carbon black composite materials can automatically repair microcracks after heating, integrating structural damage detection and repair. More cutting-edge is that photoluminescent white carbon black nanoparticles can achieve dynamic encoding of anti-counterfeiting labels, displaying different patterns with each scan, providing ultimate protection for high-end products. These 'thinking' white carbon black materials are redefining the material foundation of the intelligent era.
