White carbon black: a "cross-border pioneer" from traditional industry to future manufacturing

The application boundaries of white carbon black are continuously expanding. In the field of coatings, by adding gas-phase white carbon black, the scrub resistance of exterior wall coatings has been improved from over a thousand to over ten thousand, and the artificial accelerated climate aging time has been increased from 250 hours to 600 hours. In the field of plastics, fumed silica can improve the transparency of polystyrene film by 20%, the strength by 30%, and the waterproof performance and anti-aging performance are significantly improved.


More cutting-edge research applies white carbon black to the field of 4D printing. By combining shape memory polymers with white carbon black nanofibers, smart materials that can respond to temperature, light, or magnetic fields can be prepared. For example, the white carbon black/polycaprolactone composite material developed by a certain research team can automatically curl into a predetermined shape in 40 ℃ hot water, and is used to prepare degradable vascular stents and flexible electronic sensors.
