Abstract: The present disclosure provides a solid carbon black material including an oxidized carbon black having a pH of greater than 7, compositions including such solid carbon black material and a polymer component as well as articles made therefrom. The disclosure also concerns a method for manufacturing said solid carbon black material. The solid carbon black material is particularly useful for obtaining rubber compounds with low hysteresis, e.g. for the production of energy-saving tires, with enhanced curing rates compared to the use of conventional oxidized carbon blacks.

Abstract: An environmentally-friendly flexible conductive polyurethane (PU) and a preparation method thereof are disclosed. The environmentally-friendly flexible conductive PU is prepared by subjecting a mixture of a component A and a component B in a specified mass ratio to in-situ solvent-free polymerization, where the component A is prepared from a polyol, a T-type chain extender, a diselenide diol, high-conductivity carbon black, a dispersing agent, a catalyst, and a leveling agent, and the component B is prepared from a polyisocyanate, a polyol, a multi-walled carbon nanotube (MWCNT), and a dispersing agent. The PU has a reliable electrically-conductive function, and shows a self-healing function under room temperature or light conditions when damaged, wherein a microphase separation value HBI (0.5 to 3.0) of soft and hard segment molecules can be adjusted to achieve different hand touches and different mechanical properties, and an organic pollutant emission (volatile organic compound (VOC)) is less than 50 mg/kg.
