Experimental exploration of SMART photochemical approach for surface modification of carbon black

Photochemical reactions have defeated thermal ones on eco-friendly grounds, yet are not exact replacement in certain situations, particularly for photochemical reactions in the presence of colored particles. Irradiating photoinitiator (PI) in the presence of colored filler comes up with the limitation of radiation absorption by filler and not PI. Current research work is based on SMART photochemical approach for surface modification of Carbon Black (CB), where competition has been eliminated by parting components during initiation step. Reported photochemical approach is simple, effective and reproducible, with 5-10 wt% of modifier incorporation on CB surface. Other than being eco-friendly, this photochemical approach proves to be effective for thermally unstable materials. Efficiency of SMART approach has been verified by applying it on different types of CBs, in the absence and presence of solvents. Results of CB photochemical modification have been verified by different instrumental techniques including XPS, SEM, TGA, Raman, FTIR, DLS.
