Preparation of Mg(OH)2 hybrid pigment by direct precipitation and graft onto cellulose fiber via surface-initiated atom transfer radical polymerization

- Adsorbed anionic dye molecules are conducive to preferential growth of (0 0 1) plane of Mg(OH)2 crystal for Mg(OH)2 pigments.
- Uniform coverage of nanosized Mg(OH)2 pigments on fiber surface is achieved via surface-initiated ATRP.
- About 4 wt% of Mg(OH)2 pigment on fiber surface shortens nearly half of burning time of cellulose.
