Cellulose nanocrystals (CNC) quickly ignite in the vicinity of flame and heat, owing to their structural resemblance to cellulose, mainly the crystalline part of cellulose. Therefore, it is essential to modify its structure using fire inhibitors for expanding its utilization domain for cellulose-based high-quality materials. Hence, in this study, we have modified the configuration of TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) oxidized CNC by various types of flame retardants, containing the following three combinations to evaluate its fire behaviour: ammonium dihydrogen phosphate and albumin, silicon dioxide and methyltrimethoxysilane, and the mixture of the ammonium dihydrogen phosphate, albumin, silicon dioxide, and methyltrimethoxysilane, respectively; assuming that ammonium dihydrogen phosphate salt and silicon dioxide act as a
fire retardant in each run.
Keywords: Cellulose nanocrystal, Flame retardancy, Cellulose-based high-quality materials
