Abstract
This work reports on hydrogen bond energy of sulphated cellulose nanocrystals (CNC) obtained from rubber wood (RW) cellulose for effective steric stabilization of magnetite nanoparticles obtained via the modified Massart's method. The particles morphology, structure and crystallite properties were investigated by using microscopic techniques. The magnetic properties of Fe O nanoparticles were investigated by using physical 3 4 property measurement system. The average width of CNC was ≈20 nm with length of between 190 nm-300 nm. Changes in the hydrogen bond energy of the RW cellulose, during acid hydrolysis, were investigated by using the FT-IR hydrogen bonding energy calculation. The CNCs capped Fe O particles synthesized, were 3 4 monodispersed and oval in shape (with average particle diameter of ≈4 nm). The Fe O nanoparticles obtained, 3 4 exhibited superparamagnetic behaviour and saturation magnetization (Ms) of ≈67.5 amu/g
