Preparation of Highly Crystalline Magnesium Oxide and Polystyrene/Magnesium Hydroxide Composite Particles by Sol–Gel Processes in an Ionic Liquid
Abstract:
Highly crystalline magnesium hydroxide (Mg(OH)2) was obtained by sol–gel process using magnesium nitrate (Mg(NO3)2) with ammonium hydroxide (NH4OH) in a hydrophilic ionic liquid, 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) as a medium. Crystallite size of Mg(OH)2 obtained in [Bmim]Cl was larger than that obtained in 2-propanol (used as a medium for comparison), which indicates that [Bmim]Cl worked as a template. The obtained Mg(OH)2 was transformed to magnesium oxide (MgO) by heat treatment under atmospheric pressure. After heat treatment, crystallite size of the MgO obtained in [Bmim]Cl was also larger than that obtained in 2-propanol, reflecting the crystallinity of Mg(OH)2 before heat treatment. Polystyrene (PS)/Mg(OH)2 composite particles were successfully prepared by seeded dispersion sol–gel process in [Bmim]Cl in the presence of PS seed particles. The composite particles had smooth surfaces and core–shell morphology consisting of PS core and Mg(OH)2 shell having high crystallinity. The Mg(OH)2 ...read more
