A Comparison Study of Magnetic Stirrer and Sonicator Technique to Disperse 1% Span20 Treated Layered Double Hydroxides (LDHs)

Abstract

Effect of particle size reduction and dispersion of 2-dimensional material, layered double hydroxide (LDHs), prepared by co-precipitation method with the primary particle size of around 100 nm, was investigated. Two simple laboratory dispersing techniques including magnetic stirrer, and sonicator were applied to disperse agglomerated LDHs in 1 wt.% Span20 solution, act as a stabilizer. Magnetic stirrer showed a cluster of agglomerate particles with improved dispersion while, agglomerates with single stack LDHs were presence in case of sonicator product.
