摘要
In this paper, non-aqueous Fe(OH) 3 /palygorskite dispersion was prepared and its liquid crystal phase behavior was investigated. Positively charged Fe(OH) 3 colloidal particles were put in to non-aqueous and organically modified palygorskite dispersion. The effects of organically treated palygorskite and Fe(OH) 3 on the preparation of stable palygorskite dispersion were characterized with FT-IR, XRD , Contact Angle measurement , Zeta potential detection, Settlement measurement and SEM , respectively. The addition of Fe(OH) 3 particles shifted the concentrations of the coexisting isotropic and nematic phases to higher values while at the same time markedly accelerated the phase separation. The influence of Fe(OH) 3 particles on the dispersion in magnetic field was also discussed.
