摘要: The liquid crystalline phase behavior and sol–gel transition in halloysite nanotubes (HNTs) aqueous dispersions have been investigated by applying polarized optical microscopy (POM), macroscopic observation, rheometer, small-angle X-ray scattering, scanning electron microscopy, transmission microscopy. starts to form at the HNT concentration of 1 wt %, a full forms 25 % as observed POM observation. Rheological measurements indicate typical shear flow for with concentrations above 20 further confirm that occurs 37 %. Furthermore, exhibit pH-induced gelation more intense birefringence when hydrochloric acid (HCl) is added. findings shed light on behaviors diversely topological HNTs lay foundation fabrication long-r...
