Mechanism of high temperature induced destabilization of nonpolar organoclay suspension.
Journal of Colloid and Interface Science(2019)
摘要
High temperatures induced the complete desorption of physically adsorbed DODMAC molecules from particle surfaces, the partial desorption of ion-exchanged dimethyldioctadecylammonium ions (DODMA ions) from particle surfaces, and the partial transfer of ion-exchanged DODMA ions from the surfaces to the interlayers. Importantly, desorption of ion-exchanged DODMA ions resulted in destabilization of the organoclay suspensions at high temperatures.
