With industrial grade Al(OH)3 as raw materials, the self dispersion nanosized AlOOH crystal powder were prepared by the sol-hydrothermal method. The results of XRD and TEM show that the nanosized AlOOH could automatically disperse to a single-dispersing state in water without surface modification, dispersant, additive and accessional conditions (ultrasonic wave dis-persing, ball-mill dispersing). The application results of the product indicate that the nanosized AlOOH can be composed into a toughened nanocomposites without surface modification. Accordingly, the self dispersion characteristic and mechanism of hydrothermal crystallization and charging composite dis-persion of nanosized AlOOH are found, and a new technique of preparing polymer/inorganic nano-composites is proposed, which is called blending compositing new techniques of sol even dispersing at quasi-homogeneous phase.
