A unique technology to transform inorganic nanorods into nano-networks

An inorganic nano-network of attapulgite is formed from rigid nanorods using ion beam bombardment. The structure of the nano-networks depends on the ion beam fluence for the same ion energy. Scanning electron microscopy reveals that ion beam bombardment improves the dispersion of the attapulgite particles and the change in the shape of the rod-shaped attapulgite particles stems from the thermal stress induced by ion beam bombardment. This phenomenon is more obvious for higher ion fluences. The bent or twisted rod-shaped attapulgite particles cross-link to form a network structure, which is stable in water, and when the ion fluence is increased further, the cross-linked points are permanently sealed. The improved materials are more useful than clava attapulgite particles.
