摘要
Morphology of synthetic imogolite nanotubes formed in droplet evaporation was investigated by transmission electron microscopy and electron diffraction. The nanotubes form a dense entangled network at higher concentrations,while at lower concentrations the nanotubes are liable to form ori-ented bundles. Under enthanol atmosphere,individual dispersion of nanotubes was observed for the first time,which reveals the length polydispersity of synthetic imogolite nanotubes.
