Freeze Granulation for distribution of carbon nanotubes in alumina matrix

New approach for distribution of carbon nanotubes in alumina matrix Ondrej Hanzel, , Jaroslav Sedláček , Pavol Šajgalík Alumina–carbon nanotubes composites were studied with respect to obtain the homogeneous distribution of nanotubes within the alumina matrix. Disaggregation and uniform dispersion of carbon nanotubes in alumina matrix are crucial requirements for improvement fracture toughness and also… Continue reading Freeze Granulation for distribution of carbon nanotubes in alumina matrix
