Abstract
XPS analysis is used in studying surface chemical composition and structure of ultrafine raw Al powder and PVP/Al composite powder, respectively. It shows that: in PVP/Al composite powder’s surface, comparing with raw Al powder, relative content of Al decrease and relative contents of C and N increase. New chemical bonds are formed in PVP/Al composite powder’s surface, and it is certain that, these new chemical bonds derive from N atom and O atom of PVP’s pyrrole with Al atom in Al powder surface.
